Nymph of assissin bug - camouflaged with debris |
Adult
Assassin Bug |
The masked hunter, Reduvius personatus (L.) is an introduced European species that is now widespread. The common name is derived from the habit of the nymph "masking" itself with fragments of foreign matter, such as dust and lint. The dust particles are attached to long fine hairs and provide camouflage for the nymphs, which are commonly found in dusty corners of the house or barn.
The adult assassin bug is a nearly uniformly dark brown to almost black elongate-oval bug. It varies in length from 17-22 mm. Most species are very active and fly well. At night they are attracted to artificial light.
Both adult and nymphs are predaceous, with piercing-sucking mouthparts. They feed on other insects and are therefore considered beneficial. However, if handled roughly or crushed, often, in self-defence, they will inflict a painful bite to humans. The bite is similar to a bee sting and is often followed by numbness and swelling. In most cases there appears to be only one generation a year.
Adequate screening should be used since assassin bugs are attracted to lights. Use a vacuum to remove any of these bugs that are found indoors. If required, a general-purpose insecticide, recommended for indoor use, can be used as a spot treatment.
