The ants are getting to be less and less. On April 4th I killed 11, on the 5th I killed 15, on the 6th I killed 7 with one huge one with wings, on the 7th I killed 13, on the 8th I killed 6, on the 9th I killed 4 coming out of the cold air return in the dining room, and only 2 this morning...I will be gone the rest of the day. Let me know if you think he needs to come back out.
