I will like to know what critters are really bad for your Garden? I am sure there are different kinds for each states ! As for Arizona I think ours are gophers, and grasshoppers.... I am just curious !!!
In my part of IA the list is LONG..... Groundhogs, racoons, deer, rabbits (sometimes the dog, too!) so many insects....Hornworm, cutworm, aphids, slugs, grasshopper, japanese beetle , viner borer, potato beetle .... are among the most plentiful.
The neighbors tolerate the cottontail rabbits. One neighbor said that he had zero beans last year. Maybe he will do something about the brazen bunnies this time!
Marmots - large groundhogs - can be a real problem but they seem to be fairly stupid critters. They also seem to be able to live on most any plant so they will eat grass and such and it may take years before they figure out that cabbage can make a pretty good meal! Once they figure it out tho', a 20# squirrel and his family, can eat a lot of veggies. I have the neighbors convinced that they cannot tolerate the marmots, at least .
Ground squirrels will turn the landscape around their burrows into moonscapes! However, since they have fairly easily accessible burrow entrances, it is fairly easy to block them with stones . . . driven down with a short piece of wood and a sledgehammer :/. Someone once pointed out to me that they live for 6 months, never coming out of their burrows and they can dig. Well, yeah, I don't know if I'm killing them or just convincing them that they should move - just as long as they don't lay bare my garden!
I've just mentioned the flea beetles & my problems with them on Joz' topic. Sometimes they aren't really so bad. Colorado Potato Beatles can mean disaster for some plants if given the chance. They get started in the nightshade weeds, which grows everywhere in the fields of sweet corn around about.
The cabbage moth caterpillars can be real bad some years. I'm becoming reluctant to grow cabbage because of all the problems it can have with these, and aphids. Bt spray can kill the caterpillars and even tho' insecticidal soap can do a good job with aphids, reaching them with the spray is real tuff in the cabbage.
Cucumber Beetles and Southern Corn Rootworm beetles give me grief every year.
I also have a lot of trouble w/ caterpillars of all kinds. Partly because of the trees at the backside of the garden.
I also have oodles of tobacco horn worms on the tomatoes every year ... they become duck snacks.
Perhaps my biggest problem bug tho, are rollie pollie pill bugs. They take down seedlings and even mid-sized plants, eat through radishes & carrots, and truly just gross me OUT.
And of course I also have troubles with squash bugs.
And APHIDS.
Just lately, it's been my cat. I guess the raised beds look like giant litter boxes to her. My puppy is pretty rough on it too, when he runs after the cat...
