How to get rid of this?
To get rid of a cockroach problem, inspection is the first and foremost step.
Cockroaches can measure over 50 mm (2 in) length, with tropical species tending to be larger than those found in other climates. Cockroaches have six legs, two antennae and some have wings.
They can hitch a ride on infested items brought inside, get indoors via cracks and gaps in the home’s exterior, enter through drains or sewer pipes and a few species of cockroaches can fly inside when attracted to lights.
