What You'll Learn
DEET melts plastic
DEET, or N, N-Diethyl-meta-toluamide, is a chemical compound that is highly effective as an insect repellent. It was developed by the U.S. Army in 1946 and has been a popular choice for bug spray ever since. While DEET is safe for human use and does not harm natural materials such as cotton and wool, it can have detrimental effects on certain synthetic materials, particularly plastics.
DEET has been found to soften and melt certain types of plastics. This is a significant concern for those who use products containing DEET outdoors, as many items of outdoor gear are made with synthetic materials. For example, hikers and campers often use tents, backpacks, and clothing made from polyester and nylon, both of which are types of plastic that DEET can damage. In addition, DEET can harm plastic watch crystals, camera equipment, and the plastic cases and screens of electronic devices.
One of the reasons DEET is so effective at repelling insects is that it acts as a solvent. Unfortunately, this also means it can dissolve or soften plastics. This property of DEET has resulted in numerous reports of damaged gear and equipment. For instance, a user on Reddit reported that a bottle of DEET spilled in a tackle box and melted the plastic, causing the tackle to spill everywhere. Another user on a photography forum shared that they saw someone leave a perfect fingerprint in the top plate of their camera due to the softening effect of DEET.
To avoid these issues, it is crucial to exercise caution when using products containing DEET. It is recommended to be mindful of the surrounding items and surfaces when applying bug spray and to avoid spraying it directly onto plastic items. Additionally, washing hands thoroughly after applying DEET is essential to prevent accidental transfer to camera equipment, phones, or other electronic devices.
While DEET is effective at repelling insects, there are alternative products available that are safer to use around plastics. One such alternative is Picaridin, which is effective as an insect repellent, safe to use around plastics, and less likely to cause negative health effects.

DEET eats polyester
DEET, or N, N-Diethyl-meta-toluamide, is a chemical compound that is highly effective as an insect repellent. It was developed by the U.S. Army in 1946 and has been a popular choice for those seeking to avoid pesky bugs and their bites. While DEET is safe for human use and does not harm natural materials such as cotton, wool, aluminium, or steel, it has been known to react with certain synthetic materials, particularly plastics.
DEET is known to cause damage to some plastics and synthetic materials. This includes items made of polyester, rayon, spandex, nylon, and other plastic-based materials. The chemical structure of DEET can react with the polymers in these synthetic materials, causing them to break down or soften. This can result in visible damage, such as warping or melting, and can compromise the integrity of the affected items.
One of the most commonly affected items is polyester, a synthetic fabric used in a variety of clothing and gear, especially for outdoor activities like hiking. DEET has been reported to eat through polyester, causing damage to clothing and equipment. This can be a significant concern for hikers and outdoor enthusiasts who rely on their gear to be durable and long-lasting.
However, the extent of damage caused by DEET on polyester seems to vary. Some users report no issues with using DEET on their polyester clothing, while others have noticed significant deterioration. It is important to note that not all plastics are created equal; different types of plastics have different chemical compositions and properties, which can affect their reaction to DEET.
To minimise the risk of damage, it is recommended to avoid applying DEET directly to polyester items. Instead, consider using alternative insect repellent products that are known to be safe for use on plastics and synthetic materials, such as Permethrin or Picaridin. These alternatives can be sprayed or soaked onto clothing and gear without causing the same type of damage as DEET. Additionally, always read the instructions on any insect repellent product to ensure proper and safe usage.

DEET dissolves plastic
DEET, or N, N-Diethyl-meta-toluamide, is a chemical compound that is highly effective as an insect repellent. It was developed by the U.S. Army in 1946 and has been widely used ever since. While DEET is safe for human use and does not have any known negative effects on health or the environment, it is important to exercise caution when using it around certain materials, especially plastics.
DEET has been found to dissolve some types of plastics. This is because DEET acts as a solvent, breaking down the chemical bonds in plastic materials. The softer the plastic, the more susceptible it is to the effects of DEET. This includes items made of polyester, nylon, spandex, rayon, and other synthetic fabrics. DEET can also damage or dissolve waterproof coatings and membranes, such as those found on rain gear and outdoor equipment.
The impact of DEET on plastics can result in permanent damage. For example, it can melt plastic watch crystals, dissolve plastic screens on electronics, and render camera equipment unusable. It is crucial to be cautious when applying insect repellents containing DEET to avoid accidental contact with these items. This includes being mindful of not only the application process but also the storage and transportation of DEET products to prevent leaks and spills.
Additionally, DEET can affect plastic items in direct contact with skin treated with DEET. For instance, a plastic strap on a pair of binoculars came into contact with skin that had been liberally treated with DEET, resulting in a chemical burn on the user's neck. This highlights the importance of being vigilant about where DEET is applied and what materials it may come into contact with.
To mitigate the risks associated with DEET and plastics, it is recommended to use alternative insect repellents, such as Picaridin or Permethrin, when there is a possibility of exposure to plastic items. These alternatives are effective at repelling insects and are safer to use around plastics and synthetic materials. It is also advisable to opt for lower concentrations of DEET, as higher concentrations do not necessarily increase repellency and may pose a higher risk of damage to plastics.

DEET is safe for humans
DEET, or N,N-Diethyl-meta-toluamide, is a chemical mixture used as an insect repellent. It was developed by the U.S. Army in 1946 to protect soldiers from mosquitoes in World War II. Today, it is used by over 200 million people worldwide to ward off insects like mosquitoes, fleas, ticks, and flies, thus preventing insect-borne illnesses such as Lyme disease, West Nile virus, and Zika virus.
Despite its effectiveness, concerns have been raised about the safety of DEET for human use. Some people experience skin irritation, rashes, or eye irritation if it is sprayed too close to the eyes. There have also been rare reports of seizures associated with DEET, particularly in children. However, these cases typically occur when DEET products are ingested or used incorrectly, such as by applying them to cuts or irritated skin.
While there have been reports of potential carcinogenic effects, the evidence is mixed. The Department of Health and Human Services and the EPA's Office of Pesticide Programs have not classified DEET as a carcinogen. Animal studies have not found an increased risk of tumors in subjects given oral DEET or liquid DEET applied to the skin. However, a Swedish study suggested a possible link between long-term insect repellent use and an increased risk of testicular cancer in men, although the CDC criticized the study's methodology.
In addition, at least one study found that exposure to high doses of DEET during pregnancy resulted in low birth weights and severe birth defects in rodents, and similar cases were reported in humans. However, other rat studies failed to replicate these findings, and similar animal studies found no effects from DEET on pregnancy. Overall, the highest-quality research on DEET use during pregnancy is reassuring.
Experts advise that DEET is safe for humans when used as directed. The Environmental Working Group considers DEET safe when properly applied. The U.S. Environmental Protection Agency (EPA) found no "risks of concern" to people or the environment in its 2014 review of the repellent. While any chemical poses some risk, especially when misused, the incidence of adverse effects is very low compared to the estimated 100 million annual human applications of DEET.
To ensure safe use, it is recommended to test DEET on a small section of skin before full application, as individuals may react differently to skin products. When using DEET-based bug sprays, follow the instructions and apply them sparingly in well-ventilated areas to avoid inhalation. Covering up with clothing can also help minimize direct skin exposure to bug sprays and insects.

DEET alternatives
DEET, an insect repellent developed by the U.S. Army in the 1940s, is known to damage plastic and synthetic gear components. It is advised to wash hands thoroughly after using DEET and to be cautious about it coming into contact with gear. While it is widely used and considered safe by many health organizations, some people are hesitant to use it due to its strong odour, greasy feel, and potential health concerns.
- Picaridin: This is a synthetic compound developed from a plant extract of the genus Piper, which produces table pepper. It is a newer option, having been approved for sale in the United States in the 2000s after being available in Europe and Australia since 1998. Picaridin provides long-lasting protection against a wide range of insects, including mosquitoes, ticks, and flies, without the same drawbacks as DEET. It is effective at repelling insects, doesn't have an odour, and doesn't damage items. The maximum protection is provided by formulations with 20% picaridin.
- Plant-based repellents: Natural alternatives include synthesized plant oils like lemon eucalyptus oil and IR3535, which are effective against mosquitoes and some tick species. However, their protection doesn't last as long as chemical repellents, and they may not repel as many types of bugs.
- Permethrin: This insect repellent can be applied to clothing and shoes to create a powerful barrier against ticks and other insects. It is available as an over-the-counter spray or washing treatment, or you can purchase pre-treated clothing.
- Cyclic acetals and hydroxyacetals: Researchers have developed plant-based repellents with extended protection times beyond that of DEET by converting terpenoids into cyclic acetals and hydroxyacetals. These new compounds have pleasant and faint odours and are easier to dissolve in water, allowing for formulations without high concentrations of alcohol. Some are as effective as DEET and picaridin in repelling certain mosquito species.
