Maybe they were not as sweet as others? Maybe there is something tasty in the bin that is getting their attention. Gosh I hope there is not something wrong with the watermelons because us people want to eat them too.

eq2: that's my concern. I was thinking about them being sprayed to keep fresh longer. I did wash them (the watermelons) with soap before cutting.

I've put rinds from two seedless watermelons from the stor so far this summer and the worms are going through them like worms on watermelon.
Man, watermelon is expensive and good, what are you doing letting them go bad without eating them yourself?

Niivek: Yeah, you're right. They are sooo expensive this year, almost double of last year's.
""what are you doing letting them go bad without eating them yourself?"" It is weird but having worms didn't make me feel too bad when stuff went bad, at least the wormies will have a treat, so I thought. Besides, this is one of the reasons why I started worm farming back in 2008.
