Mosquito Spraying Schedule

Vector Control crews will be spraying for mosquitos in the Annaville area between 6:30 p.m. and 11:00 p.m


The following routes will be sprayed.


Route 1 – Hwy 77 west to City limits

Route 2 – Hwy 77 east to Violet north of IH 37

Routh 3 – Hwy 77 east to Violet south of IH 37


Vector Control can only spray for mosquitoes when it is not raining and the wind speed is low. The pesticide dissipates very quickly when it comes in contact with the ground, especially if there is any dew.  Even then, the fogger only kills the mosquitoes that are actually airborne and come in direct contact with the pesticide at the time of the spraying, so it is not effective for any great period of time.

Since the fog only kills the airborne mosquitoes, spraying only occurs during evening hours, usually between 7:00 p.m. and Midnight. It is estimated the fog only kills one-third of the total mosquito population. 


Although Vector Control employees do their best to reduce the number of pest mosquitoes citywide, Corpus Christi Animal Care Services (CCACS) urges residents to take these personal precautions to avoid being bitten:

• Use an approved insect repellent every time you go outside and follow the instructions on the label. Approved repellents are those that contain DEET, picaridin or oil of lemon eucalyptus.

• Regularly drain standing water, including water that collects in empty cans, tires, bird feeders, buckets, clogged rain gutters and saucers under potted plants. Mosquitoes breed in stagnant water. Purchase mosquito donuts (dunks) at retail stores that kill mosquito larvae in standing water. 
• Wear long sleeves and pants at dawn and dusk when mosquitoes are most active.
• Use air conditioning or make sure there are screens on all doors and windows to keep mosquitoes from entering the home.
• Keep grass cut and yards maintained. Treat the yard for mosquitoes, fleas, and pests.
