I’d start with once a week for four weeks (as suggested in my post) and see how it goes.

Thanks,

Ants are easy.
1 tbs of any kind of sweetener (cheap syrup, sugar, honey, etc.).
1/2 tsp or a little more of 20 Mule Team Borax or boric acid.
3 tbs warm water.
Stir until all are dissolved.
Set it out in a shallow lid (a water bottle cap is good enough) and let the ants feed all they want. Don’t be tempted to kill them no matter how many show up. The idea is to give them time to take the mixture back to their nest and feed the rest of the population. In less than two weeks they’ll be gone. I’ve seen where they’re gone in one day. If this is done in the spring you probably won’t see any more ants for the rest of the year. Don’t go crazy with this and kill all the ants around your house. You’ll be opening yourself up to termites. Just feed the ones that come into your house.
