Biting Midges on the Rise: Climate's Role in a Buzzy Summer in Lower Saxony
A multitude of mosquitoes reside in Lower Saxony, Germany - A substantial increase in mosquito population predicted for Lower Saxony
Get ready to batten down the hatches, folks, 'cause those pesky biting midges are back, and this time they're out in full force! The local health department predicts a bumper crop of biting midges for this season, and it seems our warming climate is to blame.
The mild winter we've had? Yep, that's just what these insidious critters need to flourish. According to our sources, mild winters make it easier for midges to survive, while summer downpours provide them ample breeding grounds in puddles and bodies of water.
Common house midges (Culex pipiens) seem to be the most prolific this time around, but there's another unwelcome guest on the horizon: the tiger midge, an exotic species that's been making its way up north. The warmer summers and changing rain patterns have created a welcome mat for these unwanted intruders.
Sure, a few bites here and there might just be a nuisance, but beware: these critters can carry some nasty stuff. The West Nile virus, for instance, has been cropping up in Germany since 2018, and it's caused quite a stir in both humans and animals alike. Last year, the virus was detected in Lower Saxony for the first time ever, infecting three humans and several horses.
Don't panic just yet, though! There are steps you can take to protect yourself. Wearing long clothing and using midge repellants is a good start. Additionally, if you've got a garden, keep an eye out for potential breeding grounds like watering cans and uncovered rain barrels, and cover them up to prevent a midge party.
Now, as for those exotic tiger midges, it's still early days, but they're theoretically capable of transmitting tropical diseases like dengue, Zika, and Chikungunya. Thankfully, none of these pathogens have been found in German tiger midge populations, but it's better to be safe than sorry. Keep an eye out for tiger midge populations so we can nip them in the bud before they become a bigger problem.
There's no vaccine available for humans just yet, but fear not: our four-legged friends have a shot at protection against the West Nile virus. Vaccines are recommended for horses living in affected areas, so consult with your vet if you're concerned about your horse's health.
With climate change on the rise, it seems these midges are here to stay. Let's all do our part to keep them at bay and stay healthy this summer!

Climate Change and the Rise of Midges: Increased Populations and Activity
Warmer, wetter conditions due to climate change create more favorable environments for biting midges (Culicoides spp.) to thrive. These conditions can extend their active season and increase their reproductive cycles, leading to higher population densities in regions like Lower Saxony, Germany.
Warmer temperatures may also allow exotic species such as the tiger midge to establish and expand their range northward, including Lower Saxony. Exotic midges could introduce new disease pathogens or compete with native species, altering local ecosystems.
To protect yourself, consider wearing long clothing, using midge repellent, and keeping an eye out for potential breeding grounds like standing water or uncovered containers. Vaccines for horses are available to protect against the West Nile virus, which has been detected in Lower Saxony and can cause severe symptoms in both animals and humans.
Climate Change Impact on Biting Midges in Lower Saxony, Germany
Population Changes
- Rising temperatures and milder winters provide more suitable conditions for biting midge survival and reproduction, potentially leading to increased population densities.
- Warmer and wetter conditions may create more suitable breeding habitats for midges, such as wet soil, marshes, and stagnant water bodies.
Activity and Distribution
- Increased temperatures may extend the activity periods of midges, with species potentially being active earlier in spring and later into the autumn months.
- Warmer, wetter conditions can facilitate the spread of exotic midge species, allowing them to establish and expand their range northward.
Ecological and Economic Consequences
- Higher midge populations and prolonged activity may lead to increased biting pressure on humans, livestock, and wildlife, causing discomfort and economic losses in agriculture.
- Exotic midges could introduce new pathogens or compete with native species, altering local ecosystems.
The rise of biting midges in Lower Saxony highlights the connection between climate change and invasive species, and the potential impacts on human health and local ecosystems. Monitoring efforts and midge control strategies are essential for maintaining public health and mitigating economic losses.
- The increased activity and densities of biting midges (Culicoides spp.) in Lower Saxony, Germany, can be attributed to warmer, wetter conditions that result from climate change, which in turn create more favorable environments for these pests.
- Exotic midge species, such as the tiger midge, may establish and expand their range due to these favorable conditions, introducing new disease pathogens or altering local ecosystems.
- To minimize the impacts of biting midges on human health and economic losses, it is crucial to implement prevention measures such as wearing long clothing, using midge repellent, and monitoring potential breeding grounds. Vaccines for horses are also available to protect against the West Nile virus, a disease detected in Lower Saxony and potentially transmitted by these pests.
