Bests & Worsts Reviews from Amazon

I cannot believed the formula was changed. I bought this last summer of 2017 and rated it as one the best ant killing products I had ever used. Last summer any place I distributed the product would be swarmed by ants in a couple of minutes and a couple of days later ants were gone. They must have changed the recipe for this year. Ants no longer swarm on the product as they did last year and ants return quickly. I would not buy again unless I hear they go back to last year's formula. What a disappointment.
