DEET deters mosquitoes in three ways

It is a known fact that the smell and taste of DEET deter mosquitoes. DEET has been the most effective insect repellent for decades. But there is a third way that contributes to the protection against mosquitoes. Recent research by a team of American researchers shows that contact with DEET is also experienced as unpleasant by mosquitoes.

Yellow fever mosquitoes (Aedes aegypti) prefer not to land on skin rubbed with DEET. This is written by researchers led by Leslie Vosshall of The Rockefeller University in New York in Current Biology magazine this week.

DEET is a yellowish oily substance that does not evaporate very quickly. This ensures that the layer applied remains effective longer, but the mosquito-repelling effect of the odour is limited. DEET only repels insects when they are close. This is further proof that products such as DEET-impregnated bracelets do not work, other than that the mosquito will not land on the bracelet itself, but rather on the skin next to it. However, anyone who rubs DEET on exposed skin is protected against mosquito bites for hours.

“DEET may be the most researched remedy with by far the most evidence of its safety and excellent protection against mosquitos and ticks!”

The bitter taste of DEET

Possibly mosquitoes taste the substance, which is described by humans as bitter. But it is not clear whether this bitter taste contributes to deterring biting mosquitoes.

In the new study, Vosshall and her colleagues demonstrate with a series of tests that the mosquito’s legs are sensitive to DEET. A volunteer applied DEET and put on a long glove with an opening of one and a half millimetres in which the mosquito could stick its snout. In this way, only the mouthparts of the mosquito came into contact with the DEET, but its legs remained on the latex of the glove. In this way, mosquitoes were not deterred by the DEET and stung as often as test mosquitoes on untreated skin.

That is why the researchers decided to apply a layer of quick-drying glue to the legs in a subsequent trial. In earlier research on fruit flies, this was also done to investigate whether these flies can detect with their legs whether they are walking on food. In the case of mosquitoes, all six legs were covered with quick-drying glue. It turned out that they were no longer sensitive to DEET on the skin.
DEET effectively repels mosquitoes in any way. But Vosshall hopes that this insight can lead to the development of new insect repellents, which use the sensitive mosquito legs.

“It’s especially interesting because we’ve known this remedy for a long time, about seventy years”, says Bart Knols. He did not participate in the research, but is an entomologist at Radboud University and wrote the book ‘Mug’ (Mosquito). Every year, some 200 million people use DEET as protection against mosquitoes.

“We just knew all along that it worked, but we didn’t know how.” Knols calls the research ‘a first step in the unravelling of the functioning of DEET’. “And if we continue in a positive way, this research might help us to find new drugs that also work well against mosquitoes.

Awareness for World Malaria Day 25 April

Awareness for World Malaria Day 25 April

News

World Malaria Day

Thursday 25 April is World Malaria Day. On this day we want to raise awareness of this deadly disease that affects more than 214 million people annually. Still, more than 430,000 die of malaria, and most of the victims are children. The disease claims around 288,660 children’s lives under 5. This has to stop! Care Plus®  is committed to a malaria-free world by 2030. Will you help?

What is malaria?

Malaria is a severe infectious disease, caused by the sting of an infected mosquito. There are four forms of malaria. The most dangerous form is malaria tropica and without treatment, it can be fatal within a few weeks. Here are a few malaria facts:

• Every 60 seconds a child dies of malaria.
• 430.000 malaria deaths every year.
• Occurs in (sub) tropical regions, mainly in African countries.
• In a few regions, the malaria mosquito has become resistant to malaria remedies/medication.
• Occurs in 109 countries.
• No vaccine available, preventative medication is available.

Up to now, we have known malaria as the ‘imported’ disease in the Netherlands, due to travel between the Netherlands and (sub) tropical regions. The native mosquito would not survive in our weather conditions. However, due to climate changes in Europe, it’s becoming easier for the mosquito to survive and transmit diseases. The mosquito has a good chance of survival in areas around the Mediterranean Sea. Read here for more information on infectious diseases by mosquitoes in Europe.

Well-protected when travelling

Are you travelling to a country where malaria occurs? Make sure you are protected! The risk of contracting malaria can be reduced by taking malaria pills. Also, wearing clothes that cover the skin and using mosquito nets and Anti-Insect are good ways to reduce the risk of infection.

There is currently no effective vaccine available for malaria. You can get preventive pills on prescription from your doctor when you are travelling to a malaria region. There are currently three different types of pills available, each with their own active ingredient. However, the pills are a mere preventive measure and there is still a chance you may contract malaria. Thanks to the medication, it will take longer before harmful complications occur, giving you more time to start treatment.

The type of pills your GP will prescribe depends on:

  • What malaria region you are travelling to.
  • The duration of your stay.
  • Your health condition.
  • Any other medication you are using.

Do you want more information or make an appointment? We refer you to the NPHI.

Extensive study with first vaccine

Research and developments in a malaria vaccine are ongoing. Last Tuesday, some doctors started an extensive study in Malawi in which children must be protected from the deadly mosquito. 120,000 children aged 2 and below were vaccinated with this new vaccine. The study will continue until 2023 and comparable campaigns will be launched in the coming weeks in Ghana and Kenia.

News

Mosquito plague is imminent

Although most of us look forward to the predicted summer temperatures, the rising temperatures of the last few days are already causing increased growth of the mosquito population. According to Mosquito Radar, the mosquito nuisance will further increase in the coming days. Time to take the necessary precautions! Look below for all tips and tricks for a good night’s sleep without buzzing and itchy mosquito bites!

Prevention

Prevention is better than cure. This also applies to mosquitoes. Fortunately, you can take the necessary measures to reduce the risk of mosquito bites. It is always a good idea to check the room for mosquitoes before you go to sleep and to place insect screens on window and door frames. Another 5 preventative tips below:

  • Wear light coloured, finely woven clothing.
  • Wear covering-clothing with long legs and sleeves.
  • Remove/avoid places with stagnant water.
  • Sleep under a good quality mosquito net.
  • Apply Anti-Insect DEET or Anti-Insect Natural to exposed skin.

 

Treatment

Have you been bitten by a mosquito after all? Fortunately, there are several things you can do to reduce the itching. You can easily extract the venom with the Venimex venom extractor, which will significantly reduce swelling and itching. Click-Away Bite Relief reduces the itching and swelling within several minutes. A calming gel can reduce pain and itching and cool and soothe the skin.

 

Climate change causes infectious diseases by mosquitoes in Europe

Tropical infectious diseases transmitted by mosquitoes occur more frequently in Europe due to climate change. Scientists have warned against this at a European congress about infectious diseases (ECCMID) in Amsterdam. It concerns diseases such as dengue, chikungunya and leishmaniasis.

Until recently, these diseases only occurred as imported diseases that travellers brought with them from (sub)tropical regions. Because of longer periods of warm weather, mild winters and a significant amount of rain, these mosquitoes can be found increasingly closer to home.

The tiger mosquito, the mosquito in question, thrives especially well around the Mediterranean. The tiger mosquito can be found in Italy and Spain, but also in parts of southern Germany and Switzerland. The tiger mosquito is occasionally found in the Netherlands, usually in imported second-hand car tyres or ‘lucky bamboo’. So, be warned when making a trip within Europe and always ensure necessary prevention.

Tick season started early this year

The extremely mild winter days in our country have caused nature to be in a bit of a muddle. Hedgehogs are coming out of hibernation much too early, and ticks have free rein in forests and heathlands. 

This could be yet another year where a record number of tick bites are reported. Ticks thrive in the mild conditions of previous months – they become active as soon as the temperature rises above 5 to 10 degrees – and that is the reason why they have come out early this year and in greater numbers. A good reason to take the right preventative measures before going outdoors.

Care Plus® is committed to stop ticks every year at the start of each tick season: with information about ticks, how to prevent a tick bite and how to remove a tick. Ticks occur in the Netherlands more frequently nowadays and a bite can have unpleasant consequences. It is important to know what to look out for.

Ticks do not fall from trees, as many people think, but live predominantly in shrubs, grass and heathland, including gardens, golf courses and footpaths where you walk your dog.

A tick bite can be prevented by:

It is a good idea to check yourself and each other after having been outdoors. Ticks are small and easy to miss. Have you been bitten? Remove the tick as quickly as possible with tick pincers. Disinfect the area of the bite with some alcohol, and keep an eye on the affected area.

Malaria facts

  • Severe infectious disease, caused by the stink of an infected mosquito.
  • The most dangerous form of Malaria Tropica can result in death within several weeks without treatment.
  • Every 60 seconds a child dies of malaria.
  • 1,000,000 malaria deaths annually.
  • Found in (sub) tropical locations. Native mosquitoes are now also found in Europe due to tourism, transport and world trade.
  • In a few areas, the parasite has become immune to malaria remedies/medicines.
  • Found in 109 countries.
  • No vaccin is available.

Repelling mosquitoes

Repelling mosquitoes is usually a matter of common sense. A few simple tips will help you on your way. Do not use insect repellent as a first resort, instead, critically look at your environment. Flowerpots filled with water and blocked drains are the ideal habitat for mosquitoes. We recommend turning the pots upside down and unblocking the drains: free, simple and very effective. The malaria mosquito tends to bite after sundown. By installing insect screens in window and door frames and closing these after sundown, you will guarantee a mosquito-free (bed)room. While travelling, you can create an insect screen with our Bug Sheet. A well-functioning air conditioning system also helps to deter mosquitoes. We also advise covering your body with clothing as much as possible: long trousers, long sleeves, socks and closed shoes. Our clothing line is naturally insect repellent and sun resistant, so without impregnated textile. Better for the user, whose skin is in direct contact with the fabric, and better for the environment. We were the first ones on the market in 1997 with this innovative product.

 

Fighting mosquitoes

Sleeping under an impregnated mosquito net guarantees a safe and good night’s sleep. Our first mosquito nets were launched in 1997. Despite the minimal amount of impregnation, the nets are very effective for the protection against (malaria) mosquitoes, lice, bed mites and fleas. The requirements of travellers change all the time and technology is keeping up. We will launch a range of lightweight mosquito nets with durable impregnation this year, in accordance with applicable regulations concerning biocides within the European Union and beyond, and in accordance with WHO guidelines. The nets have been awarded by the ANWB professional jury. Due to the material-saving square mesh, our lightweight range is up to 50% lighter than regular nets.

Only after all this, we recommend using an insect repellent with DEET on exposed skin. Our Care Plus Anti-Insect DEET 50%, part of our range since 1994, provides up to 10 hours of protection against (malaria) mosquitoes. As an alternative, we offer Anti-Insect Natural without DEET made with natural lemon eucalyptus extracts. Natural, with 30% Citriodiol®, provides up to 6 hours of protection.

 

Luring mosquitoes

Tropicare supports pioneering scientific research of the Wageningen University Laboratory, in search of a solution to keep the (malaria) mosquito away from people. A study group led by Professor Takken has developed substances that attract mosquitoes. These attractants are used to lure mosquito populations away from African villages and catch them, so that the risk of a malaria mosquito’s bite is reduced to such an extent that malaria disappears.

We donated 28 mosquito traps, the MMX Counterflow Mosquito traps, in 2012. The traps are important to gain information on malaria mosquitoes in and around the house. Based on this information, new control techniques can be used. A field study is being carried out on the Kenyan Rusinga Island. Last year, Arnoud Aalbersgerg, founder and CEO of Tropicare, visited the project. The results of the field study are promising. The mosquito traps bring down the mosquito populations in the huts, and the traps’ battery and solar panel provide an additional advantage. They provide electricity for lighting and charging facilities for mobile phones (because everyone has one!).

In order to be able to offer travellers a solution, we are interested in gaining experience with a portable mosquito trap. Another wonderful innovative effort for Care Plus and a step closer to a malaria-free world by 2030!

Clean drinking water when travelling

In many countries, drinking water is often less reliable than you are used to at home. Contaminated water can contain protozoa (single-celled organisms), bacteria and viruses. For drinking water contaminated with microorganisms, one harmful organism can already pose a health risk. For example, infectious diseases of particularly the gastrointestinal tract, such as diarrhoea, typhoid, cholera and hepatitis A.

When purifying water, it is important to deactivate protozoa, bacteria and viruses. Boiling water is an easy and effective method. However, this is time-consuming and not always possible. Deactivating protozoa and bacteria can be done with membrane 0.1-0.5 micron (pore diameter) filter. Deactivating bacteria and viruses can be done with the chemical treatment of sodium hypochlorite, such as drinking water disinfectant Hadex®. The Hadex® chlorine solution does not affect protozoa.

Tips against mosquitoes

You know the story: You’re having a nice evening outdoors and you’re under attack by mosquitoes. Or children can’t get to sleep because of the mosquito in their bedroom; a sign of what awaits you when you go to bed. Especially in the summer, mosquitoes can be a real nuisance. And yes, the females are the ones that bite, because they need blood to produce good eggs. Male mosquitoes can’t bite.

But what helps against mosquitoes and what doesn’t? We will tell you more about the mosquito and what you can do to protect yourself and your family against common mosquitoes and more exotic mosquitoes like the malaria mosquito.

 

Mosquitoes can smell humans and animals

Mosquitoes can smell you from about 50 metres and 1 in 10 people have an attractive smell to female mosquitoes, particularly pregnant women. This is genetically determined, so there’s not a lot you can do about it. Mosquitoes are attracted to the carbon dioxide and lactic acid in the sweat of people. So, the more active you are, the greater the chance that mosquitoes will know where to find you and attack.

Female mosquitoes lay their eggs in stagnant water. It is always a good idea to check whether there are any places with stagnant water in and around your house or caravan, like flower trays and pots, rain barrels and small puddles. The chances are that they will contain mosquito larvae that will be fully-grown mosquitoes in a few days.

 

What helps to fight mosquitoes?

There are a few precautionary measures you can take to reduce the chances to be bitten by a mosquito.

  • Install insect screens on window and door frames to keep out mosquitoes.
  • Check crawling spaces to ensure there is no stagnant water.
  • Make sure there are no small puddles of water around the house (flower pots, buckets, etc.).
  • Check the (bed)room for mosquitoes, after installing insect screens or closing the windows.
  • Sleep under a mosquito net.
  • Apply Care Plus Anti-Insect Natural to exposed skin and the outside of your duvet cover or sheet.

There are certain substances that mosquitoes hate. DEET has been around for about forty years and has been proven to be the most effective protection against mosquito bites. Insect repellents containing 30% DEET provide about 5 hours of protection from mosquitoes. For children over two months of age, you can use concentrations with 10% or less DEET or Anti-Insect Natural without DEET. Always read the instructions on the packaging. Use in moderation, do not apply or spray on or near open skin, eyes, mouth, nose, under your clothes or near food. Wash your hands thoroughly after application.

As far as we know, DEET is the only substance that has a strong insect repelling effect on mosquitoes. Previously, it was assumed that its effectivity is based on confusing the odour sensors of the mosquito: the insect would no longer detect human presence. However, research shows that mosquitoes do smell the substance and try to avoid it. And a more recent study shows that DEET does disturb the functioning of odour receptors. This study shows that DEET only has a repellent effect at high concentrations. At lower concentrations, the repellent effect had disappeared, but there was still a striking difference between the number of insects on a prey treated with DEET and an untreated prey.

 

What does not help to repel mosquitoes

Over the years, all sorts of products have appeared on the market that are said to keep mosquitoes at bay: scented candles, vitamin B, Marmite, high-frequency devices, and there are probably a few others. Unfortunately, these products do not help to repel mosquitoes, although some resources are persistently passed on as tips.

 

What kind of mosquitoes are there?

A mosquito has a small, thin and fragile body, six thin legs, usually, two spring-like antennas used to detect odour and a small head with the often visible sucking muzzle. There are species that grow a little bigger, but these always have an elongated build and usually dangly legs. However, some mosquitoes, such as the midges, have a more fly-like build. They are also called sand flies.

 

How long does a mosquito live?

An adult mosquito lives for about 1 to 2 months. A mosquito is born from an egg. The mosquito eggs are laid in water or moist soil and after a few days the eggs hatch. The larvae that hatch from these eggs live in water or in moist soil, such as lakes, ditches, ponds, swamps and stagnant water under or on buildings. The larval stage lasts from a few days to a few weeks, after which the larvae of the mosquitoes enter the pupal stage.

This pupal stage lasts 1 to 7 days. The fully-grown mosquito (image) emerging from the pupa takes its first flight after about an hour. The mosquito lives about 1 to 2 months. The females sometimes hibernate in cellars, hollow trees or other sheltered places. The process from egg to mosquito often takes just two weeks.

 

An adult mosquito lives for about 1 to 2 months.

All mosquitoes have a sucking muzzle, but the vast majority of species can’t bite. The mosquitoes that bite belong to different families, of which the biting mosquitoes (Culicidae) are undoubtedly the best known. Species from this family include the malaria mosquito (genus Anopheles) which is indirectly responsible for more than one million human deaths each year. Other mosquitoes can also cause nuisance, although they cannot bite. Examples are crane flies whose larvae affect the lawn, moth flies that can pop up massively in the event of a burst sewage system and gnats that can occur in giant swarms. The vibration of the wings of mosquitoes produces a buzzing sound that is often perceived by people as a nuisance.

Mosquitoes live off plant juices like nectar. The two wings are folded behind the back at rest and the rear pair of legs is longer in many species and stick backwards at rest. This is what a mosquito does to observe any coming enemies; instead of seeing the enemy, the mosquito feels the air swirls with the hind legs and quickly flies away in the event of danger.

Biting mosquitoes are the best-known mosquitoes and are actually innocent insects that live on nectar. Yet, they are known to humans because they suck blood, at least the females during the production of eggs. In humans, this usually results in a red itchy bump, but stinging mosquitoes can also do a lot of damage because of the diseases they can spread, such as the notorious West Nile disease. In tropical areas, mosquitoes often spread deadly diseases (including malaria) on a large scale, killing millions of people every year. Mosquitoes can also transmit various diseases to animals. Bird and livestock farmers can suffer enormous economic damage as a result.

Mosquitoes can transmit diseases

Stinging and biting insects are not only annoying but also dangerous in some cases. They can transmit infectious diseases or cause an allergic reaction. Care Plus® products reduce insect bites and nuisance. This reduces the risk of malaria ((sub) tropical destinations), zika (an advancing disease, especially dangerous for pregnant women), yellow fever (Tropical Africa, South America) and dengue fever. Or use mosquito-repelling products that are suitable for small children or in case of hypersensitivity to DEET.

 

Malaria

Malaria or swamp fever is an infectious disease caused by single-celled parasites of the genus Plasmodium belonging to the Sporozoa. The parasite is transmitted to humans by malaria mosquitoes.

The World Health Organisation estimates that between 500,000 and 1,000,000 people die of malaria each year, mostly in Africa of which the vast majority are children under the age of 5. Around 40% of the world’s population lives in areas where malaria occurs. 20% of infant mortality in Africa can be attributed to malaria.

Pregnant women are at high risk of dying due to malaria complications, but there is also a risk of miscarriage or premature birth. And there is the risk of anemia in women and, as a result, babies with too low a birth weight.

 

Dengue

Dengue, also known as dengue fever, is a tropical infectious disease caused by the dengue virus. The symptoms include fever, headache, muscle ache, and joint pain, and a characteristic rash similar to that of measles. In a small proportion of cases, the disease develops into the life-threatening dengue hemorrhagic fever with bleeding, low platelet count and blood plasma leakage, or to dengue shock syndrome, which involves dangerously low blood pressure.

Dengue is transmitted by different species of mosquitoes of the genus Aedes, mainly by the Aedes Aegypti (dengue mosquito). The virus has five different types; infection with one type usually gives lifelong immunity to that type, but only short-term immunity to others. Subsequent infection with a different type increases the risk of severe complications. Because there is no vaccine, prevention mainly means that the habitat of the mosquitoes is restricted, their number is reduced and with it, the chances of being bitten. Approval of the EMA for Dengvaxia (Sanofi) is expected in December 2018, but only for people who have already been infected with the dengue virus.

The treatment of acute dengue is supportive in nature. In light or medium cases, rehydration is provided by drinking or intravenously. In more serious cases, liquids are administered intravenously and through blood transfusion. The number of dengue cases has risen sharply since the 1960s to around 50-100 million infections per year. Early descriptions of the condition date from 1779, and its viral cause and transmission were discovered by the early 20th century. Dengue has become a global problem since the Second World War and is endemic in more than 110 countries. Apart from eliminating mosquitoes, work is ongoing on a vaccine, as well as medication targeted directly at the virus.

 

Zika

The zika virus is a flavivirus that causes the disease zika fever. The virus is mainly transmitted by female mosquitoes. Zika fever is generally a mild condition without any treatment. The disease often resolves itself. However, there are indications that infection with the virus can have serious consequences for human health, in particular for the fetus. As a result of the virus, the child may develop microcephaly, a skull size that is too small with major consequences for further development.

The virus has been known since 1947, when the zika virus was discovered on a rhesus monkey in Zika forest in Uganda. The virus owes its name to the forest in which it was discovered.

Five cases were detected in Germany between October 2015 and January 2016. As far as we know, these have been the first cases in Europe. On 4 February 2016, the virus was diagnosed in a pregnant woman in northeastern Spain who had previously been in Colombia.

On 6 May 2016, a baby was born in Spain from a woman infected with the Zika virus, who was showing birth defects (microcephaly). It was the first concrete case in Spain where a baby was born with such abnormalities that are most likely related to the virus.

 

Yellow fever

Yellow fever is an infectious disease caused by the yellow fever virus that is spread by mosquitoes. Up to 50% of those infected dies when the disease is not treated. The disease only occurs in sub-Saharan Africa (approx. 180,000 cases per year) and South or Central America (approx. 20,000 cases per year). An estimated 84,000 to 170,000 people are infected with the yellow fever virus every year, of which around 60,000 die. In Africa and South America, 900 million people are at risk of becoming infected with yellow fever. Vaccination is the most important preventive measure to combat the disease. The yellow fever vaccine is safe, affordable and very effective. The vaccine probably offers lifelong protection against yellow fever.

The yellow fever virus belongs to the flaviviruses but was previously incorrectly classified as togaviruses. The yellow fever virus is a single-stranded RNA virus that is 35-45 nm in size. Not all mosquitoes can transmit yellow fever viruses. In Africa, it usually concerns the Aedes aegypti or Aedes africanus, in South America, they are often mosquitoes of the genus Haemagogus. The virus enters the body through the salivary glands of the infected mosquito and infects lymphocytes. The virus then spreads to the rest of the body via the regional lymph node stations. Mosquitoes that sting an infected monkey or human become contagious after 2-3 weeks.

Every year, a few percents of the local population in an area with a lot of transmissions can become infected with the yellow fever virus. In young adults in those areas, antibodies to yellow fever can be found. In the UK, no cases of yellow fever have been reported. The yellow fever virus is found in tropical and subtropical areas of South America.

  3. Do not touch animals. Dogs, cats, bats and monkeys can be infected with rabies.

Wash your hands

Vaccinations provide good protection, but not from all infectious diseases. Good personal hygiene is your best weapon in the fight against bacteria! This starts with washing your hands. Do this often and thoroughly. In any case, wash your hands and wrists before cooking, eating and after visiting the toilet or use Care Plus Soap Leaves. Rub these perfumed soap leaves between your hands with little water and they will be clean and fresh in no time at all. Dirty nails? Clean them with a brush! Dry your hands with something very clean, like a paper towel. Or keep them under hot air blower (do not touch!)

Effective for cleaning your hands: a good hand gel, like Care Plus Pro Hygiene Gel. Handy for on the road, because Pro Hygiene Gel can be used without water.

Safe drinking water

Drinking tap water in Western Europe and North America is not usually a problem. In other regions, you need to take precautionary measures to make drinking water safe. Water can be contaminated. Microorganisms can cause infectious diseases, especially in the gastrointestinal tract. Diarrhoea is the most common problems.

There are several methods to make drinking water safe:

  1. Disinfecting with Care Plus Hadex®, a drinking water disinfectant approved by the Dutch government (kills bacteria and viruses).
  2. Microfiltration (removes protozoa and bacteria, depending on the filter).
  3. Boiling the water (kills all microorganisms)
