When it comes to dealing with pests in London—whether it's rodents, cockroaches, or bedbugs—many homeowners and businesses rush to call in professional help. And while that’s the right first step, not every pest control service delivers the same quality of work.

Hiring the wrong team can lead to wasted time, money, and even recurring infestations.

To help you make smarter choices, let’s explore the top mistakes people make when hiring pest control services in London—and how to avoid them.

1. Not Checking for Proper Licensing and Certification

One of the most common and dangerous mistakes is hiring a pest control company without verifying their licenses and certifications. Pest control involves the use of chemicals and procedures that must comply with health and safety standards.

Without proper accreditation, the service may be using outdated or even harmful methods, putting your family, pets, or customers at risk.

Tip: Always ask if the company is certified and trained according to UK pest control regulations before allowing them on your property.

2. Choosing Based on Price Alone

It’s natural to look for a good deal, but when it comes to pest control, the cheapest option is rarely the best.

Many people make the mistake of hiring the lowest-priced service without understanding what’s included—or not included—in that quote. Some companies cut corners, skip crucial steps, or use ineffective treatments to lower their prices.

The result? The pests come back, and you end up spending more in the long run.

Tip: Focus on value, not just cost. Ask what’s included in the treatment plan, and ensure it covers both short-term removal and long-term prevention.

3. Failing to Ask About the Treatment Process

Not all pest problems are treated the same way. Yet, many people don’t ask what methods the pest control team will use.

Some companies might use generic solutions that aren’t suited to your specific pest issue, or they may not explain how many visits are needed. If you’re not clear on the treatment plan, you’re likely to be left confused—and still dealing with pests.

Tip: Ask for a step-by-step explanation of how the treatment will be carried out, including how long it will take, what products will be used, and if follow-up visits are needed.

4. Ignoring Reviews and References

Word of mouth matters. Another major mistake is not checking online reviews or asking for references before hiring a pest control company.

Past customers often share insights into the company’s reliability, professionalism, and results. Skipping this step could mean hiring someone with a bad track record.

Tip: Take time to check Google reviews, testimonials, or even social media feedback to get a real sense of the company’s performance.

5. Overlooking Guarantees or Warranties

A reliable pest control service should stand behind its work. But many people forget to ask whether a guarantee or warranty is offered on the service.

If the pests return within a few weeks, will they come back and treat it again? Or will you be charged all over again?

Tip: Choose a company that offers clear guarantees, so you're protected in case the treatment doesn’t fully work the first time.

6. Not Asking About Preventative Advice

Getting rid of pests is only part of the job. Keeping them from coming back is just as important.

Many homeowners make the mistake of not asking for prevention tips or guidance. A good pest control provider should help you identify entry points, food sources, or sanitation issues that may be attracting pests.

Tip: After the treatment, ask what changes you can make around your home or business to prevent future infestations.

7. Hiring Without a Home or Site Inspection

No two pest infestations are exactly alike. Yet, some people hire pest control services over the phone—without even having an inspection first.

This can lead to poor diagnosis, wrong treatment plans, or surprise charges later on.

Tip: Look for a company that offers a proper assessment of your property before recommending a solution. This shows professionalism and ensures you get the right treatment for your situation.
