Pesticide Toxicity to Earthworms

UGA Entomologist Paul Guillebeau says: “As long as the pesticide is labeled for use on that site, the product does not have to have earthworms on the label. If she took this action well in advance of customers, the risks to people sitting on the ground would be reduced. If I were her, I would consider placing a cloth on the ground for people to sit. It could create the impression of a picnic, and the worms would be saved, and unnecessary pesticide application would be avoided.”
