Cockroach Guide

1. THE DANGERS: WHY WE CONTROL COCKROACHES

DISEASE

Cockroaches present a direct health risk to humans as they act as vectors of disease. They are carriers of organisms responsible for food poisoning, including bacteria such as salmonella, staphylococcus, and streptococcus. Cockroaches commonly move from sewers and drains into buildings and human habitats.

This means that while foraging for food and water within a building, they can contaminate anything they come into contact with, including food, utensils, and preparation surfaces. Adding to the health concerns, cockroaches regurgitate portions of their partially digested food at intervals and leave faeces along their path, contributing to the potential spread of pathogens in the environment.

2. The impact

COCKROACHES AROUND BUSINESSES

The news of a cockroach infestation can swiftly tarnish the reputation of a business. While all businesses are susceptible, those in industries dealing with food and drink, operating within highly regulated environments, face a heightened risk from exposure to cockroaches. If clients and customers observe signs of a cockroach infestation on managed premises, they are likely to complain and may request a refund.

Negative reviews of businesses or products can be easily shared and viewed online, particularly on social media platforms. Apart from the reputational costs, businesses found with a pest problem may incur fines, often at a significant expense, and repeat offenders may face legal action. Environmental Health Officers have the authority to issue enforcement notices to business owners lacking adequate pest management procedures.

If customers observe signs of a cockroach infestation on your premises, they may be hesitant to engage in business with you.

3. PEST FACTS

TYPES OF COCKROACH IN THE UK

Globally, there are approximately 4,600 different species of cockroaches, with a few encountered in the UK. Among them, two of the most common types are the German cockroach and Oriental cockroach. Occasionally, one may also encounter the American cockroach and Brown-banded cockroach.

American cockroaches are the largest among these, measuring around 20-30mm in length. They typically inhabit trees and are not always found in UK homes and businesses. When present, they are usually located in dark, humid, and undisturbed environments like basements.

On the other hand, the Brown-banded cockroach is far smaller, measuring just 10-15mm in length. They prefer warm, humid environments and are commonly found on ceilings, attics, and around appliance motors. Oriental and German cockroaches are more prevalent and likely to be found in UK homes and businesses. When picturing a cockroach in the UK, the image that often comes to mind is usually that of the Oriental cockroach.

4. MANAGING COCKROACHES

PREVENTING COCKROACHES

If you own a business, especially in the food industry, it is advisable to engage a professional pest management company to implement a proactive pest control strategy.

Here are some prevention tips to secure your property:

Keep areas clean and tidy: Thoroughly clean all surfaces to remove any food residue, and regularly sweep up discarded food debris. Avoid leaving dirty dishes and utensils in the sink. Keep bins covered, clean, and emptied regularly.

Clean warm areas: Areas such as the top of or beneath your refrigerator can accumulate food, attracting cockroaches. Clean these areas regularly.

Proofing and repair: Seal gaps around doors, windows, and utility lines to prevent entry.

Repair leaks: If possible, repair any leaks beneath the sink and on the sink top to eliminate potential water sources.

Second-hand items: If you purchase second-hand kitchen utensils like fridges and freezers, thoroughly check and clean them to ensure you haven't unintentionally transported pests.

DIY COCKROACH CONTROL

Contego always recommends you seek professional services when dealing with a cockroach infestation.

However, if you choose to undertake the task yourself, amateur insecticide products are available for purchase. The effectiveness of insecticidal treatments relies on the selection of appropriate insecticides and the thoroughness of the application.

Ensure to pay specific attention to cracks and crevices where eggs and nymphs may be located. The chosen insecticide should ideally have sufficient persistence to eliminate nymphs that hatch later from unhatched egg capsules. When using any insecticide, ensure that it is administered in a safe and secure manner.

Additionally, keep the products out of reach of children and pets to prevent any unintended exposure.

WARNING! When using insecticides, always read the label thoroughly and follow all instructions.
