Best ways to repel pesky mosquitoes

Mosquito season is here, and these pesky pests have become a problem for us all, especially after the heavy rainfall in Houston and surrounding areas in July.  Dr. John Wolf, professor of dermatology at Baylor College of Medicine, shares how to keep mosquitoes at bay and what works best to repel them from your skin.

Clothing

If you plan to be outside, know that mosquitoes are most prevalent at dawn and dusk. Wear loose-fitted clothes made of lighter fabrics, long sleeves and pants.

“Wearing bright-colored clothing, cologne or perfume will attract mosquitoes to you,” Wolf said.

Protecting your property and your skin 

Mosquitoes breed in water. Be sure to empty items (pots, containers, wagons) around your home with standing water. If you have a bug zapper, Wolf says to get rid of it.

“They’re not very effective. While they may kill some mosquitoes, they actually kill a lot more useful insects like butterflies or dragonflies. The same goes for insecticide sprays.”

Some people choose to use home remedies that don’t contain chemicals to repel mosquitoes from their skin. Natural scents and plants like lavender, eucalyptus, lemon or lemongrass, cedar or citronella are commonly used, but Wolf says they may not be effective. A popular item to use is vitamin B complex, but Wolf says there aren’t any scientific studies to prove this works.

The most effective mosquito repellants contain up to 30% DEET or picaridin.

“While there is no perfect way to avoid mosquito bites, repellants with these ingredients are proven to be safe, reliable and effective. DEET, specifically, is approved for adults and children over two months,” Wolf said.

Products with up to 30% DEET can provide protection for up to 10 hours but should not be applied directly to the face. They can be irritating to the mouth, eyes and sensitive skin.

If you plan to use a repellant with DEET and sunscreen, Wolf says to apply the sunscreen to your skin first and then add the repellant.

“We don’t recommend using a product with a combination of sunscreen and a repellant with DEET. This is because, with sunscreen, you should reapply it every two to four hours. DEET should only be applied once or twice a day," said Wolf. 

Mosquito bite treatment

If you get bitten by a mosquito, Wolf recommends using a cool compress or an ice pack to reduce swelling and itching. You can also try an over-the-counter hydrocortisone lotion or cream or an antihistamine. If you have a serious reaction to a mosquito bite, go to an urgent care facility or an emergency room.
