Cockroaches are a high risk pest to have in the home.
They carry a range of serious illnesses including salmonella, dysentery, gastroenteritis and typhoid.
The risk is particularly high in homes with children, the elderly or those fighting illnesses.
Cockroach droppings also cause eczema and asthma.
Beyond the health risks, cockroaches are a distasteful pest to have in the home. Not only are they disturbing by sight, but cockroaches produce an obnoxious odour that taints food and objects they come into contact with.
Cockroaches can breed rapidly and are highly resilient. A quick response is essential to ensure a cockroach infestation does not become established or spread to neighbouring properties.
There are three common species found in the home:



Both species will tend to be found in greatest numbers in the kitchen or where food is stored.
Sealing entry points can help prevent a cockroach from entering the home. Key risks are gaps under doors or around pipes to the exterior, or neighbouring properties.
Also seal gaps where cockroaches can harbour - cockroaches are nocturnal and hide during the day in cracks and crevices in the walls, around skirting boards or behind electrical sockets.
The most effective way of controlling cockroaches is to deny them food and water:
In our view, electromagnetic or ultrasonic repellers do not work with cockroaches and are not recommended to prevent or control cockroach infestations.
If untreated, cockroaches quickly establish themselves in high numbers and will spread to adjoining properties.
Rentokil offers a range of DIY products that kill insects including cockroaches but an established cockroach problem will often require professional pest control to ensure that it will not reoccur.
Rentokil offers a range of DIY insect killers that are effective on cockroaches. Please follow the instructions to ensure safe and effective use.
However, it is difficult to reach all cockroach hiding places with amateur products. Infestations are likely to reoccur especially when surviving cockroach eggs hatch after one or two months.
Cockroaches are very resilient and while Rentokil DIY products can deal with the immediate problem, treatment by a qualified pest control technician is often necessary to deal with cockroaches over the long-term.
Rentokil technicians have a range of powerful insecticides to deal with cockroaches.
We also minimise the risk of insecticides in the home with proprietary products such as non-toxic RID (Rentokil Insecticide Dust) or PyGo which is highly targeted at the crevices where cockroaches hide.
