Soil Centipedes (Geophilus flavus and related species in the order Geophilomorpha) are elongated, worm-like centipedes adapted for life in soil and leaf litter. They are pale yellow to light brown, extremely slender, and can reach 1–3 inches in length with 31 or more pairs of legs — the exact number varies by species and individual. Unlike the large Scolopendra centipedes, Soil Centipedes are entirely subterranean in habit, spending their lives burrowing through soil in search of earthworms, insect larvae, and other soil organisms. They lack functional eyes and navigate entirely by touch and chemical senses. They are almost never seen above ground except after heavy rain flushes them to the surface. Soil Centipedes are completely harmless to humans — their forcipules are far too small and weak to penetrate human skin, and they have no interest in entering homes. Their presence in garden soil is generally beneficial.

Often, yes. Centipedes are predators — they follow their food supply. Finding soil centipedes indoors frequently suggests an underlying population of the insects and arthropods they hunt: cockroaches, silverfish, spiders, ants, or other small invertebrates. Pest Control Bros will inspect for both the centipedes and the prey species driving them indoors, addressing the root cause rather than just the symptom.
