My brother had his own organic garden this year and all was going well until the squash bugs took over. Will Guineas eat these little pests? He doesn't want to use pesticides, so I recommended to get some Guineas....but I don't know if they will eat them or not. A squash bug looks to be in the "stink bug" family. The smaller ones will be gray and the older ones are a darker brownish color. He does have a handful of chickens too...so the Guineas shouldn't be all that hard to add into the flock.
