dude, do you have any idea how important ants are to the ecosystem? do not kill ants. they are a natural vaccuum system for your yard. i have black and red ants in my yard and have yet to see any in the house. i guarantee if you start killing them, other colonies will invade your house for revenge. i have seen this happen to other neighbors who had no ant infestations until they poured poison on them.

if you have ants in the house, make a dilution of peppermint oil and water. spray this solution over the threshold of infiltration. ants will not cross it. as for them being outside, leave nature alone. and you call yourself green man????
