This contradicted previous understanding that the animals can develop resistance against one pesticide at a time. [99] The scientists suggested that cockroaches will no longer be easily controlled using a diverse spectrum of chemical pesticides and that a mix of other means, such as traps and better sanitation, will need to be employed.

The oriental cockroach (Blatta orientalis), also known as the waterbug (as they live in damp areas) or black cockroach (as their bodies are mostly dark), [1] is a large species of cockroach, adult males being 18–29 mm (23 ⁄ 32 – 1 + 5 ⁄ 32 in) and adult females being 20–27 mm (25 ⁄ 32 – 1 + 1 ⁄ 16 in).

Simandoa conserfariam, [1] also known as the Simandoa cave roach, [2] is a species of ovoviviparous, blaberid African cockroach that is considered extinct-in-the-wild (EW) due to human encroachment, industrial damage and pollution in their native range caused by bauxite and iron ore mining.
Blaberus discoidalis, commonly known as the discoid cockroach, [2] tropical cockroach, [3] West Indian leaf cockroach, [3] false death's head cockroach, [4] [5] Haitian cockroach, [6] and drummer, [7] is a cockroach native to Central America of the "giant cockroach" family, Blaberidae.
Blaberus giganteus is considered one of the largest cockroaches in the world, with males reaching lengths of up to 7.5 cm (3.0 in) and females 10 cm (3.9 in), [2] although others list 9 cm (3.5 in) as the maximum length. [3] These cockroaches are lightly built with flattened bodies, allowing them to hide in cracks from predators.
The Florida woods cockroach (Eurycotis floridana) is a large cockroach species which typically grows to a length of 30–40 mm (1.2–1.6 in). [2] When alarmed, adults can eject an extremely foul-smelling directional spray up to one metre (3.3 ft), [3] which inspired several of its other common names: Florida skunk roach, Florida stinkroach, skunk cockroach, skunk roach, stinking cockroach ...
Cockroaches are experts at surviving indoors, hiding in kitchen pipes or musty drawers. A new study uses genetics to chart cockroaches' spread across the globe, from humble beginnings in southeast ...
When the cockroach has recovered from the first sting, it makes no attempt to flee. The wasp clips the antenna with its mandibles and drinks some of the haemolymph before walking backwards and dragging the roach by its clipped antenna to steer it to a burrow, where an egg will be laid on it. The wasp larva feeds on the subdued, living cockroach.
