Woodworm aerosol cans

These seem to have been discontinued. Anyone know why?

The shops tell me (of course) that the ordinary tins are just as good.

Anyone have an opinion?

Dupe

Anyone at all? :-)

Maybe because there isn't much sense in filling the air you breath with insect killing chemicals?

There is also not a whole lot of point spraying the woodworm holes (except to get deeper chemical penetration) because the hole means the woodworm has flown the nest.

If the entrance to the hole is recently mounded with sawdust does that also mean that nobody is in?

If the wood has been polished does the product still soak in or do you have to prepare the surface first?

My understanding is that woodworm treatment is primarily to prevent a new infestation. If you soak the timber in woodworm treatment then the beetles die as they emerge. I don't think they are all killed while still deep in the wood. In fact I've treated timbers and come back to find piles of dead beetles. Any fresh infestation is prevented as the wood is now toxic to the larva as they emerge from the egg and start to burrow into the wood. The surface of the wood being treated with chemicals.

The instructions on the tin for most woodworm killers is to strip the surface first. If its just polish and not varnish then any of the stinky products will probably strip or at least soften the varnish a they are applied.

Often its only one part of a piece of furniture thats attacked (at least initially) as some wood is more attractive to woodworm than others. Old plywood drawer bottoms always seem to be a favourite.

If you want to treat the holes which must do something then Rentokill do a can with a spout that you can poke into the holes and squeeze the can, although I think its a plastic bottle now rather than the metal cans they used to use.
