I would think they would get ants...
We use the rocks, distributed about 50k of them last year at a cost of $6400 with a return of 66k in work. We just purchased 12 tons of stone for about $350 delivered this last week. 35% of all our residential work came from the bags. We hire people at piece rate 1099 to make them. Each 5k batch costs less than $700 to produce and distribute, with an average of 20 leads and 3 complaints per batch. The high end homes tend to get the best responses. Other entrepreneurs tend to love them, so we meet a lot of very successful business owners that live in mansions the more we target those homes.
