Current Pest Advisory for Sparr Heights (August 2026)

As August heat settles over Sparr Heights, the dry, warm conditions are driving two pests into homes: Argentine ants and roof rats. The ants, thriving in the 80s-90°F weather, are seeking moisture and food, exploiting the damp zones created by irrigation runoff near foundations—a common issue on the gentle slopes of this foothill neighborhood. Your mid-century home's raised foundation and crawlspace provide ideal entry points, especially along the tree-lined streets near the Sparr Heights Community Center. Meanwhile, roof rats are active in the mature oaks and parkland adjacent to the Verdugo Mountains, using branches that overhang roofs to access attics. The abundant acorn crop from these oaks is a primary food source, and the older homes' original construction often has gaps around eaves and vents that rats can exploit. Look for ant trails along pipes and foundation edges, and for rats, check for droppings in the attic, gnaw marks on wires or wood, and sounds of scurrying at night. Also, inspect for greasy rub marks along rooflines and fence tops, and be alert for burrows near the foundation or under the community center's landscaping. Below are the top-rated Glendale exterminators who specialize in these specific seasonal threats.
