How long until my backyard is safe for dogs after residual bug killer?
Hello. Most sprays are safe for pets once the spray has dried, or has been watered into the lawn. I would be sure there are no food or water bowls that might have been sprayed. Either toss them or wash in hot soapy water. The same goes for any chew toys out there. But generally, once a spray has dried, or the area has been watered down & allowed to dry, pets can roam freely, again. The only concerns would be if your dog eats a lot of grass, or finds something to chew on that was left out & sprayed, so keep an eye out for this. It might also be a good idea just to wipe paws off with a damp paper towel once they are ready to come back indoors. Thanks for contacting Petco Pet Education Center, formerly Petcoach.
