From Guardian's FAQ,"
1.) **Can the Guardian be left on all year: We do not recommend leaving the Guardian on the hive at temperatures below 40 F - Hive beetles are not active below this temperature and damage may occur to the Guardian
2.) **Can the Guardian be used as a mouse guard: The Guardian was not designed to be a mouse guard and significant damage may result."

I use screened bottoms and oil pans to manage SHB in 3 Langstroths and a 48" long hive. The only time I have problems is when I feed patties when it's really warm. Oil pans work well and gives me a place to treat OAV from the back anytime I want.
