I emailed the below to you earlier.Carpenter ants: treat the periphery as I have (seems to have been effective thus far), consult arborist (sounds really pricey!), scream at them?
Here are a few options. These are products made especially for carpenter ants. I will add that if you treat your lawn for grubs in June using a product like Arena or one with Lamba and Mallet, you’ll not have ants. Arena kills 22 other pest aside from grubs, including ants. Listed in order of how effective I think they are.
Termidor SC (liquid) - Kills termites and carpenter ants. Treat by spraying known problems areas. Exterior use only. 20 oz bottle runs about $50.
Suspend SC (liquid) - Kills termites and ants, including carpenter ants. Exterior use only. 16 oz bottle runs $37
Adonis 2F (liquid) - 27.5 oz bottle $35
Temprid SC (liquid) - Same active ingredient as Suspend and Adonis but also with Beta-Cyfluthrin so it can be used on other pests as well in the landscape. 240 ml bottle - $65, 400 ml bottle - $72.50
While those products are designed for spot treating, they can be used to broad spray areas of the lawn and beds. Using any of the above products will not only address the carpenter ants, but will knock out any termites that might be in the area, too.
If you want to perform a granular application on the whole lawn, I would recommend applying either Merit, Arena or a Lamba-Mallet combo. The Merit is the most expensive at about $75 per bag. The Arena is about $50 per bag (many say its as good as Merit) while Lambda-Mallet would run about $35 per bag.
