Yep, I think that putting repellent in the road is the best thing I can do to keep them out of the street. I will try to pick something that doesn't smell too bad and only put it there a few times to get the point across to the squirrels. Probably just putting that on the busiest intersections would be best so that it will stand out to them and not just seem like it's everywhere. I can also chase them out of the road whenever I notice them in it. Squirrels are very smart creatures and I wouldn't put it past them to be train-able. Maybe if I keep chasing them out of the street, a couple of them might catch on....

Other than that, I'm trying to think up additional ways to help the squirrels without irritating the neighbors or landlord... I feel very bad for them and want to do something.
