They seem to congregate in a small area on the living room floor, so I scattered the entire four-pack of traps around their hangout. Sunday, I checked in on my visitors to see how they were doing: I noticed that (1) there were more, but (2) they were all motionless.
SUCCESS! ...Or so I thought, until I tapped the floor to see what was up, which had the effect of instantly rousing them all from their stupor, to immediately begin busily doing their ant-things. Including not going into the traps.
(But maybe that's all the poison does? Stuns them into stasis for a while to make them easier for me to squash?)
This morning, they're still there. The same ones? Different ones? I confess, at the risk of sounding species-ist, that they all look the same to me, so I'm really unable to gauge what's going on.
I'm thinking I oversaturated the market, so maybe I should get a few different brands of traps, to provide some variety for their dining choices. (This assumes, of course, that there's an effective way to make waxy, brownish insecticide appear to be a healthy and delicious thing to eat.) Or, maybe these traps are the ant equivalent of Denny's.
