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.
After re-entry, ventilate, wipe food-contact surfaces that were treated or exposed, and do not mop treated skirting lines for the period the technician specifies, since washing removes the residual barrier you paid for. If anyone develops headache, nausea or breathing irritation after re-entry, leave, ventilate and call the company and a doctor rather than waiting it out.
