Conservationists in Tanzania are using an unorthodox way of keeping elephants from wandering into human settlements - by throwing condoms filled with chilli powder at them.
The method has proved effective and Honeyguide Foundation, which hit upon the idea several years ago, with U.S.-based Nature Conservancy has stepped up its promotion, training volunteers in villages in north Tanzania to use a non-violent four-step way of protecting their homes and crops without hurting the animals. Previously many used spears to defend themselves.
The first two steps involve shining a torch at the trespassing elephant and sounding a horn. If it is not deterred, a so-called "chilli cloud" is thrown.
Chilli powder mixed with soil is packed with a firecracker into a condom, its end is twisted shut with just the fuse exposed. When lit, the condom bursts open with a bang, spraying a fine dust of chilli powder into the air. One whiff is usually enough to send an elephant the other way.
A last resort is a launcher that shoots a Roman candle firework into the air, producing a loud, bright explosion.
