That decorative bee hotel from the garden center might actually be hurting the bees.
Scott MacIvor, a researcher at the University of Toronto, set up 200 bee hotels across Toronto and monitored them for three years.
What moved in: parasitic wasps, spiders, earwigs, ants, and in one case a mouse. Not villains, but also not bees.
Native bees did use them, but the large clustered design made it easy for disease and parasites to spread between nests in a way that would never happen in nature, where nesting sites are scattered and isolated.
Here's what most commercial bee hotels get wrong:
Plastic tubes trap moisture and grow mold. Bamboo tubes are usually too large for most native bee species.
Pine cones, bark, and moss, seen in virtually every decorative hotel, aren't used by bees and attract the wrong insects.
Holes too short produce almost exclusively male offspring, skewing the population. No maintenance plan means disease and parasites accumulate year over year with no way to clean them out.
The bigger problem: 70% of North American bee species nest in the ground. A bee hotel does nothing for them.
What actually works:
🌿 Leave bare patches of undisturbed soil in a sunny spot
🪵 Leave dead wood and hollow stems standing
🌸 Plant native flowers that bloom in sequence spring through fall
đźš« Stop using pesticides
The bees don't need a hotel. They need a habitat.
