Warm spring weather can cause mosquito larvae to become active, producing adult mosquitoes. The Maryland Department of Agriculture (MDA) will begin applying mosquito larvicide control products to standing water in known breeding areas to prevent the development of larvae into biting adult mosquitoes.

West Nile and Zika virus are both transmitted by mosquitoes. To help control the mosquito population in your community, remember to tip anything that holds water on a weekly basis (birdbaths, old tires, plastic children’s toys, tarps, pet dishes etc.)

For permanent areas of standing water (ponds, rain barrels, etc.), mosquito “torpedoes” slowly and continuously release an insect growth regulator into the water that prevents larval mosquito development into adults for up to 2 months. The City offers mosquito torpedoes for residents – visit the Department of Public Works for more information.

The adult spray portion of MDAs program is scheduled to start in late May/early June and run through September to trap and control mosquito populations. More information can be found on our website www.collegeparkmd.gov/mosquito.

Residents can request exclusion from the adult spray program by completing an exemption form annually and return it to:

Program Supervisor, Mosquito Control Section
50 Harry S. Truman Parkway
Annapolis, MD 21401
