For lawn applications we can call before we come to treat the lawn so that you can keep kids and pets indoors until the products have dried on the lawn or have been watered in. For structures, pesticides are applied well away from children and pets in places such as cracks and crevices, behind heavy appliances, behind switch plates, underneath siding, etc. where insects hide and breed. Our company policy is to keep people out of the treated are until it dries or for up to 2 hours. That is why we ask people to keep kids and pets inside the house while we perform our applications. It usually takes an hour or less for the spray to dry.
