A: In general, it is usually safe to have a pest control company spray when children are living in the house. However, keep in mind that different types of compounds are used, depending on the pest that you're trying to terminate. Always contact a representative from the company in advance of the treatment to see if it is safe and if any precautions are necessary, like waiting for the treatment to dry or not spraying in play areas. Make sure that the company is providing treatments only when they are necessary, and find out if they provide any natural treatments or alternative solutions to the pest problem. It would also be helpful to confirm things with the service provider when they arrive at your house.
