I know the feeling. The first year we had chickens and I let them free range, there were so many grasshoppers that the hens just stood there like bobbleheads, watching the millions of grasshoppers jump everywhere.
This year I saw a bunch of baby grasshoppers in the garden, so grabbed the soapy water and started spraying (1 to 1-1/2 tsp dish soap in 1 qt. of water, add a few drops of any cooking oil and shake before using). That helps to keep the bugs from totally destroying the plants.
The past few days I have directed the new hens into the garden and yesterday there were a lot less grasshoppers in there. I mulch heavily with straw, so they do a lot of digging and scratching, but usually don't tear up mature plants. They have scratched up a couple new potatoes and ate a bunch of beet tops, though.
I've noticed that we have less bugs since I let my first batch of hens (all 8 of 'em) free range a lot the past couple years. They find insect eggs, etc. Last winter we were down to 2 hens, so they sure didn't do much. Now we're up to 12, so I hope they gain some ground!
And for sure, some things have to fenced off, like my dinky strawberry patch or anything newly planted. My garden is fenced, so even if they can't get in there, they're still getting bugs that would hop in the garden eventually.
The soapy water didn't do anything for my variety of squash bugs, other than give them a bath. You can also add Tobasco sauce, garlic juice and peppermint to the mix, but I haven't tried it. Last year I saw Neem at Lowe's, but I haven't been there this year to see if they still have it. I have more trouble w/ squash bugs now than anything. :/
