Foggers, or humidifier as they’re sometimes erroneously called, are often confused with misters. While the two provide water for chameleons, they are separate pieces of equipment that provide water for different purposes.
Why you might need a fogger
While foggers can really make your enclosure look spectacular with a fine mist settling over the plants, they are not an essential piece of equipment in the same ways misters are.
Foggers are not to be used as a primary hydration method, although they can help with this by forming dew droplets on the plants.
Running a fogger alongside a mister at the same time is not advised. Neither is running it all day and night as this can cause too much humidity and lead to respiratory infection.
Whether you actually need to buy one depends on how humid the areas you live is, how humid it gets at nightime and how dry your home gets in winter due to heating being on.
Getting one like this is certainly beneficial for maintaining nighttime levels, particularly in winter and regardless of what species you have.
The best way to use a fogger is to run it on the lowest setting all through the night if the nighttime humidity levels are low in the room your chameleon is housed. If they’re higher, you can adjust duration accordingly.
Shutting it off about an hour before your chameleon’s lights come on is best practice, and can leave the dew on the leaves for them to drink that I mentioned earlier.
