Small Gaps, Big Pest Problems: Why Pest Proofing Matters for Commercial Buildings

Many businesses only think about pest control once there’s a visible problem - a mouse sighting, droppings, flies, or complaints.

But the truth is:by the time you see pests, they’ve often been present for a while.

That’s why pest proofing is one of the smartest preventative services a commercial site can invest in.

At Denma Cleaning Services, we provide pest control and proofing across Eastbourne, Portsmouth, Bristol, Bolton, Birmingham, Manchester, and Sheffield, helping businesses stop pests at the source.

Pests Don’t Need a Big Opening

A common misconception is that rodents need large holes to enter.

In reality:

• Mice can squeeze through gaps as small as 6mm

• Rats can enter through gaps around 20mm

That means the smallest building weakness can become a major risk.

The Most Common Pest Entry Points We Find

Here are the most common weak spots we regularly identify during commercial site checks:

1. Gaps Around Pipework

Pipes that run through walls often leave gaps that are never sealed properly.

2. Damaged Door Seals

External doors with worn seals are one of the biggest causes of repeat pest issues.

3. Poorly Fitted Roller Shutters

Warehouses and loading bays are particularly vulnerable.

4. Broken Vents, Air Bricks, and Grilles

These are often overlooked - and pests love them.

Why Pests Are a Serious Business Risk

Even one pest incident can lead to:

• hygiene and contamination risks

• staff anxiety and complaints

• damaged stock or property

• failed inspections

• reputational damage

For businesses such as:

• offices

• warehouses

• engineering facilities

• shops

• dental clinics

• food environments

…pest prevention isn’t optional - it’s essential.

Pest Control vs Pest Proofing

This is where many companies go wrong.

Pest control means:

• baiting

• trapping

• monitoring

Pest proofing means:

• sealing entry points

• installing guards and barriers

• improving waste storage advice

• preventing access permanently

The best results come from doing both.
