Why a spray in the next room is a frog problem
A frog does not experience the air the way you do. Its skin is a working organ: thin, moist and deliberately permeable, because the frog breathes and drinks through it. Whatever settles out of the air onto that skin — perfume oils, hairspray solvents, the chemicals in a surface cleaner, scented candle fallout — is absorbed rather than brushed off, and a humidity-loving species kept in warm, damp air is coated in exactly the moisture that helps contaminants dissolve and pass through. The dose a human registers as a pleasant scent can overwhelm an animal weighing a few grams whose whole body surface is an open door. This is why frogs sicken after redecorating, pest-spraying and party nights in ways owners struggle to explain afterwards.
Set a hard rule: nothing sprayed in the frog room
The protection that works is geographic, not careful spraying. Nothing aerosol or fragranced gets used in the room the frogs live in: no perfume, aftershave, hairspray or deodorant spray, no air freshener, no fly spray, and no spray-bottle cleaning while the tank is in the room. Guests apply their products in the bathroom with the door shut and give it a few minutes before wandering back, and the same rule binds you on ordinary days, not just party days. Keep the tank's lid or mesh top in place as a partial barrier, site the enclosure away from the room's doorway where drifting spray enters first, and wash your own hands after using any scented product before you open the tank or handle the frogs' water.
Handle cleaning days as a small evacuation
Sooner or later the frog room itself needs a proper clean, and that is the day the frogs travel. Move the whole enclosure, or the frogs in a secure ventilated tub with damp paper towel, into a room that will stay clean-aired, then do the spraying and scrubbing in the empty room. Favour plain water, a cloth and elbow grease over chemical sprays anywhere near amphibian housing wherever you can, and where a product is unavoidable, ventilate the room thoroughly afterwards and let surfaces dry fully before the frogs come back. Clean the tank's own glass and fittings with water alone as a standing habit, so chemical cleaning stays a rare, planned event rather than a weekly exposure.
Make sure the rule survives you leaving the house
Most frog-versus-spray accidents happen when the keeper is out and a guest, sitter or family member tidies up helpfully with whatever is under the sink. So the rule has to live somewhere other than your memory. A note on the tank helps, and the no-spray rule is worth repeating out loud to anyone staying over, so it does not live only in your memory.
