looking for info on organic/natural methods of pest control for guerilla type gardening (Midwest us). Don't like the idea of pesticides and would prefer to avoid fencing as well.

Pest Control? souds like rabits or deer to me. First I thought neem oil then when I saw "fence" I thought Pee. Don't know, search it. that's what I'd do.
chicken wire is light and you can weave grass and leaves into it.

depending on how often you go out the pee idea is probably a good idea in addition to any other methods you use, you could collect it for a few days before you go out and use it all around your site, the sent will help your other defense's work better by 'marking your territory' and deterring some animal's from going farther.

rotten really rotten eggs i hear work wonders. Also not sure if im spelling it right, but there is an organic pesticide called atrazine. Its what i have and it cost close to 130 a bottle. But this stuff is the best damn pesticide on Earth imo. It's organic and it will get rid of ANY pest problem, regardless of how infested your crop is. Just dont use it when your budding.

thanks guys

I don't think Atrazine is an organic pest control. A little bit of Googling and I got an EPA warning.

Salt around the perimeter on the ground of the plants will keep slugs and snails away for sure,
Do you think rotten eggs will attract some animals, they seem to eat anything that is eatable, but maybe nothing will eat rotten eggs!! good idea though.
