A number of steps can be taken by homeowners to reduce the potential for future ant problems, such as:
Store food items that attract ants, such as sugar, syrup, honey, and pet food in closed containers. Wash them to remove residues from outer surfaces.
Rinse out empty soft drink containers or remove them from the building.
Thoroughly clean up grease and spills.
Remove garbage from buildings daily and change liners frequently.
Correct roof and plumbing leaks and other moisture problems that will attract ants.
Eliminate wood-to-ground contact, such as where landscaping has pushed soil or mulch up against the wood siding of a home.
Clip back tree limbs and vegetation touching the roof or siding of the house. Limbs and branches serve as bridges between tree limb nests and the structure.
Seal cracks and openings in the foundation, especially where utility pipes and wires enter from the outside.
Stack firewood away from the foundation, and elevate it off the ground. Never store firewood in the garage or other areas of the home, as firewood is a major ant nesting area.
