Knowra German cockroach German cockroach The German cockroach (Blattella germanica) is a small, fast-breeding cockroach that lives mainly in human buildings. It is a persistent household pest with unusual egg-case care and strong resistance to many insecticides.
Ootheca : A protective capsule containing insect eggs, produced by cockroaches and several other insect groups. The female carries this egg case until shortly before the young hatch.
Cockroach control : Methods used to prevent, monitor, and reduce cockroach populations in buildings and other environments. This broader practice includes the sanitation and baiting approaches used against German cockroaches.
American cockroach : A large reddish-brown cockroach, Periplaneta americana, common in warm buildings and sewer systems. It is much larger and more often associated with drains and basements.
Carl Linnaeus : A Swedish naturalist who established the system of binomial nomenclature used to name species. Linnaeus formally described Blattella germanica in the eighteenth century.
Nymph : An immature insect that resembles its adult form but lacks fully developed wings and reproductive organs. German cockroaches pass through several nymph stages before adulthood.
Gel bait : An insecticide formulation placed in small amounts where insects forage, often consumed as food. Gel baits can reach cockroaches in concealed indoor harborages.
Oriental cockroach : A dark, glossy cockroach, Blatta orientalis, often found in cool, damp areas. Its darker appearance and preference for damp sites distinguish it from the indoor German cockroach.
Blattella : A genus of small cockroaches that includes Blattella germanica and related species. The German cockroach belongs to this genus of closely related small cockroaches.
Insecticide resistance : The inherited ability of an insect population to survive doses of insecticide that once controlled it. Resistance to multiple insecticide classes makes control less reliable.
Sticky trap : An adhesive device used to capture insects and monitor their presence and movement. Trap counts help locate German cockroach harborages and assess control progress.
