I was very surprised at the effectiveness of the wasps also, since it was not apparent until the following season when no MBBs showed up. There is hardly a hole in the leaf of any of the beans in the entire community garden, whereas last year it was mass devestation. I am unable to find any MBBs at any stage of growth, adult, eggs or larvae. In the mean time, I suggest rotenone or sevin. They work as a short term solution. BTW, if you use the wasps, pay close attention to the timing of that method. They are most effective when released at the right level of MBB infestation. Jim

Look at my comment on the WV 2000 Beetle below.

Sadly, the day of the economical to operate motor vehicle is over. The car or truck are slowly becoming luxuries rather than necessities - thanks to the environmentalists and safety nazis.. Other than a very expensive trip to the dealer(but some of this may be covered under warranty) the only other thing the car owner may or can do is assure that the battery is suppling the vital 12.0 volts(minimum) to the computer...

Last year when we were remodeling when they took off the old siding there were millions of the asian beetles underneath. It was disgusting. I sprayed the sides of the houses as far up as I could get standing on the ground. The ortho sprays a fine mist and a little goes a long way. I bought the gallon size that comes with the pump type sprayer and have been using that same gallon for several years. So yes, I think you could get enough on the side of the house. I didn't spray the ground either because of the kids and animals. Put the DE around the house. It should cut down on them substantially. They are combining east and west of my house today. Curious to see if I am going to get inundated with them soon! I bought my food grade DE online. I shopped around and figured price per pound with shipping figured in. This place I linked below had the best price last year. I bought a 10# bag for $25 and have a lot left over. I too thought of using it as wormer for the outside cats but haven't tried it yet. Not sure if the local farm stores carry it. I guess I never really checked. Maybe call the feed stores. They might have it or somewhere like Theisens/Tractor Supply? But I didn't think $2.50 a pound was too bad. It is a fine dust so it goes a long way as well. I will email my "organic" friend and see where she buys her DE. Hope that helps Pinch! When those beetles invade it is awful! Here is a link that might be useful: Diatomaceous earth
