Easily aid in the conservation of Mason Bees, one of the most highly effective pollinators of flowers, vegetables and fruit crops (they can pollinate 10x more than honey bees!). Hatch house design for solitary Mason or Leafcutter bees. Constructed of durable Cedar, chosen for its weather resistant and insulation properties. Allows filled nesting tubes to be placed in hatch house for emergence and prevents re-nesting in used nest tubes. Use in conjunction with the NEST HOUSE - bees will lay eggs in the nest house, and then filled tubes can be moved over the winter into the HATCH HOUSE for emergence. The larvae will develop over the winter months in the tubes and will emerge as adult bees the following spring. Tubes should be replaced after use or every 1-2 seasons. Mason bees are non-aggressive and cannot excavate their own cavities, so they are not a threat to property. They typically nest in pre-made cavities such as woodpecker holes, insect holes and hollow stems, making the Mason bee house an ideal alternative. Durably constructed of 3/4" cedar, this bee house will provide a lasting habitat with minimal upkeep. SELECTING A SITE: The Mason Bee house can be placed on the ground near the garden, mounted to the side of a building or post, or placed on/near a wood pile. Do not place the house near a bird feeding station. The tube openings should face away from prominent winds. Length: 7.25"Depth: 5.5"Height: 5.0". Made in the USA.
