We carry a truly clean household in an apartment on the first floor. That has not kept us from being often "afflicted" of small black ants. Even the closing of all visible joints and cracks did not produce success. With the purchase of Envira the problem seems to be solved only once. It is fortunately true that the ant control means other than the dead ants leaves no traces. In addition, no more ants have surfaced. Conclusion: a highly effective way that delivers what it promises.
