Ants love this or hate it depending on your perspective. I had a problem with tiny ants......not serious but very annoying. Placed these packets strategically around my home where ants were seen milling about. You see increased activity as the ants are drawn to its syrup. I suppose they consume the poison and wither away to die. What I don't understand is how the other ants know not to come....is there a secret SOS signal that is sent out in the air waves that humans can't hear. Anyway...after a few days...no more ants. It's very important to place them where ants seem to congregate to be effective. The more the better. Kitchen and bathroom were my problem areas. Would highly recommend this product.
