Insects and other creepy crawlies do not transmit Ebola. The virus does not survive in their bodies.
It cannot replicate on it's own. It is a thin protein shell with some DNA arranged in a particular manner which may change as it mutates. It can only replicate or reproduce inside a host cell.
By this fact, it is not a living organism. It is more like a chemical code which given the ideal environment, replicates in it's host until antibodies break it apart or it has caused an immune response such as elevated temperature which it may not like. The final outcome may be death, by which it goes back to it's dormant state in the environment.
