Summer is over. The sandals are away, the evenings are darker and the heating might already be making an appearance.
Surely that means insect repellent can go back in the cupboard until next summer?
Not necessarily.
While insect activity generally changes as temperatures fall, autumn doesn’t mark an instant end to biting insects in the UK. Mosquitoes, midges and ticks don’t work to the summer calendar — and some can still be active well into autumn.
So, if you’ve found yourself asking “What is still biting me in October?”, you’re not imagining it.
Here’s what could still be out there.
Are mosquitoes still around in autumn in the UK?
Yes.
The UK has numerous native mosquito species, and their active seasons vary considerably.
According to the UK Health Security Agency (UKHSA), some British mosquitoes remain active into October. Aedes punctor, for example, can be active until October, while Aedes caspius can remain active until late October and Aedes detritus from March through to November.
Then there’s Culiseta annulata — one of the most common mosquitoes in the British Isles and an especially relevant one as the seasons change.
Unlike most British mosquitoes, it can remain active throughout the year. UKHSA notes that reports of mosquito biting during late autumn and early spring can almost always be attributed to this species.
In other words: October does not automatically mean the end of mosquito season.
Temperature, rainfall, habitat and the particular mosquito species all play a part in how long activity continues.
Why am I seeing mosquitoes inside my house in autumn?
There’s another reason you may suddenly notice insects when the weather turns colder: some are heading indoors too.
UKHSA notes that female common house mosquitoes (Culex pipiens) begin entering homes, garages and sheds during autumn to overwinter as temperatures fall.
That doesn’t necessarily mean every mosquito you see indoors is looking for its next meal. But it does explain why closing the door on summer doesn’t always mean closing the door on mosquitoes.
Autumn has arrived. Some of the bugs have simply come with us.
Are midges still biting in autumn?
They can be.
Biting-midge activity is heavily influenced by weather conditions, including temperature, wind and rain. Government guidance relating to biting midges describes April to November as their main period of activity in Great Britain.
For anyone spending autumn walking, camping or enjoying the countryside — particularly around damp, sheltered environments — that makes insect awareness worth keeping on the agenda a little longer.
Crisp autumn walk? Absolutely.
Becoming someone’s dinner? Less appealing.
What about ticks in autumn?
Ticks are another reason not to think of bite prevention as exclusively a summer concern.
Although tick activity is generally higher during the warmer months, ticks can be present throughout the year in the UK. They are commonly associated with grassy and wooded environments.
That makes autumn walks through woodland, countryside and long vegetation a good time to remain tick-aware.
Wear appropriate clothing, stick to clear paths where possible and check yourself — as well as children and pets — after spending time in areas where ticks may be present.
If you find an attached tick, follow NHS guidance for safe removal.
So, do I need insect repellent in October?
It depends on where you are, what you’re doing and the conditions.
You probably don’t need to approach a chilly October day in the same way you would a warm July evening.
But insect repellent can still be useful to keep close if you’re:
- Spending time outdoors during mild autumn weather
- Walking or staying near woodland, wetlands or water
- Camping or enjoying a countryside break
- Experiencing mosquitoes or biting insects around your home
- Heading somewhere warmer for an autumn holiday
- Simply someone the bugs seem to find before anyone else
Because insect season doesn’t end neatly when summer does.
And then there’s autumn travel…
While Britain cools down, plenty of us are heading in the opposite direction.
October half-term escapes. European city breaks. Winter sun. Long-haul holidays.
Your local weather at home tells you very little about the insect activity at your destination, so check current travel-health guidance for wherever you’re going before you leave.
And yes — insect repellent may still deserve a place in the wash bag.
Preferably before you arrive and discover you needed it.
