5 Common Pest Controller Problems and When to Call a Professional

The problems that come up most

These are the jobs pest controllers are most commonly booked for. Catching them early almost always costs less:

• scratching in the loft or walls at night
• a wasp nest in the eaves or garden
• droppings in kitchen cupboards
• fleas persisting after shop-bought treatments
• pigeons nesting under solar panels

What you can safely check yourself

Before calling anyone, gather information: when the problem started, whether it's getting worse, and clear photos. This helps a professional give you a realistic first assessment and helps you describe the job accurately when collecting quotes.

Basic observation is always safe; DIY repair is not always. If the problem involves gas, electrics, working at height or the structure of your home, stop at observation and call a professional.

Signs it's time to book someone

Book a professional when the problem is getting worse, when it involves safety, when your own attempts haven't held, or when you simply don't know the cause. A correct diagnosis is usually cheaper than a wrong repair.

For context on cost: A wasp nest treatment typically costs £60–£120. Rodent treatments usually run £120–£250 for a course of visits; squirrel or bird work varies with access and proofing needed.

Choosing who to call

British Pest Control Association members are trained, insured and audited. Technicians using professional-grade rodenticides must hold relevant certification — ask to see it.

Check recent reviews before booking — Hammerscore company pages for pest controllers combine ratings from several platforms, and the low-star reviews tell you most about how problems were handled.
