There are two main species of Cockroach within Sefton – the German (Blattella germanica) and Oriental (Blatta orientalis), although at least one American Cockroach has been imported into the Borough.
- Oriental cockroaches (18-30mm) – can cope with cooler, damp conditions and are more common scuttling about in basements or drains. If conditions are tolerable they can survive outside in areas such as rubbish tips. They are not as agile as German cockroaches, but can climb a surface such as rough brickwork.
- German cockroaches (11-16mm) – need warmth and humidity to survive, so are likely to be found in and around bathrooms, laundry rooms and kitchen areas. They are also good climbers, scaling smooth surfaces like glass and polished metal with ease; due to sticky pads on their feet.
- American cockroaches (38-40mm) – although not native to the UK they have been known to be brought in via freight or luggage. Major difference of the American cockroach to Oriental and German cockroach is its ability to fly.
It may be easier to spot the signs of cockroach activity than the insects themselves. They are mostly nocturnal, hiding in cracks and crevices during the day to come out to feed at night. Cockroaches are attracted to all types of food in your home, and will eat virtually anything from food, paper to plastic packaging and animal waste (such as hamster and rabbit droppings).
There are a few signs which indicate cockroach activity
- An established cockroach infestation produces a lingering and unpleasant odour that taints items they contact.
- If little water is available cockroaches will produce brown/black cylindrical droppings, approx. 2mm long.
If you suspect a cockroach infestation you can take advantage of our assessment service where by one of our Officers will attend. They will carry out an investigation into your concerns and if necessary lay some traps for confirmation. If it is confirmed that you have cockroaches they will give advice about preparing the room for treatment and request you book a visit for treatment. The cost of this assessment visit £31 is taken from the cost of treatment.
