What a home visit actually involves
The technician inspects before anything is applied: the kitchen and its voids, under and behind appliances, the bathrooms and their service ducts, wardrobes on external walls, the balcony, and wherever you have seen activity. The point is to find where the population lives rather than where you noticed it, because those are usually different rooms.
What is applied then follows from what was found. Gel bait into voids for cockroaches, a targeted residual on routes and entry points, treatment around external doors and drains where the pressure is coming from outside. Not a blanket spray through the house, which puts product where nothing lives and none where it does.
