What Is DEET (PDF)
DEET is the active ingredient in many insect repellent products. It is WHAT used to repel biting pests such as mosquitoes and ticks, which may carry Lyme disease. Every year, approximately one-third of the U.S. IS population uses DEET, which is available in a variety of liquids, lotions, DEET sprays, and wrist bands. HOW DOES DEET WORK? DEET is designed for direct application to human skin to repel insects, rather than kill them. There are approximately 140 products containing DEET currently registered with the U.S. Environmental Protection Agency (EPA). IS DEET SAFE FOR CHILDREN? The American Academy of Pediatrics (AAP) Committee on Environmental Health has updated their recommendation for use of DEET products on children in 2003, citing: “Insect repellents containing DEET 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.” AAP recommends that repellents with DEET should not be used www.dupagehealth.org/ftb on infants less than 2 months old. Parents should choose the type and concentration of repellent to be used by taking into account fightthebitedupage the amount of time that a child will be outdoors, exposure to mosquitoes, and the risk of mosquito-transmitted disease in the @fight_the_bite area. If you are concerned about using repellent products on children you may wish to consult a health care provider for advice or contact the ABATEMENT National Pesticide Information Center (NPIC) through their toll-free PARTNER LOGO number, 1-800-858-7378 or npic.orst.edu From http://www.cdc.gov/ncidod/dvbid/westnile/qa/insect_repellent.htm DUPAGE COUNTY HEALTH DEPARTMENT What IS DEET 1 USE DEET PRODUCTS SAFELY: WHAT Do not apply over cuts, wounds, or irritated skin. -
Helpline Hot Topic June 2019
Helpline Hot Topic for June 2019 Mosquito Repellent Plants By Cynthia Zimmerman “It’s not so much how busy you are, but why you’re busy. The bee is praised; the mosquito is swatted.” - Marie O’Connor While I’ve been busy working in my vegetable garden recently, I unfortunately have found that mosquitoes are already busy dining on me. I happen to be one of those people that if there is a mosquito anywhere near-by, it will make its presence known by leaving me with multiple bites. One of the things I’ve noticed the past few years is that when I pick produce in my garden, particularly tomatoes, I always come away with mosquito bites. I was told some years ago that mosquitoes like to retire to the interior of plants to rehydrate during the day, so every time I stick my arm in the tomato plant to pick a tomato, I offer up prime feasting. I hate having to drench myself in insect repellent in order to sit on my patio or spend time in my garden plus I discovered some years ago when I lived in North Carolina at the southern end of the Dismal Swamp that even military grade repellents don’t work very well for me. This has led me to explore the possibility of using plants as repellents. As I’ve searched I find that little has been done in the way of scientific research or studies as to the efficacy of plants to repel insects. Still there are many plants that are purported to be useful in controlling certain insect populations. -
Mosquitoes Are Still Lurking – Protect Yourself This Fall (From August 2018 Newsletter)
Mosquitoes are still lurking – protect yourself this fall (From August 2018 newsletter) Even though summer is waning, the risk of mosquito bites is still high. We have had a particularly hot and humid summer, which creates an excellent breeding environment for mosquitoes. Besides being uncomfortable, mosquito bites can lead to diseases such as Zika and West Nile disease. Read on to learn how to best protect yourself. What works – bug repellent: Wearing bug repellent is one of the best ways to avoid mosquito bites. There are a myriad of insect repellent products on the market. Some ingredients work better than others. The following are approved by the Centers for Disease Control (CDC) and the Environmental Protection Agency (EPA) for mosquito (and also in some cases, tick) protection: • DEET: DEET is one of the most common and effective insect repellents. It is safe for adults and children older than two months. • Picardin: This compound is designed to be used on clothing. Do not use directly on your skin. • Permethrin: This repellent, derived from the pepper plant is an excellent DEET alternative. • IR3525 • 2undecanone • Lemon eucalyptus oil: Note: Do not use this on children under three years old. Always use EPA registered repellents. Look for the EPA registration number on the back label. Wear it right: For the most part insect repellent is very safe. But it is important to not overexpose yourself. Follow these tips: • The correct way to use repellent is to apply it after sunscreen. Sunscreen works on the deeper layers of skin, while bug repellent works on the top layer. -
West Nile Virus Insect Repellents and DEET Tips: Deciding on Their Use
West Nile Virus Insect Repellents and DEET Tips: Deciding on Their Use Chemical repellents are effective at reducing bites from insects that can transmit disease. But their use is not without risk of health effects, especially if repellents are applied in large amounts or improperly. This information will help you decide when and if a repellent is right for you. ABOUT REPELLENTS Two active ingredients found in repellents are DEET (the label might say N,N-diethyl-m-toluamide) and permethrin. Most insect repellents contain one of these active ingredients. DEET comes in many different concentrations, with percentages as low as five percent or as high as 100 percent. In general, the higher the concentration, the higher the protection, but the risk of negative health effects goes up, too. Use the lowest concentration that you think will provide the protection you need. Products with up to 30 percent DEET will provide adequate protection under most conditions. The American Academy of Pediatrics recommends that repellents used on children two years -12 years of age contain no more than 10 percent DEET. DEET has been widely used for many years. Skin reactions (particularly at concentrations of 50 percent and above) and eye irritation are the most frequently reported health problems. Some reports of central nervous system problems, more frequently reported in children than adults, range from slurred speech and confusion to seizures and coma. Cases of serious reactions to products containing DEET have been related to misuse of the product, such as swallowing, applying over broken skin, and using for multiple days without washing skin in between. -

A eucalyptus-based insect repellent (PMD) with the principal active ingredient p-men- thane-3,8-diol was evaluated in the field in comparison with deet. In human landing catches in Tanzania, 3 formulations of PMD were tested against Anopheles gambiae and An. funestus.

General Fact Sheet Deet
DEET GENERAL FACT SHEET What is DEET DEET is an insect repellent that is used in products to prevent bites from insects such as mosquitoes, biting flies, fleas and small flying insects. DEET is a colorless liquid that has a faint odor and does not dissolve easily in water. DEET was developed by the U.S. Army in 1946 for protection of soldiers in insect-infested areas. Insect repellents containing DEET have been used by the general public in the United States since 1957. What are some products that contain DEET DEET has been used in a number of insect repellent products including liquid sprays, lotions, and sticks. It has been estimated that about 30% of the U.S. population uses one or more products that contain DEET every year. If any exposures occur, be sure to follow the First Aid instructions on the product label carefully. For additional treatment advice, contact the Poi- son Control Center at 1-800-222-1222. If you wish to discuss a pesticide problem, please call 1-800-858-7378. How does DEET work Scientists do not know exactly how DEET works on all insects. Some insects sense people by detecting the chemicals from our bodies and in the air that we breathe out. It has been shown that insects exposed to DEET are not able to locate a person or animal because they cannot detect them. How might I be exposed to DEET There are four ways that people can be exposed to chemicals: contacting their skin, contacting their eyes, breathing them in, or eating them. -

For more information, call the CDC Information Center at 1-800-232-4636. This fact sheet is one in a series of summaries about hazardous substances and their health effects. It’s important you understand this information because this substance may harm you. The effects of exposure to any hazardous substance depend on the dose, the duration, how you are exposed, personal traits and habits, and whether other chemicals are present. HIGHLIGHTS: Exposure to DEET occurs mainly by dermal contact from intentional application to the skin and clothing of consumer products containing DEET. Unintentional inhalation and oral exposure can also occur during normal use. The risk of health effects due to exposure to DEET following recommended application procedures appears to be quite low. DEET has been found in at least 2 of the 1,699 National Priorities List sites identified by the Environmental Protection Agency (EPA). • Workers involved in the manufacture of DEET or of What is DEET? commercial products containing DEET can be exposed to higher levels of this substance.

An Investigation of Deet- Insensitivity in Aedes Aegypti
AN INVESTIGATION OF DEET- INSENSITIVITY IN AEDES AEGYPTI NINA STANCZYK, BSc. Thesis submitted to the University of Nottingham for the degree of Doctor of Philosophy July 2011 1 Abstract N,N-Diethyl-m-toluamide (DEET) is one of the most effective and commonly used mosquito repellents. However, during laboratory trials a small proportion of mosquitoes are still attracted by human odours despite the presence of DEET. In this study behavioural assays identified Aedes aegypti females that were insensitive to DEET. The selection of either sensitive or insensitive groups of females with males of unknown sensitivity over several generations resulted in two populations with different proportions of insensitive females. Crossing experiments showed the ‘DEET-insensitivity’ trait to be dominant. In addition to the finding of heritable DEET-insensitivity, unselected culture mosquitoes were shown to change their sensitivity to DEET after brief pre-exposure to the repellent. Female mosquitoes that were sensitive to DEET when first tested became insensitive when retested. Electroantennography showed that mosquitoes that were insensitive to DEET had a reduced response to DEET compared with mosquitoes that were sensitive to it. This was the case both for culture mosquitoes displaying insensitivity to DEET after brief pre-exposure to it, and for the sensitive and insensitive lines selected for several generations. Single sensillum recordings of the selected lines identified DEET-sensitive sensilla in the sensitive line that did not respond to DEET in the insensitive line. This study suggests that behavioural insensitivity to DEET in Ae. aegypti is a genetically determined dominant trait, which can also be temporarily induced by pre-exposure, and resides in changes in sensillum function.
