I live in 35 year old little, predominantly teak, house in the countryside.

I've noticed a few flying insects (some look like blue and yellow bumblebees) burrowing into pieces of timber around the house. Also some of the wood seems to have at one point housed other insects as there is a lot of "scarring" on the wood.

I'm pretty sure we aren't infested with ants or termites but is there a reppellent paint or oil or varnish I can brush into the wood to rid it of these insects?

I'm not really too ofay with these types of products so the actual names of any products you could recommend would be most appreciated.

Thanks

I have seen cuprinol for sale in my local hardware store. You might want to look into it. It is AKA copper-green

Thank you rucus7
