Contains a very effective ant killer with a bait that is attractive to ants. It's easy and convenient way to control ants both indoors or outdoors; just place the traps wherever you see ants and punch all side holes. Ants enter traps and carry the 'food' back to the nest; an entire colony is usually destroyed in 7-10 days. For outdoor use; place traps near ant hills on lawn or garden. Do not remove the lid of the container. The special formula keeps bait permanently fresh in traps; there is no messy bait exposed on indoor surfaces. They are clean and easy to use.
