Can slugs kay eggs in a jar?

Yes, slugs can lay eggs in a jar. Slugs are hermaphrodites, meaning they have both male and female reproductive organs. To reproduce, two slugs will come together and exchange sperm. The eggs are then fertilized internally and laid by the female slug. Slugs can lay eggs in a variety of places, including soil, leaf litter, and even in jars. If you find a slug in a jar, it is likely that it has laid eggs there.
