I think they are kind of small, so a large zapper may not work as well.  They might get in around the edges, and it could be hard to notice where they have gotten in.  I think a small zapper might be more effective for this.  Just a good general suggestion: if you are going to be using a bug zapper, make sure you keep it plugged in.  If it goes out, the electricity stops flowing through it, so the bug zapper doesn’t work.

Do you have some place you can point the bug zapper that gets pretty hot?

How can I keep crickets out of my home?

I might try setting up a trap.  I’m not sure what kind of crickets you’re trying to catch, but maybe setting up a bug zapper could help?  It wouldn’t be fun for you to kill them.
