Barrier spray mosquito treatments work right away – and keep working for weeks.


When you contract Mosquito Joe of Baltimore for mosquito control, a trained technician will treat your yard with an effective barrier spray that eliminates biters for 21 days. Using a backpack sprayer designed for precise application, your technician targets shrubs and plants with a barrier spray that kills mosquitoes on contact and bonds to foliage, where it acts as a mosquito repellent for weeks to come. Within 30 minutes of spraying, your yard is ready for family and pets to come out and enjoy the outdoors.

Did you know that a bottle cap full of water is enough for a mosquito to lay up to 300 eggs at a time? Your yard is full of potential mosquito breeding grounds. We inspect your property for active larvae populations, and help you identify potential mosquito breeding grounds in your yard and recommend ways to eliminate standing water. These notes will be left on the post-service door hanger at the end of the treatment. Every three weeks, our team returns to treat your yard.

Pyrethrins are insecticides that are derived from a naturally occurring compound called pyrethrum found in the chrysanthemum flower. Pyrethroids are used in numerous commercial products that consumers use to control insects, such as household pets insecticides, pet shampoos and sprays, and even lice shampoos applied directly to the scalp. The standard barrier spray treatment is effective on other pests as well, such as fleas, ticks and even flies.
