A fine mist spray bottle is the single most frequently used accessory in ghost mantis keeping. You will use it at least once or twice daily to maintain enclosure humidity and provide drinking water for your mantis. The quality of the spray bottle matters more than most keepers realize — a bottle that produces a coarse spray will dump large water droplets that pool on the substrate and promote mold, while a bottle with a true fine mist nozzle creates the delicate bead-like droplets that mantises prefer to drink from.
Look for spray bottles with adjustable nozzles that can be set to the finest mist setting available. Bottles marketed for plant misting or hair styling often produce a finer spray than general-purpose cleaning bottles. Glass bottles with brass nozzles tend to produce a more consistent, finer mist than their plastic counterparts, though either will work if the nozzle quality is good.
For keepers maintaining multiple enclosures, a pressurized pump sprayer designed for garden use can save time and produce an exceptionally fine, consistent mist. These sprayers are pumped up to pressure and then deliver a continuous mist stream at the press of a trigger, allowing you to mist several enclosures efficiently during your daily care routine. Choose a sprayer with a capacity of one to two liters, which is more than enough for a mantis collection without being unwieldy.
Always use dechlorinated or spring water for misting. Tap water in many municipalities contains chlorine and chloramine, which can leave mineral residues on enclosure walls and may be harmful to invertebrates over time. Letting tap water sit uncovered for 24 hours allows chlorine to dissipate, or you can use a water conditioner designed for aquarium use to treat tap water immediately before misting.
