I live in a place that has TONS of brown running ants, following ants or whatever they are called. They really attack the nymphs but will also go after the adults. On the plus side I found around 500 babies while cleaning out the bins! Where would I put the vasaline, towards the bottom of the bin? I hate using that stuff....makes a mess! I think that maybe better then using water, but does vasaline dry up? I can't use the bigger bin idea, I'm using 50gallon rubbermaids. I need to produce tons of roaches!
