As for SHB on the inner cover; I take a cd case, heat an ice pick and put a small whole just alittle ways from the corners, all the way around. Then I put some crisco shortening inside the case to attract shb,and squirt some Fipronil all around the crisco. Place case on top of inner cover, and every few weeks take the telliscoping lid off and empty the dead SHB's out off trap. Also have SBB with a plastic box under it with used cooking oil and apple cider vinegar about 1/4 inch deep to catch those that fall. Haven't seen as many lately.
