Are the bucket type swarm traps rain-proof?

 I got one of those swarm trap, looks like a paper mache bucket with a lid, with a hole in the lid. Are they water proof, or do you need to take it down, cover it up when it rains? We are expecting rain later today....

to a point.  i painted my with paraffin and beeswax.  they last much longer that way.  more beeswax than paraffin.
