The Dirt on Personal Insect Repellents

We’ve all become more aware of diseases carried by ticks, mosquitos and other bug pests. Certain pesticides and repellents offer effective ways to protect you and your family.

“Using insect repellent regularly is the first line of defense from bug bites and the insects, like mosquitoes and ticks, that may carry serious diseases,” says Kelly M. Semrau, senior vice president for global corporate affairs, communication and sustainability at SC Johnson. “Families should plan ahead for extended periods outdoors by selecting the right personal insect repellent to fit their activities.” Using tick repellent isn’t all you can do to protect yourself. These smart devices ward off bugs.

Here’s how to win the war on pests:

But over the years some misconceptions cropped up about these products. Learn the truth behind these common myths and safely protect your family.

Myth: DEET and Picaridin are Unsafe Chemicals

Developed by the USDA for use by the U.S. Army in mosquito infested areas, DEET has been available to the consumer since 1957 and is the most commonly used ingredient in repellents. Data has proven that it’s safe when used properly. Likewise, its counterpart picaridin has been evaluated for safety, according to the World Heath Organization and the CDC. Follow the directions and use repellents with these chemicals as they are intended. Here’s what to do if you find a tick in your house.

Myth: Repellent Doesn’t Work

According to SC Johnson, “Every type of product has specific instructions for application, so always consult and follow the directions on the product label before applying.” Remember, like sunscreen, you have to reapply for the best results. Plus, do mosquito bracelets, clip-ons and patches actually work?

Myth: DEET and Picaridin Kill Ticks and Mosquitoes

No, they don’t. DEET and picaridin are repellents that only keep the bugs away, and you have to reapply for them to keep working. Here’s how to avoid deer ticks.

Myth: The Higher Percentage of an Active Ingredient, the Better Protected I am

Actually, the higher percentage only lets you know how long it will last. According to SC Johnson, “It is important to consider the activities that will be performed, the length of time you will be outside and the type of insects you may come in contact with to determine the concentration of active ingredients needed when buying a repellent.” Again, read the label and follow the instructions. If you do get bit, here are 10 easy home remedies for bug bites.
