Hire a professional.

Or, if you insist on taking your life into your own hands here's the best suggestion to prevent paper wasps from coming back, from wanting to stay and keeping their babies from maturing.

WD-40

Plain and simple.

Every spot they come to at our house, I dose the nest when they're dormant and they never come back to that nest or that spot ever again.

I'm sure it's due to the oils in the spray but whatever the reason, it works!

NOTE: WD-40 will leave a darkened spot where you spray it (stain) through paint over wood.

I even use it for mosquito bites, but non-standard uses of the spray isn't endorsed by the manufacturer.

Whatever you do, don't use fire. http://www.cfnews13.com/News/Local/2009/10/29/beehive_believed_to_be_cause_of_big_condo_fire.html

I seriously suggest hiring an exterminator for this. Once you've managed to get spray into the hive, if any survive they'll likely come after you. Now you've got to rapidly get down a 15+ foot ladder while being stung by wasps, you could easily fall and hurt yourself badly. There's no effective method out there besides that spray.

Good luck.

It is a matter of urgency, you must call the professionals or the concern authorities because I think you must not do the taking down of those wasps yourself. Wasps are dangerous, don't wait for it to have in contact with you, it's just a matter of when.

I found an article about wasp trap, have a look at it, the site below:

If you live in an area where its cold this time of year(45degs or colder),the wasps are not much of a threat,their little bodies are starting to freeze and they wont try fling.If you can reach them with a broom handle while on a ladder,give that a try or see if one of your friendly neighbors has a ladder long enough to reach.Good Luck.

A pressure washer will do the trick. Spray the water, knock it down and run like Hell!

Rocket launcher...just make sure your insurance is paid for that month.. Slight overkill but it beats getting attacked by wasps.

A chemical known as Bifen IT is available at most Tractor Supply stores or farmer's feed mills. It is industrial strength and should only be used with extreme caution. This chemical kills bees, wasps, hornets, and pretty much any other insect that gets in its way. (This is why you don't use it on blooming fruit trees)

The applicator is a hand pumped sprayer, $20 at most garden centers, and when using it, the spray will reach upwards of 30 feet. I know because I have one and use this every spring to get rid of unwanted wasps and such. My granddaughter is allergic to bees and we have to clear the area every year. We live way out in the country where they seem to breed worse than the flies.

Spray the nest either early in the morning or late in the evening when all the wasps are home. Within a day, the nest will be empty and you can remove it any way you see fit.

Other than this solution, the only other way would be to hire an exterminator to come in and take the nest down for you.

Came here to say pressure washer. Only if you really don't want to use a professional.

If you are going to do it yourself, Make sure wear thick clothing and duck tape the ends. You might want to just duck tape most of your body so stingers don't penetrate it.

And from my personal experience - Get a couple of the large Raid cans that ONLY Shoot in a Stream. If you get the other kind it will just go in a cloud and then blow back in your face if its windy. Plus its not as fast acting as the stream.

Best of luck, but my first choice is still to call a professional!
