Centipede Control In Alexandria VA

Centipedes in Alexandria VA

Centipedes are predatory arthropods belonging to the class Chilopoda of the subphylum Myriapoda, an arthropod group which also includes millipedes and other multi-legged creatures. Centipedes are elongated segmented (metameric) creatures with one pair of legs per body segment. All centipedes are venomous and can inflict painful bites, injecting their venom through pincer-like appendages known as forcipules. Despite the name, centipedes can have a varying number of legs, ranging from 30 to 382. Centipedes always have an odd number of pairs of legs; no centipede has exactly 100 legs. Like spiders and scorpions, centipedes are predominantly carnivorous.

Their size can range from a few millimetres in the smaller lithobiomorphs and geophilomorphs to about 12 in in the largest scolopendromorphs. In Alexandria VA and the surrounding areas, they rarely get to be more than a couple inches long.

Centipedes can be found in a wide variety of environments. They normally have a drab coloration combining shades of brown and red. Cavernicolous (cave-dwelling) and subterranean species may lack pigmentation, while many tropical scolopendromorphs have bright aposematic colors.

Worldwide, an estimated 8,000 species of centipedes are thought to exist, of which 3,000 have been described. Centipedes have a wide geographical range, even reaching beyond the Arctic Circle. They are found in an array of terrestrial habitats from tropical rainforests to deserts. Within these habitats, centipedes require a moist microhabitat because they lack the waxy cuticle of insects and arachnids, therefore causing them to rapidly lose water. Accordingly, they are found in soil and leaf litter, under stones and dead wood, and inside logs. Centipedes are among the largest terrestrial invertebrate predators, and often contribute significantly to the invertebrate predatory biomass in terrestrial ecosystems.

House Centipedes in Alexandria VA

The house centipede, believed to have originated in the Mediterranean region, was introduced into Mexico and the Southern United States and has increased its distribution. It spread to Alexandria VA sometime before 1849, when it was discovered to have spread to Pennsylvania. Today, the house centipede can be found in many buildings throughout the United States. It does not do particularly well outdoors in the winter in Alexandria, but readily reproduces in heated structures.

Because of their secretive nature, scary appearance and darting motions, homeowners typically fear the house centipede. In 1902, C.L. Marlatt, an entomologist with the United States Department of Agriculture wrote in Circular #48 - The House Centipede: "It may often be seen darting across floors with very great speed, occasionally stopping suddenly and remaining absolutely motionless, presently to resume its rapid movements, often darting directly at inmates of the house, particularly women, evidently with a desire to conceal itself beneath their dresses, and thus creating much consternation." Undoubtedly, the current favor of blue jeans as a preferred article of clothing has not appreciably reduced the angst felt by the household "inmates" when a centipede is seen scurrying across the basement floor.

House Centipede Bites - Should I Be Worried?

The most common centipede found in Alexandria VA is the house centipede (Scutigera coleoptrata), which is the only species of centipede known to reproduce in homes. While house centipedes can inflict a bite, it is of minor consequence and it rarely does so. When given the chance, house centipedes prefer to quickly retreat from danger rather than bite. Typical symptoms from a house centipede bite are slight pain and swelling as their weak jaws rarely allow them to break skin.

Biting Centipedes In Alexandria VA

Centipedes bite in order to defend themselves and to capture their prey. Centipedes use a pair of hollow legs, adapted with claws, to bite into the skin. These pincer-like maxillipeds, also known as toxicognaths or "poison claws," are found under the first body segment and can also cause small puncture wounds and blisters when the centipede crawls across the skin. When a centipede bites (as opposed to stings), it injects venom into victims that is stored in internal glands. Although centipede bites may be painful, they are rarely fatal.

The symptoms of centipede stings vary depending on the degree of allergic reaction and the size of the centipede. Typically, bite victims have severe pain, swelling and redness at the site of the bite, with symptoms usually lasting less than 48 hours. Symptoms for those more sensitive to the venom’s effects may also include headache, chest pain, heart tremors, nausea and vomiting.

Victims from centipede bites are often gardeners. The venom administered through a centipede bite is typically harmless, not life threatening to humans and symptoms are fleeting, lasting only a few hours. However, the larger the specimen, the greater the pain will be. Small children and individuals with known insect allergies may experience more severe reactions. Always contact a physician for advice and treatment of centipede bites.

Centipedes Poisonous In Alexandria VA?

The most common type of centipede in Alexandria VA, house centipedes sting with appendages called forcipules and administer a venom to subdue their prey. However, because of their size when compared to humans, this venom poses virtually no risk to humans if they are stung. Most people who are stung by centipedes experience a little bit of redness and slight swelling in the area, but those people that are allergic to bee stings might have a more severe reaction if anaphylaxis occurs.
