Spiders.
Here's a little trick I learned for energy efficiency, but it works for pest control as well.
Look for spider webs. Spiders build their webs where food comes in. If you see spider webs, rest assured that there are gaps / leaks very close by. Find those holes, seal them, and remove the web. If the spider does not rebuild the web, job well done. If the web keeps reappearing you didn't completely seal the hole.
Clear as mud?
