Maintaining humidity in
your Rainbow Boas cage
Being from tropical rain forests, Rainbow Boas
require high humidity. There are three basic factors to humidity:
Evaporation - is the process of water molecules
Dissipation - The natural tendency of airborne water
particles is to spread out as far apart as possible.
Condensation - warm moist air contacting a cooler
surface will cause the water molecules to condense into droplets on
the cool surface.
The number one mistake made with rainbow boas is to
give them lots of ventilation. They really do not require much
oxygen. They’ve even been reported to submerge under water for up
to 30 minutes at a time. That ventilation will allow all those
precious airborne water molecules to dissipate into your house.
Unless your house is humid, many more will leave than enter. This
will result in the enclosure drying out.
Many keepers use misting regimens to keep humidity
levels up. IMO, you need to set up the environment so it will
automatically be humid. Here are the steps I take to provide that
1) LIMIT VENTILATION - my adult rainbow boa cage sections are
around 6 cubic feet and only have one two inch round vent. More
than enough for air exchange.
2) Provide LARGE surface area water bowls. Remember,
the larger the surface area, the more water will evaporate.
3) I provide damp hide boxes. A sweater box size for
adults with holes in the sides. An inch of peat moss and another
inch of green moss. All kept damp
4) Depending on your enclosure you can fine tune your
system by moving the water bowl around. Closer to the warm end and
more evaporation, closer to the cool end and less.
