Granular ant bait is a slow-acting poison which is especially effective against the queen ant. Worker ants will find the bait granules, carry them back to the nest and pass them along to the queen and other nest mates. Typically, in 1-4 weeks, the queen and a number of ants are killed and a visible reduction in activity results.
AMDRO incorporates a bait that is attractive to specific ants only. Correct ant identification will help to ensure best results from AMDRO. The following brief description of target ants will assist identification.
