The carpenter ants are still be in the house. We can hear them russling the the ceiling.

I'm giving the house a second treatment with different chemicals.

The first thing I did was to tape the vacuum cleaner house up to the crack that the ants use as an entrance. I vacuumed the crack for a few minutes.

Next, I saturated the area with different, hopefully more powerful, chemicals.

If that doesn't work, I'll call in the profesionals.
