There are various and unique inspection practices that can help identify stored product pest (SPP) sources. For one, it’s a good idea to investigate sources of old rodent bait. A variety of SPP species can use baits left behind by previous pest management providers. For accounts with ongoing SPP issues, check the attic for toss packs.
While dried flowers might be a reminder of wonderful times past, they present a tremendous opportunity for SPP infestations, especially cigarette beetles (Lasioderma serricorne). So, check dried corsages, bouquets and potpourri. Some adult beetles will search for pollen.
Living flower arrangements are an excellent source for adult dermestids, like warehouse beetles (Trogoderma variabile) and varied carpet beetles (Anthrenus verbasci). These situations can create cyclical infestations.
