Paper Egg Tray | 81 Cell Quail Egg

How many egg trays should I place inside my cricket container?

It is recommended to use as many egg trays as it takes to fill the entire floor space of the container, except for about 6" of space on one end for food and water.

Why do crickets need egg trays?

Crickets and other feeder insects such as Dubia roaches are territorial and don't typically live among hundreds like they do in captivity. Male crickets and roaches have a tendency to fight eachother, so giving them a place to hide within the pockets of an egg tray gives the insects a private place to hide.
Feeder insects are also known for nibbling and chewing, making egg trays are a great source of natural fiber that will not harm your colony.

Can this tray be used with feeder insects suck as crickets and dubia roaches?

Egg trays are a great source of fiber for your feeder insects, however the cells in this tray are very small and would not provide adequate surface space for the insects to hide.
