Infestations are common in the yard, especially along the driveway, near slab foundations or underneath large rocks, bricks or patio blocks. Though possible, they rarely build nests inside a home's walls or floors but will regularly venture inside in search of food. Small piles of dirt atop concrete cracks indicate the likely presence of a nest. Their entrances into the home can be located by following any wandering ants that you spot.
With Halloween just around the corner, its time for larger-than-life creepy, crawly creatures skittering across lawns, lurking in dark alleyways and dropping out of nowhere to frighten their hapless victims.
