City of Corpus Christi Warns Residents to Guard Against Mosquitoes

The City of Corpus Christi is encouraging residents to put up their guard before the mosquito population comes out with a vengeance.

With the warm and humid conditions combined with plenty of unchecked water sources, the city could become a hotbed for mosquito population explosion. The City is asking residents to remove any standing water, including water that may be left over in rain gutters, old tires, buckets, bird baths or unused pools.

Also, make sure to replace outdoor lights with yellow bug lights, which tend to attract fewer mosquitoes than ordinary lights; and remember to wear long sleeves and pants at dawn and dusk when mosquitoes are most active.

From the Corpus Christi Police Department:

The Corpus Christi Vector Control section consists of threefull-timee employees, who are responsible for a number of other key tasks besides mosquito spraying. From 8 a.m.-5 p.m., they are responsible for pesticide treatment of all city buildings, collecting and processing mosquitoes from the various traps throughout the city, and swarming bee eradication. Employees check approximately 27 mosquito traps each morning, and then observe the trapped mosquitoes under a microscope to determine the exact species. Large numbers of mosquitoes in certain areas suggest that the area residents should take extra precautions when outdoors and the area may need to be fogged. The areas to be sprayed are determined by the number of mosquitoes caught in traps, not by the number of complaints coming into the city call center.

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 p.m.-midnight. It is estimated that the fog only kills one third of the total mosquito population. Currently no specific areas have been identified for special fogging.

Although Vector Control employees do their best to reduce the number of pest mosquitoes citywide, ACS 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.
