Hello all: I got some borax laundry additive two weeks ago. I think my wife said it was less than $5 for five pounds. Well I mixed 1/1 syrup with about 1/2 part borax. Got a super saturate solution had some on the bottom. Put some in a small pickle jar about 1/4 full. Put some 16d nail holes in the lid. Set it on its side at about 30 deg. under the hive. In a couple of hours it was killing ants. They go in the jar and never come out. Bees can't get in so it seems to be O.K. Thank you Don Bowen. Later JRT
