Hmmm, I have never heard of either of the predators you are using. I googled longiepies and got nothing. I googled Californiums and only found info on a synthetic element. I was wondering if either of the natural predators created their own webs but cant find info on them. I would remove the webbing by hand for definate. I would also be tempted to bug bomb it... this will kill the natural predators to though. I would let the space airiate big time before introducing lady bugs. They are an age old enemy of the spider mite and I can guarantee they work. This is only what I would do in your situation. Maybe someone knows of the natural predators you have used and can help you more. The pics are mad.... scary, creepy mad!
