FRANK, I guess it's too much to hope that this would repel MOSQUITOS too?... Elst they'd be selling P-U Insect Repellant instead of OFF by now? I'm covered in bites ...and Wpg has found a nasty sign of West Nile in a bird. Mosquitos are pretty unnerving these days, not just a pain.
BTW, if you're serious here, I would expect manure to attract insects rather than repel them?
