Does Mosquito Spray Kill Ticks?

Mosquitoes 2

Ticks and mosquitoes are not just annoying pests, but they are carriers of diseases that can pose serious health risks. Many people use mosquito sprays to keep these pests at bay. However, a question that frequently comes up is, “Does mosquito spray kill ticks?”


Mosquito sprays containing DEET or picaridin can repel ticks, but their effectiveness is usually less than against mosquitoes. Therefore, while mosquito sprays can provide some protection, specialized tick sprays or treatments are generally more effective in preventing tick bites and tick-borne diseases.

The Short Answer

The short answer is that mosquito sprays containing DEET or picaridin can be effective in repelling ticks, but their effectiveness may be less than against mosquitoes.

The Science Behind It

Mosquito sprays work by using active ingredients that repel or kill mosquitoes. The most common active ingredients include DEET (N,N-diethyl-meta-toluamide), picaridin, oil of lemon eucalyptus, and IR3535. These ingredients work by making it difficult for biting insects like ticks and mosquitoes to detect humans, thus reducing the chances of bites and the transmission of tick-borne diseases.

However, the effectiveness of these ingredients in repelling ticks is usually less than against mosquitoes. DEET, for example, can repel ticks for around eight hours compared to 12 hours against mosquitoes. Another effective repellent against ticks is picaridin, which can protect against mosquitoes and ticks for 3 to 4 hours when used at a concentration of 5%.

The Proper Application

To properly apply mosquito spray for optimal tick extermination, focus on applying the spray on grassy and bushy areas, particularly in shady and moist spots. Follow the product instructions and reapply as needed. Depending on the product, you may need to reapply the spray after a certain period of time or after activities like swimming or sweating.

The Environmental Impact

Using mosquito spray to kill ticks can pose risks to the environment and other species. Mosquito sprays are not selectively toxic to only mosquitoes; they can also be highly toxic to native pollinators such as bees and butterflies, and may pose risks to pets and people. It is essential to consider alternative methods of controlling mosquitoes and ticks that have a lower impact on the environment and other species.

Preventive Measures

In addition to using mosquito sprays, consider implementing other tick control methods, such as keeping your lawn mowed, removing leaf litter, and creating a barrier between wooded areas and your lawn. Perform regular tick checks, shower within two hours of being outdoors, and avoid tick-infested areas.


While mosquito sprays can provide some protection against ticks, specialized tick sprays or treatments are generally more effective in preventing tick bites and tick-borne diseases. Always use mosquito control methods responsibly and consider the impact on the environment and other species.
