American cockroach adults grow to an average length of around 4 centimeters (1.6 in) and about 7 millimeters (0.28 in) tall. They are reddish brown and have a yellowish margin on the body region behind the head. Immature cockroaches resemble adults except that they are wingless. The insect can travel quickly, often darting out of

The German cockroach (Blattella germanica) is a small species of cockroach, measuring about 1.3 cm (0.51 in) to 1.6 cm (0.63 in) long; however, they are known to get bigger. They can be tan through brown to almost black, and have two dark parallel streaks running from the head to the base of the wings.

The oriental cockroach (also known as: waterbug and Blatta orientalis) is a large species of cockroach, measuring about 1 in (2.5 cm) in length at maturity. It is dark brown to black in color and has a glossy body. The female Oriental cockroach has a somewhat different appearance to the male, appearing to be wingless

According to research published in Insectes Sociaux in 2009, it was discovered that ants from three Argentine ant supercolonies in America, Europe, and Japan, that were previously thought to be separate, were in fact most likely to be genetically related. The three colonies in question were one in Europe, stretching 6,000 km (3,700 mi) along

The pavement ant, Tetramorium caespitum, is a common household pest. Its name comes from the fact that colonies usually make their homes in pavement. It is distinguished by one spine on the back, two nodes on the petiole, and grooves on the head and thorax. The species is native to Europe, but was introduced to

Spiders (order Araneae) 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. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every habitat

Indian meal moths (Plodia interpunctella) are the most common pantry pests. Adult meal moths are about a half-inch in length and have bi-colored wings that set them apart from clothes moths and live long enough to mate, usually about a week. The larvae become whitish caterpillars with brown heads that hatch and feed in cupboards

A moth is an insect closely related to the butterfly, both being of the order Lepidoptera. Moths form the majority of this order; there are thought to be 150,000 to 250,000 different species of moth (about ten times the number of species of butterfly), with thousands of species yet to be described. Most species of

Bees are flying insects closely related to wasps and ants, and are known for their role in pollination and for producing honey and beeswax. Bees are a monophyletic lineage within the superfamily Apoidea, presently classified by the unranked taxon name Anthophila. There are nearly 20,000 known species of bees in seven to nine recognized families,

Flea is the common name for insects of the order Siphonaptera which are wingless insects with mouth-parts adapted for piercing skin and sucking blood. Fleas are external parasites, living by hematophagy off the blood of mammals (including bats and humans) and birds. 

 Fleas are wingless insects (1/16 to 1/8-inch (1.5 to 3.3 mm) long)

Crickets, family Gryllidae (also known as “true crickets”), are insects somewhat related to grasshoppers, and more closely related to katydids or bush crickets (family Tettigoniidae). They have somewhat flattened bodies and long antennae. There are about 900 species of crickets. They tend to be nocturnal and are often confused with grasshoppers because they have a

Earwigs make up the insect order Dermaptera, found throughout the Americas, Eurasia, Australia and New Zealand. With 1,800 species in 12 families, they are one of the smaller insect orders. Earwigs have characteristic cerci, a pair of forceps pincers on their abdomen, and membranous wings folded underneath short forewings, hence the scientific order name, “skin
