This is what grew in my garden shed this summer. Friends said I should get rid of it, but wasps are good for pollinating and they help with insect control. This is the nest of a paper wasp.
It started as a tiny nest but ended up to be about 35 cm. from top to bottom. Now the wasps have gone, since we already had a frost here. Wasps live only for a year, except the queen. She will build a new nest next year.
For more about paper wasps, the magazines Gardens West, Gardens Central and Gardens East have a great article on it. Go to http://us6.campaign-archive2.com/?u=c72643729204be7292d82041a&id=c93476f3d2&e=%5BUNIQID%5D
