Current Pest Advisory for Montebello Hills (August 2026)

As August heat bakes the Montebello Hills, the two pests most likely to invade your home are Argentine ants and roof rats. The hot, dry weather drives ants to seek moisture, and the hillside terrain with its decomposed granite and clay soils concentrates water runoff near lower foundations, creating ideal conditions for ant trails to enter slab-on-grade homes. Meanwhile, roof rats are active year-round but become more noticeable in summer as they forage for food and water; your mid-century modern and contemporary homes with stucco exteriors and sealed attics offer plenty of gaps around roof vents and eaves for these agile rodents to exploit. The native chaparral on the slopes provides excellent harborage and food sources, so rats and ants are never far from your property. Look for ant trails along foundation edges, especially near downspouts and areas where runoff pools, and check for rat droppings in attics or along rooflines, plus gnaw marks on vents or wires. Also, inspect for foundation cracks that may have developed from soil shifts after heavy rains, as these can become entry points for both pests. Below are the top-rated Montebello exterminators who specialize in these specific seasonal threats.
