City of Rockville Offers Tips to Reduce Mosquito Breeding on Your Property

The City of Rockville provided the following tips to prevent mosquito breeding on your property during the warmer months.

Mosquito species that have the potential to spread viruses prefer to breed in small amounts of standing water near where people live and work. They typically do not breed in natural areas like streams and ponds.

• Empty out water from children’s toys and plastic containers. If possible, bring indoors. Cover large toys and sandboxes with tightly fitting tarps, or drain weekly.
• Remove trash from the yard. As little as a bottle cap full of water is enough for mosquitoes to breed.
• Clean out roof gutters and downspout screens. If possible, replace corrugated downspouts with smooth PVC.
• Store recycling bins out of the rain. Dump out any water at least weekly. Even though bins have drain holes, small amounts of water may still collect.
• Add an aerator or fountain to birdbaths or ornamental ponds. Mosquitoes do not breed in moving water.
• Tighten tarps and pool covers to minimize folds. If water still collects, shake out the tarp at least weekly.
• Fix outdoor leaks and dripping faucets. Get rid of puddles from window air conditioners.
• Dump and scrub saucers under potted plants, and flush birdbaths at least once a week.

Where to Check:

• Front yard.
• Backyard.
• Along edge of the property.
• Balconies (apartments too!).
• Deck.
• Roof and gutters (follow safety precautions).

Note: Mosquito species of concern typically do not fly more than 150 yards from where they breed.
