In the UK we have two main cockroaches species. We have the German Cockroach which is approx 12-15mm long and ranges from light to dark brown. We also have the bigger Oriental Cockroach which is approx 20-30mm long and dark brow/black in colour. Cockroaches are generally nocturnal (active at night) and will stay hidden until its time to feed. As such, you don't often see them but may notice other signs such as a musty, oily odour or their droppings which are brown/black and approx 2mm in length. If you think you have cockroaches, contact us for your affordable treatment options.
