Hi if you want to get rid of the ants you need to get rid of the Queen, there is a product that will get rid of them by the next day guarantee. Here in Florida under slab termite treatment is required prior to pouring a home slab, and final exterior perimeter treatment is required by building codes, in order to get a building final certificate of occupancy.
The product of choice by professional exterminators is (Termidor sc) it is the best out there as far as I'm concerned, it does not smell and has years of shelf life, I buy it in 2.5 gallon containers that run around $600 + and I would not pay that much if the product was not the best, you can buy 20 oz at DO MY OWN PEST CONTROL.com and also eBay, for around $50.00 with free shipping, a 20 oz concentrate container will make 25 gallons that's $2.00 a gallon for the best product out there.
I was paying $ 800 to 1200 per home every few years for a not well done diluted treatment, so I built my own copper injecting rods, purchased a pump, hose and a 100 gallon tank to do my own treatment for injecting the ground and killing subterranean termites in my rental houses, I can tell you that every time I have used it the ants disappear by the next day. I have been using the product for over ten years and have witnessed the 10 year guarantee that they claim it has.
