Cats will not like it because it smells like the flea drops and the yellowjackets will carry the tuna back to the nests and poison all the larva and queen.
Do not mix too many flea drops in the tuna or the yellojackets will die before they bring back to the nests.

That's a great idea. That way you can kill nests that you haven't even identified. Excellent. Thanks! Although it will deprive me of the joy of directly killing them.
