San Diego Centipede: Identification, Habitat, and Control
The San Diego Centipede (Scolopendra viridis) is a large, venomous centipede species found in Southern California, including the San Diego area. Known for their fast movement and painful bite, understanding their characteristics and habitat is crucial for effective prevention and control.
Identification and Physical Characteristics
The San Diego Centipede, a member of the Scolopendra genus, typically ranges in size from 4 to 6 inches in length. They are characterized by their flattened body, numerous legs (one pair per body segment), and a pair of venomous claws called forcipules located just behind the head. Coloration can vary, but they often exhibit shades of brown, orange, or greenish-yellow, sometimes with darker bands along their body segments.
Habitat and Behavior
These centipedes are nocturnal predators, preferring dark, moist environments. Common habitats include under rocks, logs, leaf litter, and in crevices within soil. They are often found in gardens, yards, and occasionally within homes, especially in areas with high humidity. As carnivores, they prey on insects, spiders, and even small rodents.
Are San Diego Centipede Bites Dangerous?
While the San Diego Centipede is venomous, its bite is typically not life-threatening to humans. The bite can be intensely painful and cause localized swelling, redness, and numbness. Symptoms usually subside within a few hours to a few days. However, individuals with allergies or weakened immune systems should seek medical attention if bitten.
Prevention and Control
Preventing San Diego Centipedes from entering your home involves reducing their potential habitats. Here are some tips:
- Seal cracks and crevices in foundations and around windows and doors.
