These parasite resistant cages are a great size for rearing small groups of caterpillars on cut or live food plant, while protecting them from wasps, flies, and the occasional hungry praying mantis. Also a great tool for releasing butterflies or hatching pupae inside.
A single zipper and no vinyl window make viewing and cleaning very easy. After years of using pop-up cages like this we've found that the black mesh makes it much easier to see what's inside. White mesh reflects too much light, making it difficult to see the bugs :)
These have zipper protection, which is an inside flap that covers the zipper when closed. This prevents caterpillar injury if resting on the zipper during opening/closing.
For cleaning, soak entire tent in a mild bleach solution for about an hour. We use about 1/2 cup bleach to 5 gallons of water. Rinse and dry thoroughly before reusing.
