I would say go right ahead. They won't survive the trip through the tubing. I've sucked up bees, flies, ladybugs, stink bugs...never a problem.
One time I became aware of an active hornet's nest in the attic above the garage at my parents' house. I crawled up there with a headlamp, a can of Raid Wasp & Hornet spray, and the central vac hose (probably two hooked together to reach; no inlets in the attic!). Was able to spray some and suck up others all at the same time.
No survivors in the bag when I carefully checked after the job was done.
