Pests We Treat Case Studies: Ants in Wall, NJ Home are Persistent

Monday, May 4th, 2015 by Tom Hayes


Cowley's received a call from a Wall homeowner for an ant infestation in the kitchen and living room. Ants are social insects that live in colonies. For long-term results, the colony must be eliminated. Killing isolated ants with a repellent spray is ineffective. This technician used an Inside/Outside treatment plan for this ant infestation after determining that the ant colony was outside the home and scent trails were established for inside foraging. Ants typically enter homes through small openings, often minuscule cracks in the foundation, foraging for water or food, either sugars or proteins, leaving a pheromone trail for others to follow. To find the ant nest, a technician must follow the trails.


For this ant infestation, the technician first treated the inside of the home. He spot-treated the baseboards in those areas of observed ant activity. Afterwards, he applied a residual aerosol around the windows. Residual aerosols are applied to surfaces and remain active for an extended time after the application to kill insects as they come into contact with the treated area. Shortly after treatment, the technician observed a large number of ants emerging from under the windowsill.

After completing the interior treatment, the technician treated the home's exterior along the foundation. During the exterior treatment of this home, the technician observed an ant trail going up the foundation and into the home.
