Get year-round control of house ants with Amdro ant killing bait stations. These convenient, low-profile stations contain food sources that attract a variety of ant species. That means you can kill both sweet eating and grease eating ants with one simple product. Scouting ants think the bait formula is food and haul it back to their colonies. Once the queen and other ants eat it, the colony is destroyed. Some ants die in hours, but larger colonies may take a week or more. Regardless, you can count on Amdro to get the job done.
