Before and after pest control: preparing the home, food, kids and pets

Half of what decides whether a pest treatment works happens before the technician rings the bell, and another quarter happens in the two days after they leave. The chemicals are the same in every house; the preparation is not. Here is the full checklist, and the reasons behind each item so you can judge what applies to your home.

Before the visit

Food and water. Everything edible goes into hard, sealed containers or the fridge — including the fruit bowl, the bread, the open biscuit packet, pet food, and the water filter's dispensing tap area, which should be covered with a cloth or plastic. The rice and dal sacks either get sealed or moved out of the kitchen for the day.

Kitchen access. Clear the worktops completely and wipe them down. Empty the under-sink cabinet and the cabinet next to the hob — those are the two most important treatment points for cockroaches. Pull the fridge and washing machine out a hand's width if you can; if not, the technician will.

The rest of the house. Toys off the floor, and anything a baby might mouth put away. Beds stripped if the visit involves bed bugs. Fish tank covered and its air pump switched off for the duration — aquarium fish are extremely sensitive to sprays. Cover the bird cage and move it out, ideally to a neighbour's for the day.

People and pets. Plan for everyone — children, pets, and anyone elderly or asthmatic — to be out during the treatment and for the re-entry period the technician specifies. A dog shut in one room while the rest of the house is sprayed is not out; the mist travels.

Tell the technician everything. Who lives in the house (a crawling baby changes gel placements), any allergies or breathing problems, pets and where they roam, and what you have already sprayed yourself — DIY spraying in the previous days changes where the pests will be hiding.

During

Stay out of the rooms being treated. Windows are usually closed during a spray or fog so the mist works, then opened for ventilation after — the technician sequences this. Do not run ceiling fans during spraying; they throw the mist off target.

After: the first day

• Ventilate when the technician says to: windows open, fans on, for at least an hour before the family returns.
• Surfaces you eat off — dining table, worktops, the high chair tray — get a wipe with soap and water even if they were covered.
• Wash any utensils or food items that were left exposed by mistake. When in doubt, wash it.
• Children and pets come back in only after floors and surfaces are dry, and the very young, pregnant and asthmatic last of all.
• Expect to see pests in the open, moving slowly, for the first days. That is the treatment working, not failing.

After: the next two weeks

• Do not mop the edges. The residual band along skirtings, corners and behind appliances is the long-acting part of the treatment. Mop the middle of the room after 48 hours if needed; leave the wall margins dry for two weeks.
• Do not wipe gel dots. Cockroach gel in hinges and corners must stay until it is eaten. Clean around it.
• Keep the kitchen tight. Sealed food, dry sink at night, bin out every evening. A treatment plus a generous kitchen is a fed colony next door waiting to move in.
• Note what you see. If live cockroaches are still common after three weeks of a gel treatment, that is warranty territory — both the cockroach job and the full home treatment carry a 30-day warranty. Report it rather than reaching for a spray can, which undoes the bait work.

Nellore-specific notes

In the humid months, dry surfaces take longer to actually dry — allow extra ventilation time before bringing children back rather than going by the clock alone. If a power cut stops the fans, open windows on both sides for a cross-breeze. And during the monsoon, plan the visit for a dry morning where possible: open windows for ventilation and rain do not mix, and outdoor perimeter spraying washes away if heavy rain follows within hours.

What no preparation can replace

If the sink trap leaks, the drain has no cover, or the door gaps are unsealed, say so — the technician can point out fixes, but the plumbing repair is its own job. Treatment kills what lives in your house today; the preparation and the follow-through decide how long it stays gone.
