House Centipedes: What to Know

Check out this answer from Consensus:

House centipedes, while often perceived as pests themselves, offer significant benefits in pest control and potential medical applications. Their ability to manage household pest populations naturally and the discovery of bioactive compounds like scolopentide underscore the importance of these arthropods in both ecological and medical contexts. Understanding and appreciating the role of house centipedes can lead to more informed and balanced perspectives on these fascinating creatures.

House centipedes, scientifically known as Scutigera coleoptrata, are common arthropods found in many households. Despite their alarming appearance and rapid movements, these creatures play a significant role in controlling pest populations. This article delves into the biology, behavior, benefits, and potential medical applications of house centipedes.

Biology and Behavior

House centipedes are elongated, multi-legged arthropods that can grow up to 1.5 inches in length. They possess 15 pairs of long, slender legs, which allow them to move quickly and capture prey efficiently. These nocturnal hunters primarily feed on insects, spiders, and other small arthropods, making them beneficial for pest control in homes.

Benefits of House Centipedes

One of the primary benefits of house centipedes is their role in natural pest control. By preying on common household pests such as cockroaches, ants, and termites, they help reduce the need for chemical pesticides. Their presence can be an indicator of a healthy ecosystem within the home, as they help maintain the balance of insect populations.

Medical Applications

Recent research has highlighted the potential medical applications of centipede-derived compounds. For instance, a study on the centipede Scolopendra subspinipes mutilans identified an antihepatoma peptide called scolopentide. This peptide has shown promising results in inhibiting the growth of liver cancer cells (HepG2) through apoptosis, a process of programmed cell death1. The study demonstrated that scolopentide activates death receptors DR4 and DR5, leading to the induction of apoptosis in liver cancer cells via a mitochondria-independent pathway1.
