Fireworks
Okay, what do fireworks and ants have in common you ask. Well, the 4th of July my house rocked with the sound of fireworks (and I am sure there were some illegal

ones as I could see them in the sky from my windows). The next morning (yesterday), the first visit of the ants for the summer arrived. We went out to visit friends last evening and have a nice outdoor dinner to celebrate the 4th a little late and enjoy the fact that our temperature had cooled somewhat. I came home to find them on my kitchen counter top and this morning they were on every counter surface including stove top.
I have read posts about the dangers of fireworks from the chemical standpoint because of all the particulates in the air afterwards. My theory is that between the noise and the chemicals, the ants chose my quiet and chemical free home. Why else would that suddenly appear? That’s my theory and I am sticking to it.

I had an ant invasion a month ago. I followed them back to their source. Taped the door they were walking through, poured baking soda everywhere and hydrogen peroxide on their tracks and down their holes. Alternated that with boiling water a few times a day for a few days. I was too nervous about pesticides. Poor ants. I don’t think I killed them all but managed to deter them from coming in the house. I also used some food grade diatomaceous earth outside but had someone else do that part in case I had a problem with it.
I have some diatomaceous earth. I need to put it out. They have calmed down the last day or so (knock on wood or my head).
