That leaves much of Harris County and the city of Houston under the protection of the Harris County Mosquito Control District.
Yet the district has only 10 trucks, which spray pesticides such as malathion at night.
Harris County has about 19,200 miles of roads. If a truck works all night, it can cover about 40 miles. That means the average house has about a one-in-50 chance of getting sprayed tonight.
A lack of spraying may be just as well, argue pesticide-control advocates, who say the county should warn people before they spray a neighborhood with chemicals such as malathion.
"At the very least, people should close their windows, if possible, bring in their pets and don't let their kids into the yard after spraying has occurred," said Stephen King, a toxicologist with Texans for Alternatives to Pesticides.
The Environmental Protection Agency has determined, however, that exposures to even repeated air and ground applications of malathion range from 100 to 10,000 times below an amount that might pose a health concern.

I once bought an attachment muffler for my lawnmower with a tube you pour the special insecticide into the muffler and it vaporizes.
They are legitimate. The best control method is to pour a little oil in the stagnant water They use special oils which disperse to a very fine skin.
Here is a quote from a Florida web site.
In the past the Florida Keys Mosquito Control District used thermal fogging to apply adulticides. The pesticide was diluted with diesel oil and passed through the engine of the plane or the blower in the back of the truck. This produced a thick cloud of smoke that was easily seen. It also produced a certain level of pollution due to the burning of the oil. Now the district uses ultralow volume or ULV applications. A very small amount of pesticide is applied in droplets about the diameter of a human hair. ULV allows mosquito control to use less pesticide to achieve the same results, while eliminating pollution due to use of the diesel oil carrier.

I just read a news article from the local news channel down here in Alabama that says Mosquito Spraying has begun here. I was wondering, do they have trucks anywhere else like in the north that go around pouring mass amounts of insecticide into the air like they do here? And this stuff can't be healthy. Really though....it doesn't really decrease the amount of mosquitoes in my opinion. Of course, they spray all the time so I don't really know what it would be like without it. Do you think the pros of mosquito spraying outweigh the cons?
