has brought up a very important consideration in designing a bug farming operation: pests and predators (like mice).
Rodents, birds, reptiles, spiders, ants, wasps, flies and more can all be attracted to bug habitats, drawn by the warmth, scent, and promise of a meal. As a basic measure we have always kept openings to our insect habitats screened, and kept isolated from access by ants.
Since this is a general issue faced by all bug farmers, dealing with a whole host of different pests and predators, it seems appropriate to open a discussion thread dedicated to these problems and their solutions.
Here are a couple practices in addition to screening habitats:
-using cinnamon or vaseline "moats" to prevent access by ants
-maintaining positive air pressure in the farm unit to keep out small insects like mites and flies
