As temperatures rise, the City of Arlington is calling on residents to help eliminate mosquito breeding grounds before the peak of West Nile Virus season. Mosquitoes can develop in stagnant water in as little as three to four days, making weekly property inspections vital.

The “Tip and Toss” Checklist: To protect your family and neighbors, residents are urged to follow these steps:


Remove Clutter: Dispose of old tires, tin cans, buckets, and unused toys that hold rainwater.
Refresh Water Sources: Change pet dishes and bird baths every 48 to 72 hours.
Maintain Your Home: Keep rain gutters clear of debris and drill drainage holes in tire swings or trash cans.
Cover Up: Ensure rain barrels are tightly screened to prevent egg-laying.
Landscape Smart: Fill in low spots in the yard where water pools after a storm.
Pro Tip: If it can hold a tablespoon of water, it can breed hundreds of mosquitoes.

“Our best defense against West Nile Virus starts in our own backyards,” Health Services Manager Aimee Rockhill said. “A few minutes of yard work each week can significantly reduce the mosquito population in our neighborhoods.”
