I use FGMO and smear it around the bottom boards and this has worked great keeping the ants out. I'm reapplying either tomorrow or the day after. I did a partial swipe with my finger today and they were getting thin, so I'll reapply. We had our first rain in a long time last night, too heavy, and some was washed off. It lasts for quite a while and stands up to medium or less rain. The bees stay away from the FGMO and the ants don't get in from the outside. With a SBB the bees keep them out from coming in. I've watched the guard bees bite the devil out of 'em. :D
As far as how long I'll need to go back to my notes and see if I wrote it down. I had better have.
With SHB I learned how to bait them in. Leave your protein patties on too long and they love you for it and start to trash a newly installed package. :evil: As I write this I wonder if you can't set up a bait trap like the yellow jacket/wax moth traps? :?:
