Children, pets and re-entry windows
The most common safety question is the simplest: when can we go back in. The honest answer depends on the treatment. Gel baits and traps need no evacuation at all, which is one reason they dominate kitchen work in family homes. Residual sprays typically require the treated rooms to be vacated during application and then ventilated, with re-entry after roughly two to four hours once surfaces are dry; the technician should state the exact window for the product used. Fogging or misting indoors extends that, and anyone pregnant, asthmatic or medically vulnerable should stay out longer and say so when booking.
Preparation is your half of the safety contract. Before the visit, store food, utensils, pet bowls and children's toys away from treatment zones or cover them; empty lower kitchen cupboards if the technician asks; and move fish tanks out or seal and switch off their air pumps, because aquariums are acutely sensitive to airborne pyrethroids. Cats deserve special mention: they are far more sensitive to permethrin-class products than dogs, so tell the company you have a cat and keep it out of treated rooms until everything is fully dry.
