In the morning I lifted up the shade cloth from the cactus seedlings and found a slug slimming around the Mammillaria coahuilensis seedlings. I suppose the slug thought these would be the tastiest variety of seedlings to start munching on. The slug circled around the coahuilensis seedlings on the seed tray and then climbed down on to the seedlings and began to eat. It looked like I found this slug just before it had made its choice for breakfast.

I went into the house and brought back some tweezers and slug bate (Slug Magic) and pulled the slug off with the tweezers. I tossed the slug off into the flower garden and then put out some bate by the seed trays. It only takes a few days for one slug to become many slugs and they would clean out the seedlings in a few weeks or less. I'm happy that I found this one early enough to prevent the death of too many seedlings. The few seedlings this slug started to eat will likely die, because when slugs chew on plants they also cause fungal infections that often kill the plants too.
