I'm looking at some plans I had for SHB traps, and they specify "combat platinum" in addition to boric acid. I checked out the MSDS for the Combat and the active ingredient turns out to be Fipronil, the same chemical as in Frontline. Now - I've found that Frontline simply doesn't do it any more for fleas, but I have some left over. Could I add that the the SHB traps instead? Or is it too strong, or too fume-y, or something, to use around bees?
