Whether you’re simply going on a walk around the block or a camping trip out in the wilderness, connecting with the great outdoors is a wonderful escape from everyday life.
Unfortunately, insects can quickly sour those plans. Among the worst insects you can encounter in the summer months, mosquitoes and ticks are bound to top the list.
Not only do these pests leave painful bites, but several mosquitoes and ticks in Pennsylvania can spread dangerous diseases, such as Lyme’s Disease, West Nile Virus, Yellow Fever, and more. While rare, it’s generally better to be safe than sorry, especially when it comes to ticks.
DEET is one of the most popular over-the-counter products designed to repel insects like ticks and mosquitoes. This popular spray is used by everyone from hikers to families looking to enjoy a nice barbecue in their backyard.
But is DEET effective and, more importantly, is it safe? We’ll discuss the benefits and potential risks of DEET and alternatives to repel ticks, mosquitoes, and other insects safely.
What is DEET?
DEET, or N, N-Diethyl-m-toluamide, is a substance found in insect repellents. Developed by the US Army in 1946, it acted as a safeguard for the military in insect-infested areas.
DEET is especially good against mosquitoes and ticks, which can carry devastating diseases. However, there has been some debate on how safe the repellent is.
Numerous tests have been conducted on the effects of DEET, but the results show negligible adverse effects. In fact, there are no definitive results that show that DEET is unsafe when used correctly.
When used properly, the repellent can keep insects from landing on you by confusing their senses or by making it difficult to land. DEET is not the same substance as DDT, which was banned in the US in 1972.
Also, the percentage of DEET in a repellent determines the length of time you are protected. If you use the proper amount and apply it according to the directions, DEET can work wonders.
Is DEET Safe?
Misusing DEET has led to a bad reputation. The possibility of DEET poisoning is incredibly low and cases of toxicity are mild.
After research by the EPA’s office, there’s no conclusive evidence that DEET has any long-lasting effects. It also doesn’t affect the environment and breaks down in the sunlight once sprayed. The key is to use the appropriate concentration and follow the instructions. So, why use DEET at all?
The Benefits of DEET
The biggest positive point DEET has is its ability to deter and repel mosquitoes. The repellent messes with the mosquitoes’ antennae and mouthparts that seek out lactic acid and carbon dioxide. Since these flying insects are considered one of the most dangerous creatures to humans, having protection is imperative.
In addition, DEET repels several other flying insects, including biting flies, gnats, and chiggers. The repellent also wards off several other blood-sucking insects like ticks, fleas, and leeches.
1. Protects Against Mosquitoes
Ideally, DEET repels mosquitoes, which are dangerous and carry terrible, life-threatening diseases, like West Nile, yellow fever, and Zika virus. There are very few ways to protect yourself from mosquitoes short of eliminating standing water on your property. However, that won’t protect you everywhere else – and those flying terrors are everywhere.
2. Repels Ticks too!
Mosquitoes aren’t the only dangerous pests that can be hard to repel. Ticks can be harmful, too.
They carry devastating diseases such as Lyme and Rocky Mountain Spotted Fever, and they can be difficult to spot on your own body. Once they latch and become engorged, they can transmit the disease. DEET can help keep ticks off your skin.
3. Guards Against Additional Insects
An insect doesn’t have to be disease-ridden to be difficult to keep at bay. Sometimes, the most annoying insects can be resistant to normal repellents. DEET can help protect against gnats, fleas, biting flies, chiggers, and leeches. With the right repellent, you can protect against all these nasty pests.
4. Easy to Find
You don’t have to go on a deep dive on the internet or a journey to a specific store to find a repellent that includes DEET. In fact, there are several over-the-counter options that are extremely easy to obtain.
These repellents are EPA registered. Over 30 companies have these repellents, and there are over 120 different products containing DEET. Whatever way you want to apply it, these applicants come in liquids, lotions, sprays, and other options for direct application.
5. Safe to Use
Products with DEET are safe to use and are remarkably effective when used properly. There are no toxic side effects, and it is safe to apply to children. If you are looking for protection outdoors, it’s an easy solution. Just be sure to follow the instructions.
Applying DEET Safely
If you are heading outside and plan on applying repellent featuring DEET, be sure you follow the instructions. When applying, you must do the following:
- Read the label and follow the product instructions.
- Don’t apply on open or irritated skin.
- Keep away from your nose, eyes, and mouth.
- Don’t oversaturate – a little goes a long way.
- Don’t use it under clothes.
- Wash the spray off after going indoors.
- Apply in open, well-ventilated areas.
- Don’t spray on your face.
- Help small children apply it, but don’t place it on their hands.
Follow these instructions properly, and DEET repellents can add a layer of protection against dangerous and annoying insects.
DEET Alternatives
While DEET is one of the most effective insect repellents available, some people prefer alternatives due to skin sensitivity, environmental concerns, or personal preference. Luckily, several other options offer solid protection against insects:
- Picaridin: A popular alternative to DEET, picaridin is odorless, non-greasy, and just as effective at repelling mosquitoes and ticks. It’s also considered safe for children and doesn’t damage plastics or fabrics.
- Oil of Lemon Eucalyptus (OLE): Derived from a natural plant source, OLE is a botanical-based repellent that’s been proven to repel mosquitoes effectively. Look for products containing at least 30% OLE for best results.
- IR3535: Found in some skin-friendly repellents, IR3535 offers moderate protection against mosquitoes, ticks, and biting flies. It’s often found in combination with sunscreens or moisturizers.
- Natural essential oil blends: Some repellents use ingredients like citronella, peppermint, tea tree oil, or geranium. While these are more eco- and skin-friendly, they tend to wear off quickly and need frequent reapplication. They’re best for short-term or low-risk outdoor activity.
- Physical barriers: Wearing long sleeves, pants, hats, and using permethrin-treated clothing or gear can also help deter insect bites without using topical repellents at all.
No matter which option you choose, always check the label for safe use, especially when applying products to children or using them for long periods outdoors.
