I had a pretty bad carpenter ant problem... was seeing dozens of them every day. I applied Termidor about 2 feet up the foundation and 2 feet out onto the dirt soil. It's been a week and I still see them, although I've noticed they're not showing up in such high numbers. Generally, how long should it take until they completely disappear? I've heard some people say 24 hours and others say several weeks.
When using Termidor SC to treat carpenter ants it may take anywhere between 30 to 90 days to eradicate the colony. Termidor kills by transfer. The foraging ants will come out and make contact with the active ingredient. The kill is delayed long enough for the ant to transfer the active ingredient throughout the colony producing a domino killing effect and ultimately killing the queen.
