Ivy Mining Bees
If you notice lots of small bees flying close to the ground, nesting in lawns, flowerbeds or soil banks, please don’t panic. They may be ivy mining bees (Colletes hederae).
Despite sometimes appearing in large numbers, these are solitary bees, not a dangerous colony. Each female creates her own small nesting tunnel, although many may nest close together where the soil conditions are suitable.
Ivy mining bees are:
✅ Gentle and non-aggressive
✅ Unlikely to sting, even around their nesting areas
✅ Harmless to people, pets and buildings
✅ Important pollinators, particularly of flowering ivy
✅ Seasonal visitors that disappear naturally
Pesticide treatment is unnecessary and should be avoided. The best course of action is simply to leave them alone and enjoy watching these valuable native pollinators.
Please share and help protect our harmless mining bees.
