HOUSTON, Nov 09, 2004 (United Press International via COMTEX) -- Mosquito fighters in south Texas are worried indiscriminate use of insecticides is creating spray resistant bugs.

Harris County's chief mosquito fighter has recommended rotating the spraying of a handful of still-effective pesticides next year to maximize their usefulness, the Houston Chronicle reported Tuesday.

Still, Ray Parsons thinks it will only be five to 10 years before the area sees resistance to every pesticide.

Part of Parson's concern is private companies bid low to get spraying contracts and then dilute their insecticide to ensure a profit. He is not the only one concerned about such practices.

"I have no question that this is happening," says Raleigh Jenkins, owner of ABC Pest, Pool & Lawn Services, one of the largest pesticide companies in Houston.

He says his trucks spray at the rate recommended by label pesticide labels, but he knows some of his competitors are not. Some private bids to municipalities and communities are lower than the actual cost of the pesticides, Jenkins says. To make money on these cheap bids, the product has to be diluted.
