Any bait, will only work as long as they eat it. These guys are so far
past anything in a commercial bait, it is totally useless.
I can kill them if I can just figure out what they will eat.
They got so selective that they would only eat dog food that the dog
had chewed on. I baited with that and now those ants are gone. More
came back and they won't eat that.
I did find them feeding on a dirty dinner plate but I could not figure
out what they liked. I tried to duplicate it and ... nothing.
We are finding out here in Florida that most things people "know"
about ants, may not be true. Other colonies will take in "orphan"
ants. Some colonies have multiple queens and they have multiple,
different, food streams. If one group dies, the others will not eat
that food. This place is the perfect laboratory for ants. It is a 12
month season, the ground is perfect for tunneling and we have a big
influx of exotic species.
