Balancing performance and cost when migrating from monoliths to microservices

[Timothy_R]

I'm attempting to build a custom, insulated nesting box for a small colony of endangered native bees that I'm trying to establish in my suburban backyard, which is surrounded by non-native flowering plants. My budget is under $100, and I plan to use untreated cedar and natural reeds for the nesting tubes, but I'm struggling with the internal design to prevent mold and parasitic mites in our humid climate. The box needs to be south-facing, mounted about four feet off the ground on a post, and have a removable back for monitoring without disturbing the larvae, but I'm unsure about the precise diameter and depth of the tubes for this particular species, and how to create a waterproof yet breathable roof overhang that won't trap condensation. I need to have it installed before their active season begins in about five weeks.

Since the species isn’t fixed, build a mixed-tube box: holes 6–8 mm dia, ~150–200 mm deep, plus a few 4–5 mm and 9–10 mm tubes for related bees. A removable back for inspection; a shallow, sloped roof with a 2–3 in overhang to shed condensation. Line the interior with inert material to limit leaching, watch for mold and mites between seasons, and mount south-facing at about 4 ft.
