A customer took a class where she was taught that blinking red construction lights repels beaver. I'm skeptical but... Has any ever used this technique successfully?

In one of the counties I trap, about 17 years ago, it was tried (before I started). From what I understand they thought it worked but the beaver became accustom and continued their work.

The landowner would always make jokes about the lights and the beaver, making fun of the application whenever I saw him.

I believe the beaver were initially repelled by the activity of the light instillations and the activity of the observations.

Kirk's opinions reflect my experience with repellents of most types. A new experience often garners a reaction from an animal whether it be good or bad, lure or repellent. But the natural cost/benefit analysis that follows will determine future behavior.

A dead beaver causes no damage. Bottom line, snake oil is just snake oil but a dead beaver solves the problem.

I once had to remove a beaver that was taking down all the ornamental trees and shrubs in a commercially developed area. The beaver was living directly under a major intersection (stoplight) in Litchfield (IL) where Old Route 66 and Route 16 intersect. It used the interior of the culvert where all the pipes converge for the den site. The bottom of the concrete "room" was filled with branches and then had the slivers of bark lining the floor, just like in a regular beaver lodge. It would go out all the drain culverts, some round about 30-inch diameter, and some square about 4x4 feet. It took down all the trees in front of the Gardens Motel, then took all the trees at Taco Bell, and finally worked its way about 1/8 mile to Pizza Hut where it was working on their shrubs. It would cut these trees and shrubs only 15 feet from the entry doors and parking lots while traffic was active and customers were walking by, then drag them all the way to the intersection and into one of the culverts or drain pipes. It could care less about the stoplights (red, green or yellow!), car and truck lights, business signs, or anything else that people "think" would bother them or scare them away. Too many people assume that animals think like humans. Wrong.

any spotlight is a beaver repelling light no matter what color , when it it quickly followed by a fast moving dose of lead ......

People love the idea of repellants, some because they think they are humane, most because they think it will be cheaper than hiring someone.

If we all had the loot those guys selling deterrent systems have we'd all be writing our posts from an island paradise sipping drinks and watching
our money grow.

So many things can bother a species of wildlife, the problem is as we all know very few aren't realized to be harmless by the species in short order
leaving it worthless.

If I had a dollar for every electronic bird screamer I've seen in the last few months I could skip working this winter, seriously, they are everywhere
and so are the birds who are still on site....

Hard to convince folks, just like the cure all moth balls (napthalene)!

Just heard on Klick & Klack (The Tappet Brothers) that our old panacea, mothballs, were recommended for mice in a car. In a car!

But Dave.... The car thing makes some sense. The owners are already in the vehicle which they can drive to the ER!

What Mr. Scheller failed to tell you is that he and others from Illinois are responsible for ALL of our beaver problems in southern

Wisconsin. We never even knew what a beaver ( the animal kind ) even looked like 25 years ago. They all came up the Fox river from

Illinois to avoid getting caught by Mr. Scheller, Mr. Erickson, and other talented Illinois trappers. I would complain more, but a

few years back, we sent them most of out Liberal politicians. I figure that pretty much makes us even.
