I bought some of this last year, and used it stretched over hoops as if it were row cover to keep deer off the swiss chard and lettuce. It worked beautifully; so I bought some more. It worked most of this year, too. Then in late September I went out to harvest chard for market and it was all gone. One or more deer had discovered that they could break through the Deer-X; it was ripped all down the middle, and footprints made the culprits obvious. So I guess I have to find some sturdier netting for next year; or else give up on the chard again. But at least I got nearly two years’ worth of harvests with the Deer-X; so people might well find it worth a try.
I have used this netting for several years now, in a number of different applications. It holds up well against UV damage and as long as it is properly secured, will keep a number of pests out. It is lightweight and much less expensive than similar products available at big box stores. The one drawback to using this netting was that large snakes attempt to crawl through it and get caught. They are not hard to release, but you have to clip a few squares in order for them to have enough space to finish crawling through. The snakes are there to feast on small rodents, though, so it's in your best interest to pay attention to your fences and help the snakes when they need it. I honestly find it very difficult to garden without this netting.
