Cockroach Infestations


It must surely be the most detested and hated of insects, and with good reason. It infests a property in numbers, can be incredibly difficult to get rid of and can spread diseases, as well as cause other issues, one of which is allergies.

Not many people are aware but the cockroach can cause allergic reactions in some people. Those who are asthmatic, or sensitive to the house dust mite can find that on exposure to a cockroach infested property or area, they can feel unwell. However, it is probably true to say that anyone who spends more than a few minutes in a cockroach infested house or building will soon feel distressed and anxious.

The species

In the UK, the most commonly dealt with cockroach species are the German cockroach and the Oriental cockroach. Adaptable and mobile, the cockroach can make its way into a new building via sewers, pipes, ducts and so on. The hole only needs to be the smallest crevice, almost unseen by the human eye.
The Oriental cockroach can be identified as it is the bigger of the two species found in the UK, and it is the most common too. Congregating in water sources, this cockroach can also climb rough walls, such as brickwork. The German cockroach on the other hand, can easily scale a smooth plastered wall.

Not sure if there is an infestation?

Although they can and do infest in large numbers, neither species of cockroach enjoy or seek out human company. Hence, as soon as walk in to a room, they scuttle and hide in the corners, behind units and so on. They are mainly nocturnal creatures hence they can be present in a property without the homeowner knowing for a long time.
There may be some tell-tale signs but using a sticky trap can be one way of determining if you have cockroaches or not. Lay it at night in the kitchen or wherever you think the cockroaches are, and check back in the morning…


As with all pests, prevention is better than cure and when it comes to high danger areas – food serving and preparation outlets, hotel kitchen, take-aways and so on – hygiene needs to be top of the list.
This does not mean only the interior of a property but the exterior too. Food waste should be tightly sealed bags, and then disposed of in tightly sealed bins that should be emptied on a weekly basis, more often if the refuse is liable to spill over in a matter of days.
When an infestation does strike, it needs to be dealt with. It will not go away of its own accord, but if left untreated will simply gather pace. Baiting, gelling and use on insecticides is common in this kind of infestation, followed by cleaning and the application of heat too, in some cases. 


However, there is sometimes need in some situations to proof an area against cockroaches and this investment can pay dividends in high risk areas.
Cockroaches are nocturnal, preferring dark, warm spaces – the kitchen or bathroom is perfect – and cracks in floors, walls and ceilings make perfect access points. These small cracks and crevices need to be filled and, as far as is possible, any voids in walls cavities filled too.

Eradication and the law

For food premises, it is a legal requirement that cockroaches are dealt with in a timely way. In other words, all food premises are expected to act in a way that discourages all pests but, in the case of cockroaches this means ensuring that their premises and habits do not allow cockroaches to take hold.
When a food premises suspects an infestation, by law they must act and the best and safest route to dealing with a cockroach issue is to call in professional pest controllers.

In summary

More and more people are aware of the dangers that some pests can pose to their health – the cockroach being one of them – but are also now increasingly mindful of the types of chemicals that were once accepted as part of treatment.
Cockroaches have become resistant to some chemicals too and thus, simply laying down any poison or gel is no longer effective. The safest option for both human health and the environment is the treatments offered by a professional pest control company or technician.
