Ants and crawling insects can be unwelcome visitors to homes and gardens, but Nippon has the solution to controlling them as quickly as possible. Nippon Ant Bait is highly attractive to black worker ants which collect the bait to feed the queen and other ants in the nest. The bait builds up within the colony and the entire nest is usually eliminated in 7 to 10 days. Baits are discreet and can be used indoors or outdoors.
