What to do before a pest treatment, and what happens after

A general treatment doesn't need the house emptied. It needs about ten minutes of the right kind of tidying, and a clear idea of what not to clean afterwards.

By the Avalanche Pest Control team · · 6 min read

Most first-time customers ask the same few questions before a general pest treatment, mainly whether the house needs to be empty, whether it's safe for the kids and the dog, what happens to the fish tank, and what's actually safe to clean once the technician's gone. None of it is complicated, but getting it wrong on either end, over-preparing or cleaning away the wrong thing afterwards, either wastes your morning or wastes the treatment.

Before we arrive

A general pest treatment goes along skirtings, wet areas, eaves, weep holes, window frames and the entry points around the home, so the main job is clearing a path to those spots rather than emptying the house.

Move anything stacked against a skirting board or an external wall (boxes, the vacuum, the kids' bikes) so the perimeter is reachable. Pull furniture a hand's width off the walls in rooms that get treated internally. If there's a subfloor or roof access, make sure it isn't blocked or painted shut. Outside, clear anything pushed up against the foundation line: firewood, pot plants, the bin.

Food and dishes get put away or covered, benches wiped down, and pet bowls and bedding moved out of the rooms being treated for the morning. None of this is because the product is dangerous sitting in the open; it's the same commonsense you'd use before any tradesperson works through a kitchen.

Kids, pets and the "do we need to leave" question

For a standard general treatment, no. It's low-disruption: you might step out of a room while a particular spot is being done, and there are usually a couple of hours where a treated area needs to dry before it's back to normal use. Professional pest products are applied to where the target pest actually lives and travels, skirtings, cracks, weep holes, not sprayed across the surfaces your family touches, which is the main difference between a licensed treatment and a can of something from the supermarket.

Once an area's dry, it's back to normal. If you'd rather keep young kids and pets off freshly treated floors until then, that's sensible and easy to plan around; just say so when you book and the order of the job can work around nap times or the dog's afternoon inside. The same "safe once dry" answer applies across our other targeted jobs, spider control included.

Products vary, and so do label instructions for the specific chemical being used that day. The label is the actual authority here, not habit or what a previous company did at your place. Every registered domestic pest-control product carries mandatory caution and safety-direction statements, and one that applies across the board: it must not be sprayed directly on people, pets, exposed food or food-preparation surfaces. That's an APVMA labelling requirement, not a house rule, and any technician applying a registered product needs a current pest management technician licence from the NSW EPA and is bound by it regardless of who they work for.

Fish tanks and birdcages

These are the two things people forget, and they're the two things you actually need to act on.

An aquarium's water surface and the airstone bubbling through it pull room air straight into the tank, and household insecticides are broadly toxic to fish even at concentrations that don't bother a mammal. The same label rules that ban spraying into drains, streams and ponds exist because these products aren't meant to reach open water, and an aquarium is open water sitting in the room being treated. Turn off the air pump and cover the tank for the treatment and for a while afterwards, and if you can, move it to a room that isn't being sprayed that day. Ask your technician when you book; they'll tell you what the specific product being used that day needs.

Birds are similarly sensitive to airborne particles, more so than most household pets. If there's a cage in the house, the same logic applies: cover it, or better, move the bird to a room that isn't part of the job, and keep it there until the treated areas have properly dried and aired.

What happens during the visit

Internally, that's skirtings, wet areas and cracks and crevices where pests travel. Externally, the eaves, weep holes, window frames, garden bed edges and the perimeter of the slab or footing. The result you're paying for is a treated barrier that keeps new pests from settling in, not just a knockdown of what's visible on the day, which is also why a good technician will ask what you've actually been seeing rather than just walking a standard route.

If something specific has been reported, spiders in one particular eave, ants at one entry point, say so before the job starts. It changes where the time goes.

What not to do afterwards

This is where people undo their own treatment without meaning to. Don't mop or wipe down the treated skirtings, cracks and entry points straight away. The residual film left on those surfaces is most of what makes a general treatment keep working for months rather than days, and washing it off early is close to not having done it at all. Normal cleaning everywhere else in the house is fine from the moment surfaces are dry. If you're not sure which areas were treated, ask before you start cleaning; it's a two-minute conversation and it's cheaper than a call-back.

Airflow is the other half of it. Open the windows for the afternoon once the technician's gone, particularly in rooms that back onto the treated perimeter, so the smell clears and surfaces dry at a normal rate rather than staying damp in a closed-up room.

If something still turns up

A few pests wandering through in the first day or two is normal. Anything already in the treated zone when the product goes down has to cross it to get out, which is often when you see the most activity, not the least. What's worth a call is activity continuing unchanged after a week, or turning up somewhere the treatment didn't reach at all, which usually means there's an access point that needs a second look rather than a second dose of the same thing.

If you're weighing up quotes before you book, the questions worth asking, what's included, what's used, and what you need to plan for on the day, are the same ones covered in why one quote is $120 and the next is $400. For anything specific to your place, give us a ring before you book.
