Nest are usually located in dark, humid and wet areas close to food and water sources. Place near air conditioning units, garbage cans, along walls and window sills. Several interesting points to consider when dealing with outdoor ant control. First, ants continually move from treated areas to untreated areas. The widely use of mulch and plants around structures allows ant nests to survive even powerful sprays.
Sprays often can t penetrate the layers of mulch to reach the ants.
Excessive rain caused ants to be more mobile and often times seek shelter in structures. Different areas having different species of ants makes it easier when a bait has the ability to be attractive to the ant s sweet or protein preference. Apply gel in spots or dabs, the size of a dime, in cracks and crevices. Gel can be placed in any out of the way place. Application within food areas is limited to crack and crevice treatment only if the areas are not routinely washed.
