Secure the room and start looking up
A White's tree frog in the first hour has climbed, not run, so secure the room and direct your eyes upward from the start. Close doors and windows, block the door gap if there is one, and keep cats and dogs out, because this frog's defence is stillness and a paw swipe is its main indoor danger. Fetch a step stool and a torch before you begin, since the likely refuges — curtain tops, wardrobe roofs, high shelves, and the space behind a boiler or water heater — are all above head height. Ready a ventilated tub lined with a damp towel and wet your hands before you start.
Work the damp refuges in a set order
Search a White's tree frog's refuges in a fixed order so none is missed: first its own vivarium plants and any houseplants in the room, checking pot rims, drainage saucers, and leaf axils where a heavy frog wedges itself. Move next to water — inside and behind sinks, along shower fittings, behind the toilet cistern, and in the laundry tub — because a White's tree frog out overnight will seek that moisture. Then check warm, high, undisturbed spots: the tops of cupboards, behind picture frames, inside lampshades, and along curtain rails. Look for the frog's broad, still silhouette and pale belly pressed to a surface, and remember it may have darkened to brown, so search by shape and size rather than by green colour alone.
Coax, do not chase, when you spot it
A White's tree frog is famously unhurried, so a calm capture in the first hour usually succeeds with patience. Wet your hands, approach slowly, and slide one hand in front while guiding from behind, or hold the damp-lined tub beneath it and encourage it to step in. Never pull a White's tree frog off a surface by a leg, because its toe pads grip hard and a tug can injure it; a gentle nudge and a few seconds of waiting normally releases the grip. Once tubbed, check that its skin looks moist and unmarked, offer it the chance to sit in shallow clean water back in the vivarium, and secure the lid properly this time, testing the catch with a firm pull.
Set the room for an overnight return
If the first hour ends without the White's tree frog, arrange the room for the night instead of dismantling it, since this frog will move toward water and food after dark. Leave the vivarium accessible with its water dish full, set an extra shallow dish of dechlorinated water on the floor beneath the plants, and keep the room door closed and pets excluded overnight. Listen in the evening if yours is a calling male, because a croak from behind furniture has ended many searches. Recheck sinks, pot rims, and curtain tops by torch before bed and again at dawn.
Widen the search if it reached the garden
If a window stood open, extend the first-hour search to the foliage, pots, and damp shaded walls just outside it, and check any outdoor sink, water butt, or stacked plant trays, because a White's tree frog settles into the first cool, wet wedge it finds. Tell neighbours with a photo that shows its size and skin fold, and ask them to check their bathrooms and laundry areas too, since open windows connect those rooms between houses. Ask any finder to keep the frog in a ventilated tub with a damp towel and wet hands only, and to call you rather than releasing it. Through KinsLe, the Lost Pet Alert System sends a free alert to nearby Circle of Love members and lets a finder message you directly, so that call comes while the frog is still sitting where it was found.
