Ive done the mule team borax mixed with sugar and syrup. Apparently liquids they eat themselves and solids they carry back to the colony and it takes both methods. I don’t really know why we’ve had so many less this year, but two things come to mind:

1) caulked all the cracks around the kitchen floor baseboards making it harder for them to find millions of easy paths in.

2) the Dyson handled rechargeable vacuum kept in the kitchen hung on the wall. It might be sucking the food out of the cracks in the hardwood kitchen floor unlike our endless sweeping and dustpan work.

Whatever the cause, our ant problem has been far less pervasive during this pandemic. We did also add some black plastic ant bait things that are only supposed to last a few months.

I think we also had far fewer shortly after renovating the kitchen and putting in new floors, but they came back.
