I've never seen anything like this, and the help line at Raid! was puzzled too. Anyone else ever have this problem?
There must have been an Ant Armageddon somewhere near or under our master bathroom floor. Every morning for four days we've been vacuuming up hundreds of tiny dark brown and very dead ants both IN our shower and just outside it. I think the ants are bringing out their dead. I'd like to think this is tapering off. This morning I don't see *any* live ants, and there are only a couple dozen dead ones.
I'm guessing these are 'cement ants'. They are completely disinterested in the ant baits I put down 48 hours ago. They aren't interested in the shower drain. I can't see any nest in the basement.
