Spiders are a great insecticide

In a wooded wetland area, Buck Ross who farms near Arthur cultivates an environment for spiders.

He knows they are worth more than their weight in gold, holding insect populations in check.

A recent study cited by the newspaper, USA Today, says spiders consume 400 tonnes of insects per year – more than the global total of human meat consumption.

Spiders protect grasslands and forests by eating insects, says scientist Martin Nyffeler of the University of Basel in Switzerland, who is the lead author of the study.

He says their study for the first time puts quantities on the global impact of spiders, and he says they have a significant impact on insects, including pests.

There are about 45,000 species of spiders.
