I didn't see many bugs, so I stored some dried food in plastic bags with the tops rolled over. I was in the UK for a couple of months in the summer and when came back I found weevils in the flour, rice etc. I threw it away and invested in some plastic containers with good seals. Haven't noticed any bugs in the kitchen since. To be honest, I've had more problems with ants in the UK than I've had with bugs here. Here, we have a bug man who comes and sprays around the house onece a month. There's an earlier thread on this subject somewhere in the archives, I think.

I think I'm right in saying that a/c units here generally don't also work as heaters. Certainly in our house they just cool.
