UK Seasonal Pest Guide - What Pests to Expect Throughout the Year
Every season, when it comes to pests, the UK brings its own challenges. Pests follow specific patterns based on temperature, breeding cycles, and their need for food and shelter. At Dyno-Pest, we track these pest patterns so you can stay one step ahead of potential infestations and protect your property.
When you know what to expect, you can take action before a small problem becomes a major headache. Let’s break down exactly what pests you’re likely to encounter in each season across the UK, and why they choose that particular time to make an appearance.

Spring (March-May)
As you start your spring cleaning, pests are starting their home invasion plans.
- Ants – As temperatures rise, ant colonies wake up hungry and ready to scout your home for food. Those tiny trails leading to your kitchen aren’t a coincidence!
- Wasps – Queens emerge from hibernation to build new nests. If you spot one buzzing around your eaves it’s most likely looking for somewhere to live, and your property is on the list.
- Flies – House flies and cluster flies begin breeding as the weather warms up. One fly today means dozens tomorrow if left unchecked.
- Fleas – These tiny jumping insects become more active as temperatures increase, especially if you have pets bringing them home from spring walks.
- Mosquitoes – Rainy spring days create perfect breeding grounds in standing water. Even a bottle cap of water can become a mosquito nursery!
- Pigeons – Spring is the prime breeding season for pigeons. They’re actively seeking nesting sites on rooftops, ledges, and in roof spaces where they’ll raise several broods throughout the year.
- Seagulls – Peak nesting season occurs in late spring to summer, making gulls particularly aggressive and noisy. They’ll dive-bomb people to protect their young and create significant noise and mess on rooftops and in urban areas.
Summer (June-August)
Summer warmth brings outdoor activities, and heightened pest activity.
- Wasps – Those spring queens have now established colonies that can house thousands. By August, they’re at peak aggression and most likely to crash your garden party.
- Bed Bugs – Summer holidays mean more travel, and these hitchhikers love to return home in your luggage. One souvenir you definitely don’t want!
- Flies – Now in full breeding mode, all types of flies are on the lookout for your food. They’re not just annoying, they can spread serious diseases faster than gossip at a family reunion.
- Ants – Garden and black ants are now fully established and sending scouts far and wide for food sources, like that ice cream your little one dropped.
- Moths – Clothes moths thrive in warm weather, and can turn your favourite jumpers into their meal while you’re storing them for winter.
- Cockroaches – The warm, humid conditions are perfect for these invaders to breed rapidly. One female cockroach can produce up to 300-400 offspring in her lifetime!
Autumn (September-November)
As you pull out your jumpers, pests are looking for their winter hideaways.
- Spiders – House spider season peaks as males search for mates. That’s why you’ll suddenly spot them scurrying across your living room floor!
- Rodents – Mice and rats begin seeking shelter as temperatures drop. Your warm, food-filled home looks like a five-star hotel and attract them into your property.
- Cluster Flies – These flies gather in large groups (hence the name) to overwinter in roof spaces and attics. They don’t bite but can be a real nuisance.
- Cockroaches – Still active from summer, they’re now desperately seeking indoor shelter before winter sets in.
- Beetles – Various beetles, including carpet beetles, move indoors to escape the cold, potentially damaging fabrics and stored foods.
Winter (December-February)
It’s cold outside, which is exactly why pests want to be inside!
- Rodents – Mice and rats are now fully committed to indoor living, gnawing on wires, contaminating food, and generally making a nuisance of themselves.
- Cockroaches – If they’ve found their way in during autumn, they’ll continue breeding throughout winter in heated buildings.
- Bed Bugs – Central heating creates the perfect environment for these pests to thrive, even when it’s freezing outside.
- Moths – Already settled in your wardrobes, they’ll happily eat away on natural fibres throughout the winter months.
- Stored Product Insects – Beetles and weevils infesting dry foods often go unnoticed until winter, when you’re using those longer-term pantry supplies.
Year-Round Unwelcome Pests
Some pests don’t follow the seasonal rulebook and can cause problems any time:
- Pharaoh Ants – These tiny indoor specialists breed continuously in heated buildings.
- German Cockroaches – In commercial kitchens and blocks of flats, these pests breed year-round in warm conditions.
- Bed Bugs – Once established, they don’t care what season it is as long as there’s blood to feed on and warm places to live.
- Pigeons – While breeding peaks in spring and summer, pigeons can breed year-round in urban environments where food and shelter are consistently available, creating ongoing issues with droppings, noise, and potential disease spread.
- Seagulls – Though nesting is seasonal, gulls remain present in coastal and urban areas throughout the year, causing noise disturbance, fouling, and sometimes aggression toward people.
Don't Wait for Pests to Make Themselves at Home
Remember, prevention is always better than cure. By the time you spot one pest, there are likely dozens more hiding away. Our professional team at Dyno-Pest can help you stay pest-free all year round with targeted treatments that tackle seasonal invaders before they become a full-blown infestation.
