The intice bait stations would be a great option for outdoor bait control for ants. It may be more beneficial for you to find out what species of ant you are dealing with prior to treating but the Intice Stations will work with most ants. An average home would use a minimum of 4 stations (one at each corner of the house), but if you are experiencing extremely high numbers of ants you may need at least 6-8 to completely meet the needs of the ants. Another way to treat the ants would be with a non-repellant spray like
Dominion 2L. It covers a large range of pests on the label but does an exceptional job on ants. You would spray the dominion 2 feet up and 2 feet out around the foundation of the home. Any ant that comes into contact with a surface you sprayed it on, would pick the product up on their skin unknowingly and transfer it to every other ant it came into contact with. The Dominion has a delayed kill which allows it to have a great spread rate through the colony and insure the entire colony is eliminated, and it doesn't require bait acceptance for it to work. Either option would be a great choice, and if you have more questions feel free to contact us at 1-866-581-7378 as we could give more direct instructions on your situation over the phone and better assess your homes needs.
