Hi All
When we first moved in we had our barn sprayed with insecticide. It has been good for 6 years. But we are seeing wood dust coming down from the roof beams and roof boards.
We could get it re-sprayed buy I have been looking at insect smoke bombs. Has anyone any experience of these?
Regards
Nick
Smoke bombs have no residuel effect, so useless against insects burrowed in wood.
Spraying is the best option; I’m not a fan of injecting, it’s unnescessay and expensive in my opinion.
On the DIY tin it give a 10 or 20 year guarantee protection, with a big asterisk: Ideal temperature, air flow, humidity etc.
Respraying, even after 6 years is not unreasonable if all the criterias as expressed on the tin are not met.
