In Brazil, the tiny micro-sized ant is a constant source of irritation. For many years I tried every kind of powder, spray and cream available and still watched in awe as a tiny morsel of cat food would immediately produce hundreds of these creatures literally parading from tiny spaces in the walls. THEN, I found TERRO while shooping at a Target in the USA and brought it back to test. At first I put out 5-6 of the nice little "houses." and watched all the parades for several weeks. Now, a year later, once again in "bug" season, I have seen only 3-4 ants and just have traps in the kitchen and bathroom. These baits are:
1-very easy to use...just cut off a tiny door at the designated place
2-can easily be put in locations where children and pets cannot reach and still be effective
3-do not cause any odor, drips, or leave messy traps to clean up. Just throw away when liquid is gone.
