War of the Birds

Although not quite as scary as Alfred Hitchcock, we definitely have a bird problem going on.  As I type this some robins are building nests on the roof rafters in the back of our house.  This has been going on for more than a month and we thought we had them beat by knocking down their nests whenever they started (before they laid any eggs), until yesterday when...
Of course I knocked this one down as well, but I finally broke down and ordered plastic bird spikes which hopefully will deter them from their home-building enterprise for a while.  I'll let you know how they work when we install them next weekend.  Until then, the war continues.

Let me know about your bird or rodent combat success!
