Re-read the article. The 'big risk' isn't attacking humans (tho it's a concern), it's destruction of ecology and agriculture. If you're going to dig up and eat the farmers crops, doing at night is worse for the farmer. And there's another farm 100 miles away. Further, there's nothing in the article that indicates the hogs are less efficient at night. Since hogs already have poor eyesight and extremely good smell, there's no reason to believe night is much impediment.
