Dang. I read this after blocking the hole with blu-tac. Seems odd, but that's all I have at the moment. I guess it's a temporary measure but it's holding for now. A few wasps are flying around outside it but they can't get in.
I plan on buying some foam / spray tomorrow and the good thing is that I know exactly where the hole is now; though it is tricky to get to it. Of course, I can't open the window just above it at the moment, which is a pain in this heat.
