2024 has been the worst year on record for Britain’s bumblebees.
The Red-tailed bumblebee in particular has been significantly affected this year, more so than any other common bumblebee. This year, their numbers plummeted by 72%.
The cause of this is likely due to the weather. Because of climate change, we’re seeing an increase in weather extremes. This year’s wet spring and cool summer have had a massive impact on bumblebee populations, which are already struggling with habitat loss, fewer flowers, and pesticide use.
Although we can’t control the weather, we can:
- make habitats more resilient to climate change
- influence decision makers to prioritise pollinators, not pesticides
- lead the fight to secure a future for bumblebees
The good news is, you can help
We’re calling on supporters like you to join our fight for bumblebees by making a donation to our urgent appeal.
Together, we can secure a future for bumblebees.
Thank you for your support.

FAQs
Why has it been such a bad year for bumblebees?
Bumblebee queens come out of hibernation in March and April. When queens emerge, they need to establish colonies, and that’s what they’ve struggled with this year.
Queens need to do several things at the same time:
- Find a suitable nest site (usually underground)
- Collect nectar and pollen to feed themselves and their offspring
- Incubate their developing offspring
Colder, wetter weather this summer has impacted all of these points. Underground nests become waterlogged, heavy rain has made foraging for nectar and pollen much harder, and colder temperatures have made it more difficult for queen bumblebees to incubate their offspring (they ‘shiver’ to maintain a nest temperature of around 30°C).
Overall, the weather conditions have made it much more difficult than normal for bumblebees to fly, forage, and nest.
With more queens than normal dying this year, and the ones that do survive unable to nest successfully, this means numbers are much lower than usual. This has a knock-on effect for the following year, with less new queens making it to hibernation.
As well as this year’s harsh weather, bumblebees also have to contend with long-terms impacts too:
Climate change
2024 has been the fourth poor spring in a row, so bumblebees are gradually decreasing, year on year. Climate change means that extreme weather events (such as the 2022 heatwave, or 2023-4 winter flooding) are more frequent and more extreme. This pushes species to the brink of survival.Pesticides
Insecticides can directly kill or affect the ability of bumblebees to find food and reproduce. Herbicides kill the flowering plants which are a vital food source for bumblebees. When bumblebees visit numerous flowers, they can become exposed to a cocktail of different pesticides, which combined can also have lethal effects.Habitat decline
Long-term declines in habitat quality and quantity means that bumblebee populations aren’t as resilient as they used to be because the food availability is poor and there are less places to nest. This means the impact of poor weather years like 2024 is magnified.There have always been poor-weather years, but this one is coming at weakened bumblebee populations, already trying to recover from a series of other extreme weather events.
Why are bumblebees important?
We’ve lost 97% of our wildflower-rich meadows since the 1930s. As the number of flowers in our countryside have declined, so too have our bumblebee pollinators, and they need our help.
84% of all crops in the UK depend on pollination, an estimated service worth approximately £691 million. Bumblebees are responsible for pollinating a wide variety of fruits and vegetables, including tomatoes, peppers, beans, raspberries and strawberries. Without them, many of the foods we eat would become scarce or more expensive.
Bumblebees also pollinate agricultural crops such as oilseed rape, legumes and red-clover, helping to provide forage for the dairy industry. Many farmers rely on bumblebees to ensure high crop yields.
Many flowering plants and wildflowers are also reliant on pollination by bumblebees. This not only provides our gardens, parks and countryside with beautiful colour, but also means these plants can produce the fruits and seeds which feed many birds and mammals, keeping ecosystems balanced and healthy.
Without bumblebees our world would be quieter, less colourful and lack many of the foods we love. Without bumblebees, we could soon face our own crisis.
What can I do to help?
We’re asking people to join our fight to save the bumblebees by making a donation to our charity.
Your donation will support our charity’s work to secure a thriving and sustainable future for bumblebees.
Our actions are driven by the latest bumblebee science, including data from our ‘BeeWalk’ bumblebee-monitoring scheme, and we will work tirelessly to create a world where bumblebees are thriving and valued by everyone.
Together, we can ensure our rarest bumblebees recover and our more common species thrive, so that no more species become endangered in our lifetimes.
