Please help me deal with these single-minded ants.
These tiny golden brown ants
do not want water, sugar, fabric, wood (as far as I can tell; they certainly do not want paper or cardboard), plastics, or starch/vegetable matter.
They are also completely disinterested in Borax or Terra - I put out five of them, one or two ants went in and got stuck in it, everybody else ignored them.
These ants want fat, and nothing but fat. Drop a little crumb of butter on the counter, and it will be covered in half an hour. Leave a greasy plate in the sink overnight, they will get in it. The dogs* can only have their food set out for a few minutes and we have to pick up any stray kibbles that get dropped immediately, or they will be covered in a few minutes. We're keeping the bag in a chair, which has worked so far. The ants also enjoy high-quality moisturized toilet paper, which is bad enough, but this morning I found them trying to get into my $50 tub of Lush lotion and oh hell no.
They're in the walls. One particular kitchen wall for sure, plus the central wall in the house, and they appear to have come for the lotion out of the electrical outlet.
So far they have ignored butter or peanut butter with borax in it, and like I said they ignored the Terra stations, and also some Raid ones. They're more interested in a greasy fingerprint than any of those things. I'm willing to try again with different Borax ratios - I used quite a but last time, maybe it was too much.
Our landlord's solution to most problems is either ignore us or come coat our house and yard in random poisons without discussing with us, so we'll be handling this ourselves. It's a single story freestanding ranch house in San Diego, built in the late 70s.
I'm not even sure they can be eradicated; I suspect this is the kind of colony that has multiple queens. But if we can reduce or discourage, that might at least be a moderate victory. Any suggestions would be welcome.
