I have hundreds of crickets in my basement every fall. I see them crawling up my foundation so when I looked underneath the siding I see this. There is what looks like ripped plastic paper but then just a large gap into my basement around the entire house.
Is there supposed to be a direct entrance into my basement under the siding? (Maybe for moisture reasons or something?) If not what should I fill this with. Would like to do it once but do it right.
If the gap is supposed to be there could I install a mesh like this to help with the problem?
