Butterfly & bee houses

Nesting blocks for native solitary bees and shelters for the garden's quieter visitors.

Roughly 30% of North America's 4,000 native bee species nest in hollow stems and beetle tunnels. A good nesting block mimics those — smooth, dry and the right diameter.

Hang bee blocks facing east or southeast by early spring. Butterflies need host plants (milkweed, asters, spicebush) far more than they need a house.
