The key to using baits is patience. Applied properly and using a fresh bait product, a broadcast application will give 80% to 90% control, rarely 100%. For instance, baits containing indoxacarb are the fastest acting, giving maximum control in as little as 3 to 7 days. Insect growth regulators, when applied late in the year, may take several months to provide maximum control, but will suppress ant colonies for a year or more.
