Unless the cover has a bee space recess, ants (and other insects) will move into the cover/inner cover space.
Looking again at the descriptions of the inner covers in my original post, #2 should only be used if the 3/8" bee space side is down?
Can someone please explain the use of inner covers as the seasons change? Isn't one side supposed to go up in the summer and the other side goes up in the winter? (sorry if that's a dumb question) Which side is which? And, of the two inner covers listed in my original post, which one is the better to have?
