With great adaptability and survival skills, cockroaches thrive in warm, humid, urban environments. They are drawn to food sources and areas that are dirty, sticky, or damp. A vast range of material can be sourced as food, including cardboard, glue, and faeces. Cockroaches are known to hide inside cupboards, under fridges or in ceilings and are deterred by bright lights; this is why their eggs are often difficult to spot.
A cockroach infestation is irritating as they not only lay a single egg, but multiple at once. On average, an egg case can lay about 40 cockroaches. So, if you’ve seen a cockroach crawling around your home, there is a good chance that plenty more are hiding in dark areas of the house.
