Why do I have cockroaches?
Cockroaches can be brought into a building on a product - foodstuffs and spices are a very common route. Cockroaches can also travel through from a neighbouring building or from another part of your building if you live in an apartment block or housing complex.

They are attracted to warm, humid climates which is why they are so often found in kitchens. An infestation can be avoided by having good ventilation and ensuring that all surfaces, floors and equipment are regularly cleaned thoroughly. By blocking up potential breeding spots like holes in the wall, you also bolster your chances of preventing an infestation.


What kind of cockroaches do I have?
The two main species of cockroach predominantly found within the UK are the German Cockroach (Blattella germanica) and the Oriental Cockroach (Blatta orientalis). 

The German Cockroach is probably the most common in the UK (shown in image above). Typically 12-15mm in length and easily identifiable by its light to mid-brown colour and the two dark stripes which run down its thorax. The German Cockroach reproduces at an alarming rate with just one female producing up to 320 offspring! Favouring heated buildings with high humidity, the German Cockroach is a pest frequently found in the kitchens of restaurants, takeaways and hotels and is also sometimes found in dry cleaning businesses.

The Oriental Cockroach (see image to right) is less common.oriental cockroach It measures 25-30mm in length and is dark brown to black in colour. Oriental cockroaches are still rapid breeders, with one female producing up to 160 offspring. Although oriental cockroaches will live in buildings, they are more frequently found outdoors, favouring rubbish tips and even sewers. The Oriental cockroach is much more mobile as it has the ability to take flight, unlike the German cockroach, even though it does have wings.


What is the best and most effective cockroach treatment?
Firstly, identifying the type of cockroach infestation that you have is not important, as the treatment process and cockroach killer products which you use will be the same regardless of species.

Our Cockroach Killer Kits provide the best solution for eradicating a cockroach infestation in a domestic home or commercial kitchen. If you've never carried out a cockroach treatment before do not worry, as full detailed step-by-step instructions are included. Available in 3 different pack sizes, each Kit contains all the key cockroach control products from Pest Expert / Rentokil including: Pest Expert Formula 'C' Cockroach Killer Spray with its long-lasting insecticide residual, Formula 'P' Cockroach Powder and Cockroach Traps.

Also available below is Pest Expert Formula IC Cockroach Gel for use. This excellent professional-use product is frequently used in restaurant and other commercial kitchens where cockroach spays have a shorter residual life due to frequent cleaning.
