The Tiger Centipede (Scolopendra polymorpha), also called the Common Desert Centipede or Banded Desert Centipede, is the most frequently encountered large centipede across Arizona and the broader Sonoran Desert region. It reaches 3–5 inches in length and is highly variable in color — ranging from tan and olive to reddish-brown, often with banded or striped legs that give it its common name. It has 21 pairs of legs and is a fast, agile predator of insects, spiders, and small lizards. The Tiger Centipede is found under rocks, in soil crevices, beneath bark, and in desert debris. It is primarily nocturnal and most active during warm months, especially after rain. While its bite is painful and can cause localized swelling, it is generally less severe than that of the Giant Desert Centipede. It occasionally enters homes, garages, and sheds in search of prey or moisture.
👁Warning Signs
Medium-large (3–5 inch) banded or striped centipede found under rocks, bark, and debris. Nocturnal — most sightings at night. Enters garages, ground-floor rooms, and sheds. More active after rain. Fast-moving when disturbed.
⚠Health & Property Risks
Bite causes moderate to significant localized pain and swelling. Symptoms typically resolve within a few hours to a day. Allergic individuals may experience more pronounced reactions. Avoid handling — it moves quickly and bites readily when threatened.
Prevention Tips
Remove rock piles, bark mulch, and debris from the home perimeter. Seal foundation gaps, door gaps, and pipe penetrations. Install door sweeps. Reduce moisture near the structure. Minimize outdoor lighting that attracts prey insects at night.
🛡Professional Treatment
Perimeter residual treatments targeting harborage areas. Pest Control Bros identifies and treats rock piles, landscape timbers, and other harborage zones while sealing key entry points. Prey insect control is addressed simultaneously to remove the food source drawing centipedes to the structure.

Often, yes. Centipedes are predators — they follow their food supply. Finding tiger 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.
