This August, Toluca Woods homeowners should be on high alert for roof rats and Argentine ants. The hot, dry weather is driving roof rats out of the Tujunga Wash and industrial zones, seeking water and cooler shelter. Your 1950s and 1960s tract homes, with their stucco exteriors and poorly sealed attics, are prime targets—rats can squeeze through gaps the size of a quarter, especially where utility lines enter. Look for droppings in the attic, gnaw marks on roof beams, or scurrying sounds at dusk. Argentine ants, meanwhile, thrive in the dry conditions, marching in long trails from sandy soil into kitchens in search of moisture. Check along the foundation and under composition shingles for ant trails, and be vigilant near the Bob Hope Airport flight path, where the open spaces provide ant colonies with abundant food sources. As the heat persists, these pests will only become more aggressive, so early detection is key.

To protect your home, inspect the roofline for overhanging tree branches that could serve as bridges for rats, and seal any cracks in stucco or around vents. For ants, eliminate standing water and wipe down counters to remove food odors. The sandy soil around your property drains quickly, so consider using gel baits that retain moisture. If you notice any of these warning signs, act promptly to prevent infestations from spreading. Below are the top-rated North Hollywood exterminators who specialize in these specific seasonal threats.
