February 17 2022 – Harrison Broadhurst

Putting up a bat house is one of the best ways you can help save the bats and also sustainably reduce pest insects from your yard. But there are many different types of bat houses: single-chambers, muli-chambers, and even giant bat houses… How do you know what type of bat house to install? 

You’ve come to the right place! 

In this article, we’ll guide you through a few different types of bat houses to help you decide which is ideal for your property and situation.

BAT-FRIENDLY DESIGN

Before installing a bat house, the first thing you should check is that the design is bat-expert approved. Bat expert Dr. Merlin Tuttle reports that close to two-thirds of bat houses on the market are poorly designed and constructed, or are sold with inadequate instructions, making them unlikely to succeed. Make sure your bat house has the following features to help ensure an ideal sanctuary for the bats:

  • TALL CHAMBERS

  • STRONG GRIP

  • PROPER VENTILATION

  • PROTECTION AND SEALANT

  • HIGH QUALITY LUMBER AND BUILD

Note: The placement of your bat house has a strong influence on its success. See our hanging guide that has tips to help you choose the best location for your bat box.

 

BAT HOUSE TYPES

Now moving on to the types of bat houses:

BatBnB currently has three different types of bat houses: 

Let’s dive into their differences and which situation is ideal for each.


SINGLE-CHAMBERED:

Single-Chamber Bat House

Single-Chamber Bat House

SPECS:

  • Dimensions: 4x18x34’’ (LxWxH)

  • Occupancy: The smallest bat house, fitting up to 50 bats. 

  • Vents: One long frontal vents

USE WHEN:

  • Ideal for testing bat needs in a new area where bat houses haven’t previously been used. Bat expert Dr. Merlin Tuttle recommends trying two: placing one so that it is more exposed to the sun than the other. Using this initial approach can double the odds of success. Bats like options!

WHERE TO USE:

  • The ideal placement for single-chamber bat houses is on walls of buildings which can help stabilize temperature in these less thermally stable designs. In moderate climates they also can  be used on poles.

WHERE TO PLACE:

  • Either on a wall or a pole

Other than these factors, aesthetics is the other main difference. You can choose the style you prefer for your home and garden.
