If you've found fresh, round holes in a wooden table, a little heap of fine powder underneath it, or insects right through a sealed store of food, fumigation is probably the answer. A registered fumigant gas penetrates the wood or the stock and kills every life stage, including the larvae you can't see. If what you've got is on surfaces, though, a spray will do, and we'll tell you before you book anything bigger.
Why Sedgefield calls for fumigation
Sedgefield is a relaxed lakeside and coastal town between Wilderness and Knysna, close to Swartvlei and the lagoon, with homes that often sit near wetlands and dunes. The air is often humid, and many houses are holiday homes that are closed up for part of the year. That combination suits wood-boring beetles in furniture and timber, and it lets pantry and storeroom insects breed undisturbed while nobody is home.
We also see a fair number of thatched houses here. Thatch matters for fumigation, because a roof like that is much harder to seal than a tiled roof over a closed ceiling. In practice, that usually means we fumigate individual pieces under gas-proof sheeting, or a room that can be properly sealed, rather than the whole house.
Is it active, or is it old damage?
This is the question that saves the most money, and it's the one most people skip. Old borer holes stay in the wood forever, so a piece of furniture covered in holes isn't necessarily infested now. The signs of an active problem are:
- Fresh, light-coloured powder (frass) on the floor or on the furniture, coming back after you've cleaned it away
- Holes with clean, sharp edges and pale wood inside, rather than dark, weathered ones
- New holes appearing that you didn't see last season
- Small beetles near windows or on the floor in warmer months
A simple test: vacuum the powder away, then check again in a couple of weeks. If it's back, something is still feeding inside.
How we fumigate in Sedgefield
The assessment
We look at what's infested, how much of it there is, and whether we can seal the space well enough. Single pieces of furniture, a box of antiques or a cupboard of stored goods can be sheeted on their own. A sealable room or outbuilding can be treated as a whole.
Preparing the site
We'll tell you what needs moving, what to take out of the room and what we'll seal. Food that isn't being treated, pets, plants and certain metal items or electronics may need to go elsewhere.
The fumigation
Our trained operators apply a registered fumigant, such as phosphine, and seal the space or sheeting. Warning notices go up. The area stays sealed for the exposure time on the label, because cutting it short lets some insects survive.
Clearing
We ventilate the space and test it before anyone goes back in.
Please note: unlike a normal spray treatment, fumigation requires the sealed area to be vacated. People and animals must stay out until we've cleared it. That's not negotiable, and it's why fumigation is only ever done by registered operators.
Stopping it coming back
The fumigant kills what's there, airs out and leaves no protection behind, so prevention matters. In a Sedgefield home, the local tip is to manage damp: open the house up when you arrive, run a dehumidifier or keep air moving in closed-up rooms, and keep wooden furniture away from walls that face the lake or wetland side and tend to stay damp. Check secondhand furniture and boxes from storage before they come indoors. For pantry insects, keep dry food in sealed containers, especially in a holiday house.
How much will it cost?
Fumigation is priced on the volume treated, how easily it can be sealed and how much preparation is involved. Sheeting a single cabinet is a small job. A sealable outbuilding full of stored goods, or several rooms of furniture, is a larger one. We'll visit, confirm whether the infestation is active, and give you a free quote that includes how long the area will be out of use. If the damage is old and nothing is feeding, you won't need fumigation at all, and we'll tell you that.

Questions we get asked
Can you fumigate a whole thatched house?
It's rarely practical, because thatch is very hard to seal properly. We usually fumigate affected furniture under sheeting, or a room that can be sealed, which deals with the infestation without trying to gas the whole house.
How long will my furniture be out of use?
It stays sealed for the exposure time on the fumigant label, plus ventilation and clearance. We'll give you the expected timing when we book.
Will fumigation damage antique furniture?
Fumigants don't stain or wet the wood the way a liquid treatment can. We'll check finishes, metal fittings and anything delicate before we start.
Can I stay in the house while one room is fumigated?
Only if that room can be sealed off completely and we're satisfied it's safe. If not, the house must be vacated until we've cleared it. We'll make that call on site.
Does fumigation work on termites in the garden?
No. Fumigation is for insects inside wood, stored goods or sealed spaces. Insects in the garden or soil need a different treatment.
