Sentry Natural Defense household products are safe enough to use as often as needed. However, Sergeant's recommends waiting 24 hours after the first application to ensure that the fleas and ticks are gone.
Walking on the carpets is not recommended while Sentry®HOME Flea and Tick Carpet Powder is still down, and you will want to keep all pets and children off of the carpets until you have vacuumed up the powder. As long as you are able to restrict your pet to an area of the home that has not been treated with the powder, the animal can be in the home while the carpets are being treated. Once the powder has been vacuumed from the carpets, you, your children, and your pets are safe to return to your normal routine.
Sentry® HOME Household Flea & Tick Spray will take approximately 2 hours to dry. You are not required to leave the house during this time frame, but it is recommended that any people, children and pets stay out of any treated rooms while the spray is drying. Please note these estimated times may be longer in areas with high humidity.
