A single tree frog or American toad sheltering near your vegetable bed eats several hundred insects per night through the growing season. This setup costs about $5 in materials and takes 15 minutes to build. πΏ
A frog hotel is a terracotta pot filled with rocks, a small amount of standing water, and several short PVC pipe sections standing upright. Frogs climb in during the day for shade and humidity, then emerge at dusk to hunt. In the photos, green tree frogs are using exactly this setup β looking up from inside the tubes is one of those genuinely satisfying garden discoveries.
What you need: a wide terracotta pot (10β12 inches across), small smooth river rocks, enough water to cover the bottom inch of the pot, four to six sections of 1.5 to 2 inch diameter PVC pipe cut to 6β8 inch lengths, and optionally a small shade plant or a piece of burlap to reduce direct sun on the pot.
Building it: place rocks in the bottom of the pot to create a stable base. Add just enough water to cover the bottom of the rocks β a shallow puddle, not a pond. Stand the PVC tubes upright on the rocks, slightly angled or at different heights so frogs can choose depth and position. Place in a shaded spot against a garden wall, under a shrub, or tucked between raised beds. The key is location: full sun dries it out too fast and frogs won't use it.
Maintenance: refill the water every 3β4 days during dry weather. Rinse the pot monthly. In cold climates, bring it inside or empty it before hard frost β most tree frogs overwinter under bark and leaf litter naturally.
What it attracts: American green tree frogs, Pacific tree frogs, spring peepers, and American toads all use shelters like this in different regions of the US. Each one hunts a different mix of garden pests. πΈ
