I've also had good results with onslaught. You have to get them early. They feed on one thing in the spring and change mid summer to another. Seems like cat food works part of the year and fruit juice another. Water supply is another good bait site for wasps. I live in a dry area and they are super attracted to water.
Birds: best luck I've had so far is a kite type owl decoy on a very long PVC pipe. Any breeze and they appear to be flying. Move it (actually several) around. Don't leave it in one place very long. Birds ignore stationary decoys
Deer: A motion detector hooked to a cheap boom box. Tune it to a loud talk or rap station and put the volume high. They get used to repeated regular noise like a cannon but not the radio. Works day or night. All is quiet when they start coming then BOOOM they run for cover. If you have a pesky deer that hangs close, I have an electronic varmint call, turned loud and run a couple minutes of cougar screams. They will leave the area for a day. Coyote howls work fairly well too. (neighbors dogs, or yours, will not like it either and get agitated)
