Ladybirds Take Over Windows and Walls – UKNIP

Swarm Alert! Ladybirds are invading homes across the UK as they hunt for winter warmth. This surge is linked to the recent warm spell and the creepy crawlies’ natural instincts to settle in before the cold kicks in.

Ladybirds Take Over Windows and Walls

People nationwide have spotted clusters of ladybirds gathering on windows, walls, and door frames. Some unlucky homeowners have even found them inside their houses and garden sheds.

Why the Sudden Surge?

Entomologists say the boom in ladybird numbers is thanks to a spike in aphids this summer, giving them plenty of grub. Now, with dropping temperatures, these beetles are scrambling to find cosy spots to hibernate.

Harlequin Ladybirds Are Leading the Charge

Most sightings are of harlequin ladybirds – an invasive species that prefers sneaking indoors for warmth rather than hiding in trees or leaf litter like native bugs.

No Need to Panic – But Be Gentle

Experts assure us these ladybirds are harmless, although they might leave small yellow stains or bite if provoked. Homeowners are urged to carefully release any indoor ladybirds back outside to join the winter hibernation frenzy.
