It is usually safe for pets to go outdoors immediately after a pest treatment. There may still be residual chemicals that can be toxic if they are ingested. It is best to keep your pets indoors until the area has aired out. To speed up the process, it is a good idea to open doors and windows if possible. It is best to wait at most 24 hours after treatment before allowing pets into treated areas. This will allow the chemicals to dissipate and break down, which makes them less likely to cause damage if they are ingested. Every situation is unique, so you should consult your pest control professional for specific instructions. You should always be cautious if you are concerned about your pet's safety. Keep them inside until they can go outside. These simple guidelines will help you ensure your pet is safe and healthy following a pest control treatment.
