About a month ago I found a black widow spider in my mom's backyard. I caught her and put her in a small plastic container. She has been doing well, but, about three nights ago as I was making my rounds to feed my tarantulas, brown recluse, and black widow I discovered that my black widow has made an egg sac. Since it's been close to a month since I first caught her I was wondering if there was any chance that the eggs are fertilized. THERE IS NO CHANCE THAT A MALE COULD GET INTO THE CONTAINER AND MATE!!! Just wondering if it was possible if I might be getting some babies soon and how long does it usually take a black widow to lay her eggs after mating? Please help. Thanks and God Bless!!!
