Alaroma-IMR is a microencapsulated mosquito repellent finish that can be applied to textiles to protect people from mosquito bites and diseases. It works through direct contact repellency, keeping mosquitoes away from treated surfaces. Field tests show it is highly effective at repelling mosquitoes on polyester and poly/cotton fabrics, with up to 100% repellency.

3. What problems can be caused by mosquito bites? Ordinarily, the bites of mosquitoes and other insects are just a nuisance, although the bite may cause itching or swelling. The symptoms of an insect bite can usually be treated with over-the-counter medications. However, in rare situations, an insect bite can transmit certain diseases such as West Nile virus, St. Louis encephalitis and California (LaCrosse) encephalitis. Insect-repellent textiles are considered by public health agencies worldwide to be an increasingly important component in the fight to reduce the incidence of insect-borne infectious diseases such as malaria, West Nile virus, encephalitis, dengue fever, Lyme Disease and numerous others. Insect-borne diseases afflict hundreds of millions of people each year and represent a significant portion of overall infectious diseases, which globally rank second among all causes of death. Vaccines and therapeutic drugs have yet to be developed to treat many of these diseases, so preventive measures must be taken to control these insects and avoid contact with them .

5. Mosquito Attractants Items and activities that attract mosquitoes as a list of things to avoid or that can be used as bait to lure mosquitoes away from you. Dark Clothing Many mosquitoes use vision to locate hosts from a distance. Dark clothes and foliage are initial attractants. Carbon Dioxide You give off more carbon dioxide when you are hot or have been exercising. A burning candle or other fire is another source of carbon dioxide. Lactic Acid You release more lactic acid when you have been exercising or after eating certain foods (e.g., salty foods, high-potassium foods). Floral or Fruity Fragrances In addition to perfumes, hair products, and scented sunscreens, watch for the subtle floral fragrance from fabric softeners and dryer sheets. Skin Temperature The exact temperature depends on the type of mosquito. Many mosquitoes are attracted to the slightly cooler temperatures of the extremities. Moisture Mosquitoes are attracted by perspiration because of the chemicals it contains and also because it increases the humidity around your body. Even small amounts of water (e.g., moist plants or mud puddles) will draw mosquitoes. Standing water also allows mosquitoes to reproduce.

6. What are DEET insect repellents? DEET (N,N-diethyl-m-toluamide) is a versatile and effective insect repellent. Insect repellents containing DEET have been used for more than 40 years by millions of people worldwide to repel mosquitoes, ticks, fleas, biting flies and chiggers. These products are available in many formulations, including lotions, creams, gels, aerosol and pump sprays, and towelettes. Insect repellents can reduce the risk of mosquito and tick bites, but products containing DEET must be used properly.

9. What about using DEET repellents on children? No definitive studies exist in the scientific literature about what concentration of DEET is safe for children. No serious illness has been linked to the use of DEET in children when used according the product recommendations. The American Academy of Pediatrics (AAP) Committee on Environmental Health has recently updated their recommendation for use of DEET products on children, citing: "Insect repellents containing DEET (N,N-diethyl-m-toluamide, also known as N,N-diethyl-3-methylbenzamide) with a concentration of 10% appear to be as safe as products with a concentration of 30% when used according to the directions on the product labels."

10. What about using DEET repellents on children The AAP and other experts suggest that it is acceptable to apply repellent with low concentrations of DEET to infants over 2 months old. Other guidelines cite that it is acceptable to use repellents containing DEET on children over 2 years of age. Repellent products that do not contain DEET are not likely to offer the same degree of protection from mosquito bites as products containing DEET. Non-DEET repellents have not necessarily been as thoroughly studied as DEET, and may not be safer for use on children. Is DEET safe for pregnant or nursing women? There are no reported adverse events following use of repellents containing DEET in pregnant or breastfeeding women .

11. Indoor tests: application tests under constant conditions This procedure complies with a protocol which was developed for the Stiftung Warentest, the German equivalent of the Consumer Reports in the United States. The test rooms are air conditioned, and the number, age, and species of the mosquitoes used in the study can be controlled. This test is a good alternative field tests: More realistic than cage tests, but possible at any time and at less expense.

12. Tests of insecticide-treated textiles and surfaces The effectiveness of insecticide-treated textiles (such as bed nets, canvas, etc.) or surfaces is usually studied in standardized cone bioassays with insecticide-susceptible strains of the malaria mosquito, Anopheles gambiae . The procedure is promoted by the WHO and other international and national organizations. In the case of the evaluation of insecticides with additional repellent properties, where exposed mosquitoes might spend more time resting on the cone and not on the treated surface, alternatives such as the wire-ball test (wrapping the textile around a wire frame and introducing mosquitoes into this ball), cylinder tests (the inside of a test cylinder is covered with the textile), and other methods are often applied. Tick tests Effective protection from ticks, the carriers of Lyme disease (borreliosis) and tick-borne encephalitis (TBE), is becoming increasingly important. This is why, in collaboration with tick specialists, we also offer efficacy tests with ticks. We cater for all requirements – from basic in vitro lab tests (moving object assays) to lab tests with human subjects and field studies.

13. Cone test of an insecticide-treated textile. Mosquitoes (usually malaria mosquitoes, Anopheles gambiae ) are introduced into a standardized cone for a defined time span, then removed and transferred to small cages to determine the knock-down and knock-dead rates.

14. F ield tests: the most meaningful evidence for the efficacy of a treated textile: F ield studies are the ultimate verification of the performance of your product. The most realistic conditions deliver the most meaningful results. We perform field tests in Europe, North America, Brazil, and Australia. Testing repellent-treated textiles in the field near Regensburg: The location in which these tests were performed is especially rich in the floodwater mosquitoes Aedes vexans and Aedes/Ochlerotatus sticticus . Ae. vexans is distributed almost world-wide, Ae./Oc. sticticus in Europe, northern Asia, and North America.
