Goats are much more effective than their human colleges and even chemicals in many situations. They are able to work on terrain people cannot safely work on and are able to control invasive plants and even poison ivy better than chemicals. Please check out the University studies and the EPA's results (we are The Goats at the EPA in Narragansett, Rhode Island) listed here. Goats are even helping to increase bee population as noted by the EPA. The joy the bring to any job is priceless, but we understand everyone likes results, and that's exactly what Goatscaping provides, proven, environmentally sustainable results.
