I have both a lang and a TBH with a package in each going on a month. Evidently they came with beetles because I started noticing them immediately. It doesn't seem that the TBH is having as bad a problem with them as the lang, but I am wondering what kind of control methods to use. None of the things I am doing in the lang ( tray of cooking oil under the SBB or beetle eater) seem like they would be practical in the TBH. Any suggestions?
