Default Re: Another woodworm question!

The furniture beetle lays its egg in an attractive, secure life supporting crevice late spring/summer - they very rarely lay an egg in a flight hole, though nothing is impossible.

It is impossible to say where or when they will attack or emerge. The only certainty you have of an attack is from the fresh, fine gritty dust as they emerge from a flght hole April to June - how they know that date or how close they are to the surface is beyond me!); that is the only time that a woodworm killer has any real change of doing its job and when freezing/fumigation works best.

Pouring gallons of stuff down disused flight holes only adds to Mr Rentokil's profits! But regularly treating joints and dusty crevices is beneficial as these support the larvae's early life. You have to remember that only steeping timber in a bath of preservative over a week or so actually allows preservative to soaks into the cells by osmosis and leave sufficient insecticide to do its job as the vehicle evaporates. Brushing woodworm killer onto wood leaves only a useless trace deposit as the vehicle will have evaported long before it penetrates meaningfully into the cell wall. Poorly treated timber only gives the larva a headache and indigestion.

Treated 'woodwormed wood' is more likely not showing further signs of attack because the attack is long since gone or the environment is not attractive to the furniture beetle, which usually lives on damp wood or decaying wood.

Nature will always win over man - vigilance over attacks is the key!
