One can usually purchase bear spray at any outdoor supply store, specifically ones that cater to hikers in areas where grizzly bears are present. (It can be carried in checked luggage, too, as long as it's "not greater than 2% capsicum". I wrap it in a printout from the TSA web site that states this whenever I pack it for rocky mountain trips.)

You gave me quite a laugh. Yes, there are neighbors who would comment if I suspended my garbage can and let it swing in the wind, but they may just join in! So far the bleach is working. There are also the neighborhood skunks, racoons, possum, loads of deer, and even rattle snakes. By the size of the tracks, however, this critter has me the most concerned. Thanks!

Like in comment #1, we freeze our scraps. We have not had a problem with our bears since.

While I don't deal with black bears in the northern suburbs of Buffalo, NY, I do have to deal with skunks and raccoons, which can be quite agressive, create a mess when scavenging and potentially carry rabies. My local animal control officer suggested placing cloths soaked in Pine Sol under the deck, where these animals shelter, and on the containers. I also secure the lid with a bar of 1/2" EMT, long enough to prevent the can from rolling, even if tipped over. And, the suggestion to keep meat scraps in the freezer until garbage day is a good one, which I also use. Since these are crimes of opportunity, we need to minimize the opportunity. The Boy Scouts suggest suspending foodstuffs from a tree branch, well out of reach, though the sight of a garbage can swinging in the wind might invite comments from your neighbors. In a more rural setting, I might deal more directly with the culprits, ala 22 cal lead poisoning, but in a suburban setting, prevention is the best recourse. Good luck! Paul H.

What I don't need is a ticked off bear! The bleach is working. No problems this week. Tomorrow is garbage day so we'll see if anyone on the street gets hit. Where do you buy bear spray?

Evidently there was a study conducted in the '70s with Polar Bears and ultrasonics. The result was mixed at best. The summary suggests it will stop some of the bears some of the time if the sound is loud enough and in the right frequency range. I saw another discussion about Zapping them with a taser or similar. Evidently their fur and this skin make that much less effective than on humans....it just manages to tick them off. The one method that does appear to be somewhat effective is bear spray. If you had a motion sensor and some way of warning off humans, you could spray them when they approach the cans.

I like both of these ideas - the bleach will be immediate, while the ultrasonic device makes long-term sense. I saw this update on the bear condition up here where I live this morning. Pentz Road is about three miles away, but we share the same canyon: http://www.paradisepost.com/ci_18802160?IADID=Search-www.paradisepost.com-www.paradisepost.com

I use ultrasonic devices, purchased at Home Depot, to keep mice out of my house. Perhaps some research into how well they'd work on bears would be in order, or whether you could construct a larger, more powerful untrasonic driver and transducer arrangement to deter them. And, you won't chance splashing anything onto your clothes!

I keep animals out of my trash by spraying Clorox into the trash bags before putting them outside. Watch out for the overspray, as it will bleach your clothes! I've also used gasoline, but that's a bit dangerous for obvious reasons. I keep an 8 oz spray can of 2% pepper spray (aka "bear spray") handy, too. I haven't had to use it, but I suspect that a couple of hits with it would condition the bear to avoid my place.

1 You absolutely must buy a bear-proof garbage container. http://theblueridgehighlander.com/Black-Bears-of-the-Blue-Ridge-Smoky-Mountains/In-Pursuit-of-the-Black-Bear/index.php That won't be the last bear otherwise. It's very wrong to feed bears the way you're doing, as explained by others above. Your current bear probably already needs to be destroyed. The basic problem here is that there's way too many people.
