Pest Control Experts Warn of Overwintering Insects Invading UK Homes

Pest Control Expert Issues Warning as ‘Overwintering’ Insects Set to Invade UK Homes

As temperatures drop across the UK, homeowners may soon find themselves facing an unexpected invasion—not from rodents or traditional household pests, but from overwintering insects seeking shelter indoors. According to pest control experts, a surge in insect activity is expected as bugs look for warm, dry places to survive the colder months.

What Are Overwintering Insects?

Overwintering insects are species that enter a dormant-like state during winter, seeking refuge inside homes, attics, and other warm environments to escape the cold. While these insects don’t actively breed or cause structural damage during this period, their sheer numbers and presence can become a nuisance for homeowners.

Common overwintering insects in the UK include:

• Cluster flies – Often found in attics and window frames.
• Ladybirds (Harlequin ladybirds) – Harmless but can invade in large numbers.
• Stink bugs – Emit an unpleasant odor when disturbed.
• Boxelder bugs – Typically found on warm exterior walls before moving indoors.

Expert Warning: A Surge in Home Invasions

Pest control specialists are warning that milder autumn temperatures followed by sudden cold snaps could lead to an increased presence of these insects in UK homes. As outdoor temperatures fluctuate, bugs are more likely to seek stable environments—often leading them inside through cracks, vents, and windows.

A spokesperson from a leading pest control company stated:
“We are already seeing a rise in calls from homeowners dealing with overwintering insect invasions. Many of these pests enter homes unnoticed and settle in hidden spaces like lofts, basements, and wall cavities. While they aren’t dangerous, they can be difficult to remove once established.”

How to Prevent Overwintering Insects from Invading Your Home

Experts recommend taking preventative measures now to avoid dealing with an infestation later. Here are some tips to keep overwintering insects at bay:

1. Seal Entry Points – Check for cracks around windows, doors, and vents. Use caulk or weather stripping to block small gaps.
2. Reduce Indoor Attractants – Bugs are drawn to warmth and moisture. Keep your home dry, and use dehumidifiers in damp areas.
3. Inspect Attics and Basements – Overwintering insects often hide in undisturbed areas. Regularly check and clean these spaces.
4. Use Screens and Seals – Install mesh screens on vents and chimneys to prevent bugs from entering.
5. Call a Pest Control Expert – If you notice a large number of insects inside, professional pest control services can help safely remove them.

What to Do If You Already Have an Infestation?

If overwintering insects have already entered your home, it’s essential to act quickly:

• Avoid crushing bugs like stink bugs, as they can release foul odors. Instead, gently remove them with a vacuum and dispose of them outside.
• Use insect traps in areas where bugs are congregating.
• Consult a professional if the infestation becomes overwhelming.

Conclusion

With the winter season approaching, UK homeowners should be prepared for an increase in overwintering insect activity. By taking proactive measures now, you can prevent these unwanted guests from settling into your home. If you suspect an infestation, acting quickly can make all the difference in keeping your living space pest-free.
