up to 8 hours Formulated with 25% DEET - provides up to 8 hours of protection against mosquitoes. OFF! ® Deep Woods® Insect Repellent V provides long-lasting protection against biting insects such as ticks, mosquitoes, black flies, sand flies, chiggers, and gnats.

The bug spray works like you'd expect, and last much longer due to the higher deet. Unfortunately, I now know deet does not work with deer/horse flies, but this product deters nearly all other flying insects. Down side is that due to the higher deet level, your mouth goes numb if you get any spray on it.

OFF! ® Clean Feel provides non sticky & fragrance free protection from mosquitoes, ticks, and biting flies. Formulated with Picaridin, feels good on skin, & up to 8 hours of mosquito protection, so feel confident using OFF!

® Deep Woods® Insect Repellent V (Tick) provides long-lasting protection against ticks (including the ticks that may cause Lyme Disease), mosquitoes and biting flies, stable flies, black flies and sandflies. Also repels chiggers, fleas, gnats, no-see-ums so you can enjoy the outdoors uninterrupted.

For reference, a repellent containing 15% DEET typically provides up to six hours of mosquito protection, while a repellent with 25% DEET typically provides up to 8 hours of mosquito protection.

How long will pesticides last after application? A typical pest control application will last around 90 days. If outdoor applications see consistent or heavy rainfall, they efficacy may be affected and will last about 60 days. Pesticides used to treat flying insects like mosquitoes or flies will last around 30 days.

The human health risk assessment concluded that there are no risks of concern because no toxic effects have been identified when used as a dermally applied insect repellent, and there is no dietary or occupational exposure for DEET.

Deep Woods® Dry Insect Repellent protects against biting flies, gnats, and chiggers too. MYTH: Children should not use products containing DEET. FACT: When applied correctly, DEET is appropriate for use on children. Products containing DEET can be used on children.

Insect repellent can be used as young as 2mo of age, if exposure to insects is unavoidable. We recommend Deep Woods Off, which is available in a spray form or in towelettes. The towelettes are especially helpful for babies and young children, as they allow more direct application and less inhalation of the product.

around 20 to 30% Concentrations of DEET that might prevent tick attachment may not deter a tick from walking across the skin to unexposed and untreated areas. For blacklegged ticks, DEET concentrations around 20 to 30% applied to clothes are about 86-92% effective in preventing tick bites in earlier studies.

Sunscreen needs to be reapplied often, while DEET should not be used more than once a day. DEET concentrations higher than 30% are not more effective and the chemical (which is absorbed through the skin) in high amounts can be toxic. Follow the directions on the label.

Apply only as often as the label recommends. Usually, that means only once a day. When you return indoors, shower or wash your skin with soap and water. Wash clothing to remove any remaining DEET.
