The Texas Department of State Health Services has provided the following spray area map for the dates of
September 14th through the 20th. Weather permitting the spraying will start tonight and will be conducted over
different areas per night, from dusk till dawn.
The large aircraft, a modified C-130 military aircraft, can be seen flying low and heard from a distance. The
amount of insecticide used is about an ounce (one to two tablespoons) per acre. If you would prefer to stay
inside and close your windows and doors when spraying takes place, you can, but is not necessary.
The pilots will be conducting flights for aerial surveying during daytime hours. Do not be alarmed, these flights
are not releasing insecticide.
Organized outdoor activities such as football games will still see the low flying planes. The aircraft is
sophisticated enough to allow the insecticide spray to be regulated, and the pilots will stop the spraying as they
fly over these highly populated areas.
The insecticide that will be used is Naled. According to the CDC, when large areas need to be treated quickly
aerial spraying is the most effective and does not present a risk to people, pets or other animals. The
insecticide is dispersed by airplanes equipped with nozzles that create droplets just the right size to kill
mosquitoes. Once any remaining droplets settle to the ground, they quickly break down on surfaces, in water
and in sunlight.
Here are some ways that you can help eliminate mosquito problems:
Help eliminate any standing water (even small amounts) to prevent mosquitoes from laying their eggs.
If water cannot be eliminated, such as in ornamental water features, use larvicides (available at many
retailers) or other control measures to minimize opportunities for breeding. For example, you might be
able to add fish that eat larvae to a pond, or add a fountain or aerator to keep the water moving.
Use window and door screens to keep mosquitoes from entering your home, workplace, or children’s
Use EPA-registered insect repellents to prevent getting bitten. Products that are EPA-registered have
been confirmed to be safe and effective when you follow the directions.
Dress in light-colored clothing, long pants, and long sleeves.
