Living in Cornwall is a dream for many. The stunning coastline, charming villages, and lush countryside make it a wonderful place to call home or run a business. But, like anywhere else, Cornwall has its share of pesky visitors - pests! Whether you’re dealing with ants in the kitchen, mice in the attic, or wasps buzzing around your garden, pests can quickly become a headache. Don’t worry - I’m here to help you understand the common pest issues Cornwall faces and how to tackle them effectively.
Understanding Common Pest Issues in Cornwall
Cornwall’s mild climate and diverse habitats create a perfect environment for a variety of pests. Some are more common than others, and knowing what you might encounter is the first step to keeping your property pest-free.
Ants and Their Sneaky Invasions
Ants are one of the most frequent nuisances, especially during warmer months. They love to invade kitchens in search of crumbs and sugary spills. While most ants are harmless, their presence can be irritating and unsightly.
How to spot them? Look for tiny trails of ants marching in a line, often near food sources or damp areas. They can enter through the smallest cracks, so sealing entry points is crucial.
Mice and Rats - The Unwanted House Guests
Rodents are a serious concern. They can cause damage by chewing wires, insulation, and even wooden structures. Plus, they carry diseases that can affect your health.
Signs of rodents include droppings, gnaw marks, and scratching noises at night. They often seek shelter indoors during colder months, making winter a critical time for prevention.
Wasps and Bees - Garden Visitors or Threats?
Wasps can be aggressive, especially if their nests are disturbed. They tend to build nests in eaves, sheds, or underground. Bees, on the other hand, are vital pollinators and protected by law, so it’s important to handle them with care.
If you notice a wasp nest near your home, it’s best to act quickly but safely. Avoid DIY removal unless you’re experienced, as wasps can sting multiple times.
Other Common Pests: Fleas, Spiders, and Woodworm
Fleas often hitch a ride on pets and can quickly infest your home.
Spiders are mostly harmless but can be unsettling for some.
Woodworm larvae can damage wooden furniture and structures, leading to costly repairs.

Practical Tips to Prevent and Manage Pest Problems
Prevention is always better than cure. Here are some practical steps you can take to keep pests at bay:
Keep It Clean and Dry
Pests love food crumbs, spills, and damp areas. Regularly clean your kitchen, vacuum floors, and wipe down surfaces. Fix any leaks or damp patches promptly.
Seal Entry Points
Inspect your home for cracks, gaps, and holes. Use weatherproof sealant or mesh to block these entryways. Don’t forget to check around windows, doors, and where pipes enter the building.
Manage Waste Properly
Store rubbish in sealed bins and dispose of it regularly. Compost heaps should be kept away from the house and turned often to avoid attracting pests.
Maintain Your Garden
Trim bushes and trees away from your home. Remove debris and standing water where pests can breed. Keep firewood stacked away from the house and off the ground.
Use Natural Deterrents
Certain plants like mint, lavender, and marigold can repel insects. You can also use essential oils or vinegar sprays as natural deterrents.
