Thanks for the info, but I don't think I'm going to stop using them. They say everything causes cancer these days, and since no types of cancer run in my family, I'll take my chances. Plus I'm never really in my grow room for longer than 30 minutes at a time. I never let any kids in my grow room and if my girlfriend gets pregnant (knock on wood ) I'll take it down. For now, I'll take my chances in order to have no bugs eating my plants in my bug infested basement.

EDIT:
When male and female rats were given a diet containing 100 ppm (5 mg/kg/day) dichlorvos just before mating, and with this dosage continued through pregnancy and lactation for females, there were no effects on reproduction or on the survival or growth of the offspring, even though severe cholinesterase inhibition occurred in the mothers and significant inhibition occurred in the offspring.
Doesn't that mean its not really a reproductive risk? And they were having it fed to them?
