Build a Bat House: Free Plans and Instructions

Bat houses provide a safe and sheltered habitat for bats, which are beneficial insects that control mosquito populations and other pests. While there are many pre-made bat houses available for purchase, building your own can be a rewarding and cost-effective project. This article provides free plans and step-by-step instructions for building a bat house, allowing you to create a welcoming haven for these essential creatures.

Understanding Bat House Design

The success of a bat house hinges on its design. Bats have specific nesting preferences, and a poorly-designed house can deter them from taking up residence. Here are some key design features to consider:

Location:

Select a location that receives at least six hours of direct sunlight daily. Ensure adequate drainage to prevent water from pooling inside the house. The house should be mounted at least 10-15 feet above ground, away from potential predators and human activity. A south-facing wall is ideal for optimal warmth.

Size and Dimensions:

The optimal size for a bat house is determined by the species of bats you aim to attract. Smaller bats, like the little brown bat, prefer smaller houses. Larger bats, such as the big brown bat, need larger structures. Consult local bat conservation organizations or online resources for species-specific dimensions.

Materials:

Bat houses are typically made of wood. Cedar, pine, and redwood are popular choices due to their durability and natural pest-resistant qualities. Avoid using treated lumber, as it can be harmful to bats.

Entrance:

The entrance should be a narrow slot, typically 1-2 inches wide, positioned at the bottom of the house. This design prevents predators from entering and facilitates natural air circulation. The entrance should face south or east for optimal warmth and sunlight.

Interior:

The interior should be rough and unfinished, providing a suitable surface for bats to cling to. Avoid painting or varnishing the interior, as these coatings can harm bats.
