When using Hopguard some hives totally rip the strip s to shreds in days and have it out in front of the hive, it looks like a cattail plant (Typha latifolia) exploded. Other hives totally ignore the cardboard strip, may chew the edges a bit but if I don ' t pull it out it will be there forever . To me this is hygienic behavior also, not allowing foreign objects in the hive. I always make note of the shredders. Hopguard is very labor intensive and not my favorite product but since supers can be on and temperature doesn't effect application I use it on some hives.
