For educational materials on measures to minimize the mosquito population and information concerning community outreach, call MDA at 410-841-5870 or the Department of Health at 410-222-7192.
MDA monitors mosquito-breeding sites to assess the need for larvicide application and mosquito-spraying services. Mosquito spraying is undertaken to protect public health and for nuisance abatement in participating residential communities. For more information about mosquito spraying, click here. See Anne Arundel County Mosquito Control Adulticide Spray List. For more information about larvicide application, click here.
The use of insecticides to control the adult mosquito population is undertaken as a secondary control measure, since insecticides are short-lived and provide only a temporary means to reduce the adult mosquito population in a geographic area.
What measures can a homeowner take to reduce the number of mosquitoes in a community?
The most important thing a homeowner or community can do to reduce the number of mosquitoes in a given area is to eliminate potential breeding sites on a property. Outdoor containers that are capable of holding rainwater are considered breeding sites for mosquitoes and mosquito larvae. Homeowners are encouraged to inspect their property and eliminate any outdoor containers capable of holding water during the spring, summer and fall. Outdoor containers that are capable of holding rainwater that should be eliminated from a property include:
- flower or garden pots*
- gallon containers
- plastic bags
- kiddy pools
- trash can lids
- trash cans (w/out lids)
- non-circulated ponds and swimming pools
- clogged or poorly drained gutters
- rain barrels
- corrugated piping
*Water in birdbaths, and flower and garden pots should be replaced every 3 days to eliminate mosquito larvae from maturing into adult mosquitoes.
Many homeowners have installed ornamental ponds in their yards. It is important to keep these ponds populated with fish to eat the mosquito larvae. These ponds are breeding grounds for mosquitoes, and the fish will control the population. If you cannot keep fish in the pond, placing larvicide dunks or circulating the pond is necessary.
How do I file a complaint about the mosquito population in my community?
MDA responds to service requests from County residents or communities participating in the mosquito-spraying program. MDA will assess a property for outdoor container complaints to determine if mosquitoes can breed or develop on the property. MDA will also respond to service requests from participating communities where mosquito populations appear to be in excess of the action threshold.
