These popup cages are parasitoid-resistant and made of extra-fine polyester mesh netting to keep the good bugs in and the bad bugs out! The mesh is easy to see through (though, unlike the square mesh cages, the round cage does NOT have a plastic viewing window). This cage opens on the top end of the cylinder, with a zipper that goes the whole way around for wide-open access. There is a fabric carrying handle on the zippered end, which makes them especially convenient for hanging.
They are washable, reusable, and collapsible for easy storage. The handle can even be doubled around the collapsed cage to hold it shut. Dimensions are approximately 5-1/4” wide (diameter) by 7” tall. These round mesh cages are only available in white with green trim.
