Wasp Houses

Here are my two Wasp Houses......no takers for 10 yrs.  Oh well, they still look nice in the garden.  My granddaughter and I painted them with acrylic paint last winter and they have held up pretty well.  They were given to me by my next door neighbor as bird houses but they are too small for that.  I think they are meant to accompany flower arrangements along with artificial birds.  I used to nail inverted 1 lb coffee cans to wood posts and have plenty of caterpillar eatin' wasps take up residence in them.  I was always afraid I would bump one and suffer a painful volley of stings.  So I didn't grow anything near enough to them for that to happen.  That was out in the country were I kept a 100x50 ft vegetable garden as a deer feeder. :)
