Even though sewage treatment plants are not designed to remove tiny amounts of pesticides, they do an excellent job of dealing with the most widely used family of home and garden insecticides, scientists reported here today. Their study on pyrethroid insecticides — used in more than 3,500 products — was part of the 246th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society.

Bed bugs, largely absent in the U.S. since the 1950s, have returned with a hungry vengeance in the last decade in all 50 states. These insects have developed resistance to pyrethroids, one of the very few classes of insecticide used for their control. A research team at Virginia Tech has discovered some of the genetic mechanisms for the bed bug's resistance to two of the most popular pyrethroids -- deltamethrin and beta-cyfluthrin. The discoveries will accelerate efforts to understand the...

Effects on IQ appear to be similar to lead exposure When the EPA phased out the widespread residential use of chlorpyrifos and other organophosphorus (OP) insecticides in 2000-2001 because of risks to child neurodevelopment, these compounds were largely replaced with pyrethroid insecticides. But the safety of these replacement insecticides remained unclear, as they had never been evaluated for long-term neurotoxic effects after low-level exposure. In the first study to examine the effects of...

Pyrethroid insecticides, commonly used in California to kill ants and other insect pests around the home, have been found in street runoff and in the outflow from...
