What’s bugging you? Click on the appropriate image to identify your pest. Cockroaches are insects of the order Blattodea, sometimes called Blattaria, of which about 30 species out of 4,600 total are associated with human habitats. About four species are well known as pests. Spiders are air-breathing arthropods that have eight legs, and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other groups of organisms. Ants are social insects of the family Formicidae that belong to the order Hymenoptera. They are easily identified by their elbowed antennae and a distinctive node-like structure that forms a slender waist. Silverfish or fishmoth, is a small, wingless insect in the order Thysanura. Its common name derives from the animal’s silvery light grey and blue colour, combined with the fish-like appearance of its movements, while the scientific name (L. saccharina) indicates the silverfish’s diet of carbohydrates such as sugar or starches. Earwigs got their name from the myth that they crawl into sleeping people’s ears and tunnel into their brains. The long cerci, or clippers, on their backsides easily identify an earwig. Millipedes are arthropods that have two pairs of legs per segment (except for the first segment behind the head which does not have any appendages at all, and the next few which only have one pair of legs). Each segment that has two pairs of legs is a result of two single segments fused together as one. Centipedes are arthropods belonging to the class Chilopoda of the subphylum Myriapoda. They are elongated metameric animals with one pair of legs per body segment. Despite the name, centipedes can have a varying number of legs from under 20 to over 300. A wasp is any insect of the order Hymenoptera and suborder Apocrita that is neither a bee nor an ant Bed bugs, bed-bugs, or bedbugs are parasitic insects of the cimicid family that feed exclusively on blood. Cimex lectularius, the common bed bug, is the best known, as it prefers to feed on human blood. Other Cimex species specialize in other animals, e.g., bat bugs, such as Cimex pipistrelli, Cimex pilosellus, and Cimex adjunctus. Fleas are the insects forming the order Siphonaptera. They are wingless, with mouthparts adapted for piercing skin and sucking blood. Fleas are external parasites, living by hematophagy off the blood of mammals and birds. Ticks are small arachnids in the order Parasitiformes. Along with mites, they constitute the subclass Acarina. Ticks are ectoparasites, living by hematophagy on the blood of mammals, birds, and sometimes reptiles and amphibians.
