Fumigation is for one specific kind of problem: insects living inside something. Grain weevils deep in a pallet of sacks, moth larvae through a bulk store of feed, beetles inside a piece of timber furniture. A gas fumigant gets into every gap and kills every life stage. If your insects are walking across floors and walls, you don't need gas, and we'll point you to an ordinary treatment instead.
Start here: spray or fumigate?
Most of the calls we get about fumigation in Mossel Bay start with someone finding beetles or moths and assuming the whole building needs to be gassed. Often it doesn't. A quick way to think about it:
- Insects on surfaces, in cracks, around skirting boards: a residual spray or bait treatment. See insect control in Mossel Bay.
- Insects in one or two bags of flour or birdseed: throw the bags out and clean the cupboard. No gas needed.
- Insects through stacked stock, sacks, bulk produce or a whole storeroom: fumigation.
- Fresh exit holes and powder coming out of furniture or timber: often fumigation, depending on how far it has spread.
Why Mossel Bay sees more of this work
Mossel Bay isn't just a holiday town. The harbour, the refinery and the warehouses and depots around them mean a lot of goods are stored here, sometimes for months. Food, feed and packaged goods that sit for a long time give stored product insects a chance to breed through a whole stack before anyone notices. One infested consignment brought into a clean store can spread from pallet to pallet.
On the residential side, we're mostly called to furniture and household goods: an old wooden cabinet that has started dropping powder, or boxes of possessions that have been in storage and come back with insects in them.
The fumigation, step by step
- Site visit. We look at what's infested, measure the volume and check how well the space can be sealed. A tight storeroom can be fumigated as a whole. A store with gaps under the doors and open eaves is often better done by covering the stock with gas-proof sheeting.
- Planning with you. We agree a date, tell you how long the area will be out of use and what needs to be moved or switched off. For a business, this is where we work around deliveries and staff.
- Sealing. Doors, vents and gaps are sealed, or the stack is sheeted and weighted down.
- Application. A registered fumigant such as phosphine is applied by our trained operators, and warning signs go up.
- Exposure. The area stays sealed for the full time the product label requires. Cutting this short is how insects survive.
- Ventilation and clearance. We air the space out and test it. Nobody goes back in until we've cleared it.
The safety part, plainly
This is the one pest treatment where you can't stay in the building. While fumigant gas is in a space, that space must be empty of people and animals and kept closed. That includes staff, guard dogs, pets and anyone who might wander in to fetch something. It's also why fumigation is never a DIY job. A shop-bought insect fogger or smoke bomb is not a fumigant, and it won't reach insects inside sacks or wood.
A tip for Mossel Bay stores
Check goods when they arrive, not when the problem shows. Have someone look at the seams of sacks and the base of pallets on delivery, keep new stock apart from old for a few days if you can, and rotate stock so nothing sits at the back for a season. Sweep spilled product off the floor as you go, because a line of spilled grain along a wall feeds insects long after the stack above it is clean.
What most people get wrong
Many people think fumigation protects a building afterwards. It doesn't. The gas kills what's there and then airs out completely, which is exactly what makes it safe to return. If infested goods come back in next month, you're starting over. That's why we always pair a fumigation with advice on stock handling and, for businesses, regular inspections.
How much will it cost?
The price depends on the volume being fumigated, how easily it can be sealed, whether we're treating a whole room or sheeting individual stacks, and how much preparation the site needs. A piece of furniture is a small job. A full warehouse bay is a much bigger one, and businesses that store food or feed year-round often do better with an inspection contract that catches problems early. We'll give you a free quote after the site visit, including the exposure time and what you need to do on the day.

Questions we get asked
Can my staff keep working in the rest of the warehouse?
Sometimes, but only if the fumigated area can be properly sealed off from the rest of the building. We'll assess that on the site visit and tell you clearly which areas must be closed.
Will fumigation damage my stock or packaging?
Registered fumigants like phosphine are made for use on stored commodities and air out after treatment. We'll check what's being stored first, because some metals and electronics need to be moved or protected.
Does fumigation get rid of rats in a warehouse?
No, fumigation is aimed at insects in stored goods. Rats and mice are dealt with by a rodent programme of bait stations, traps and proofing, which we can run alongside a fumigation.
Can you fumigate just one piece of furniture?
Yes. Single items are usually sheeted and fumigated on their own, which is far less disruptive than treating a whole room.
When can we go back in?
Only once we've ventilated the area and tested it as clear. We give you an expected time when we book, and we'll confirm on the day.
