How to get rid of cockroaches

There are a number of options available for exterminating cockroaches. When applied correctly, each can control cockroaches effectively. Professional treatment is the most effective way to get rid of cockroaches in your home or business to guarantee a long-term solution and prevent re-infestation.

For businesses, a cockroach infestation will result in contamination of food and surfaces, damage to stored food, potential action by food safety authorities and damage to your reputation. The health hazards associated with this disease-spreading insect are a concern for both homeowners and businesses.

Below is a description of the treatments available for getting rid of cockroaches.

Cockroach bait

Cockroach bait is one of the most common methods of cockroach control and is extremely effective in indoor locations such as kitchens (both commercial and residential), food handling and preparation areas, hotels and hospitals.

Cockroach baits come in three formats:

  • Liquid
  • Gel
  • Solid

The success of the treatment exploits the cannibalistic nature of cockroaches to help successfully remove an infestation. The bait is placed in strategic areas around a property where cockroaches are known to dwell. The toxins in the bait will not only affect the cockroach that consumes the bait, but also affects other roaches through secondary transmission.

After a cockroach has fed they will often return to the nest where they will defecate. Any other cockroach which consumes the faeces, saliva, or carcass of the infected roach will also be affected by the cockroach bait. Infection can also occur through direct contact with the toxins from the bait dispersed within the cockroach nest.

Essentially this creates a cycle of cockroaches becoming infected and passing it on to other roaches. Because of this, cockroach bait has a proven track record of successfully exterminating whole colonies of cockroaches.

Cockroach fumigation

Fumigation is the more traditional method of cockroach control. This involves the use of insecticides in a gas to exterminate the cockroaches in a confined space.

The fumigation process involves sealing a facility, or part of a facility, where a cockroach infestation is at a high level. A gas is then introduced into the area to reduce the population. Fumigation generally is applied as an addition to other cockroach control services when the infestation is at a high level.

Cockroach fumigation is highly effective for businesses such as:

  • Manufacturing
  • Warehousing
  • Agriculture
  • Milling

There are a number of fumigation techniques, with each one being tailored to the environment it is used in.

Heat treatment

Heat treatment is an environmentally friendly chemical-free option for getting rid of cockroaches in certain situations. This method eradicates cockroaches at every stage of their life cycle from egg to adult.

Entotherm heat treatment

Rentokil’s Entotherm heat treatment is a pesticide-free solution. It consists of a mobile system that delivers dry heat in a portable container between 50°C and 60°C for a monitored period. This ensures the cockroaches are killed without causing any damage to your property.

The Entotherm heat treatment is suitable for businesses such as hotels, schools, hospitals and restaurants.

Proactive cockroach control

Proactive cockroach control is best suited for businesses, especially those handling food where it can help to comply with food safety legislation, standards and audit requirements for food hygiene.

It involves taking active measures to prevent infestation and monitor for early signs of an infestation.

Cockroach prevention

Following cockroach prevention best practices is the most efficient way of proactively controlling cockroaches.
