Please help me know what to do about this problem. My back lawn in the SF East Bay Area is FILLED with what I have identified (thanks to this website) as European Paper Wasps. The one I caught to do the identification had a very small spider/mite type creature in its mouth. It kept it in its mouth until it stopped flying, and then shuffled it around in its mouth. Finally it spit out some unidentifiable parts, and worked on cleaning its own legs. The wasp is sensitive to my movements and responsive. Very interesting.
These wasps hover above and land in the lawn mostly, sometimes landing on trees or ivy. I cannot locate a nest. (we do have a blue mud dauber nest at our front porch) I have been ignoring the wasps as much as possible, and haven't been stung, but there are more and more every day. It is somewhat terrifying now, like walking through a light swarm. There are so many now, I don't feel safe cleaning up dog poo or watering my plants except at night.
Everywhere I read or ask, I seem to get ignorant information--I tried a can of spray poison today with little success. I would need dozens of cans to kill all these wasps--and I would rather not kill them or use chemicals. Will someone knowledgeable please help? Can I get them to leave, or is it hopeless without chemicals. What do you recommend?
