Chosen theme: Making Bat Houses for Nighttime Pollinators. Join us as we blend craft, conservation, and wonder to welcome nocturnal pollinators into our backyards, boost local biodiversity, and spark community curiosity after sunset.
While many bats eat insects, pollinating species visit night-blooming flowers, spreading pollen as they feed on nectar. Think agave and columnar cacti, which rely on bats’ long tongues and steady flight to set seed and keep genetic diversity flowing.
By adding a bat house, you create shelter near evening blossoms and moonlit borders. Even insect‑eating bats elevate ecosystem balance, supporting pollination indirectly by reducing pests that stress plants and by sustaining a healthier, more resilient garden web.
Aim for two to four narrow chambers with about three‑quarters of an inch spacing. Add a roughened interior and a six‑inch landing pad below entrances so bats can cling securely. Tightly sealed edges reduce drafts and help keep temperatures stable overnight.
Mount the house twelve to twenty feet high, ideally facing south or southeast to capture morning warmth. Ensure six to eight hours of sun in most regions. Clear approach paths help bats glide in smoothly during dim, twilight conditions.
Cut panels to size, rip interior spacers to three‑quarters of an inch, and score or add mesh to roughen surfaces. Screw, not nail, for longevity. Caulk seams thoroughly to block drafts, then attach the landing pad and partitions with precise, even spacing.
Look for guano beneath the house, faint staining near entrances, or dusk silhouettes testing approaches. Occupancy can take a year or two, so be patient. Share what you notice; your observations may guide other newcomers supporting nighttime pollinators nearby.
Monitoring, Patience, and Gentle Maintenance
Inspect annually for warped panels, loose screws, and failed caulk. Avoid opening houses during maternity season. Tighten hardware in cool months, refresh exterior finish as needed, and keep vegetation trimmed to preserve clear flight paths for nocturnal foragers.
