Cockroaches (roaches) are insects that adapt easily to any
environment; however, they prefer to dominate an area within a building that is warm and has easy access to food. Worldwide, there are over 4,000 species of cockroaches; however, fewer than 30 are considered pests.
In Britain there are three species that are native to our country however it’s the German Cockroach and the Oriental Cockroach that are the pests, these ‘roaches’ were introduced to our country accidently.
Cockroaches like to live underground, but if a cafe, restaurant, take-away, hospital, or your home has bad hygiene practices, they can be found under dishwashers, cookers, and refrigerators. These pests mark their territory by sending out chemical trails in their feces. This helps with mating and marking out food sources. Once they mate, the female will lay her eggs in food deposits.
Once you have an infestation of Cockroaches they can spread microbes that are potentially harmful to humans and have been linked to causing asthma attacks in some people. 
Getting rid of Cockroaches can be a dangerous operation if you were to try it yourself.
Seeing cockroaches in your premises is both up-setting and potentially damaging to your business, there are many ways to exterminate these pests but the best way by far is to contact a reputable Pest Control Company this will save you time, money and embarrassment .
