This stuff works, plain and simple. I had attempted to avoid any chemical based insecticides, but after trying dimataeceous earth and an interesting little flashlight device that emits a high pitch frequency, nothing delivered the results in a prompt manner. So I got the Terro 2oz pack and set out a few "puddles" of the stuff on the patio to get the ants hanging out in the yard and the ones that had made it in the house. The ants swarmed to the puddles and I reapplied a few days in a row. Within a week the 2 ant colonies were gone. This stuff is worth it! I need to buy a larger package next time.
