At some point we all have a problem with pests in our gardens. But, most people feel some connection with nature when gardening, and while they want to get rid of those pests they don't want to harm the critters in doing so.

So what are some humane ways to get rid of garden pests? Basically, you need to make them uncomfortable in some way, but not necessarily in a painful way. You can offend one of their senses, but at times doing so offends yours as well.

You can try repellents to scare garden pests away, using scents from predators like fox urine, but that will only repel certain garden pests, and the repellent can wash away in the rain.

You can try a repellent like pepper on the plant surface, but that means the deer or other animal would have actually eaten some of your plants already.

Imagine that you could only stand guard at your garden with a simple garden hose with a sprayer attached, you could be sure of scaring off the most persistent of pests if your were to suddenly spray them for just a few seconds when they approached the garden. And if you were to consistently do so for a week or two, the pest would eventually get frustrated enough to move on. This would work with almost any pest, including deer, dogs, cats, skunks, herons, and even armadillos.

If you could only set this up to be automated, and to work both day and night it wold truly be an organic pest control that would be an effective repellent for all sorts of garden pests. This is the basic idea behind the Scarecrow Motion Activated Sprinkler system. This system has a motion detector built into a sprinkler head, that will automatically spray the intruding pest for just a few seconds, repelling your garden pests while doing them no harm.

So this concept to repel garden pests sounds deceptively simple, almost too good to work. Does it really work that well?
