What would a killer bee habitat look like?

Answer 1

There isn't one. Killer bees are more properly called Africanized honey bees and are the result of a cross between 26 Tanzanian honey bees (apis mellifera scutellata) which escaped from a research station in Brazil, and local Western honey bees drones (apis mellifera mellifera).

Answer 2

The so-called 'killer bee', more properly called the Africanized honey bee, looks exactly the same as any other honey bee, and lives in the same sort of places, from small caves to holes in trees -- and, of course, man-made hives.
