Well for me I keep my cooler in a room that never gets sun. It stays pretty cool. About 65. That helps a lot. But other than that unless your gonna cool the whole house there isn't much you can do. from what I have heard though it requires humidity and temp to be above 70 for beetles. So as long as the humidity is down you should be fine.I've removed one of the packs sense the photo. RH is down to 68.Careful brother. When temp and RH go above 70 you can easily get beetles.Its not fancy but it does its job.
getting the temp down is the biggest problem i have had.
any advice?
