After any significant rainfall, the public must remember their role in the effective control of mosquitoes. Besides removing any standing water, yard maintenance is key as tall grass is a popular breeding area for many species of mosquitoes.

Vector Control is also asking for the public to remember the 5 D’s of Defense:

DEET – Use insect repellent containing DEET.
DRESS – Dress in long sleeves and pants when you’re outside.
DAWN, DAYTIME, and DUSK – Dawn, Daytime, and Dusk are the times of day when mosquitoes are most active. Avoid being outside during these times of day to prevent bites.
DRAIN – Regularly drain standing water, including water collected in empty cans, tires, buckets, clogged rain gutters, and saucers under potted plants. Mosquitoes breed in stagnant water.
DOCTOR – Consult a physician if you feel sick after being bitten.

Don’t forget your pets! Dogs need limited time outdoors since they are susceptible to heartworms caused by mosquitoes. Please only use veterinarian-approved insect repellents on your furry friends.
