This last few months Ive been finding these 2mm, black, oval, hard, round backed beetle type insects alive or dead on the window sills around the house. Every day there will be about half a dozen on most of them and Ive no idea what they are or where they're coming from It suddenly struck me this morning they might be the adults of wood worm, but Ive no idea what wood worm look like and couldnt find anything on google Our house is a 1930s one, we've owned it for 2.5 yrs. Can anyone help? If they ARE wood worm, how do we find where the infestation is and what's the likely cost of clearing it up?
thanks
