About 150 years ago when I was a kid I went to a summer band camp in the Texas hill country. We had a watermelon eating party on the tennis court one evening and then went inside for a program. Upon leaving the building we noticed MANY 'dillos on the tennis court feasting on the left over watermelon. With that sight etched in my mind I've recommended watermelon to a number of my city friends as a good bait for the 'dillos ---and virtually every person has reported that they were able to pretty quickly catch them in the "have-a-heart" traps when baited with watermelon. If I really had a problem with them on my little ranchito I'd bust up a bunch of watermelons about an hour before sunset and then stand by with my favorite varmint rifle.
