I have a question! I've got spider webs hoping to all my plants. I recently had the lovely first experience with spider mites which ruined my gardenia bush, those were tons of little webs every where. What I have now looks jus like regular spider webing with a single web line going from here to there. My question is: If this is a plain ol regular spider is it doing any harm to all my roses and tomato plants, do I need to treat it or is ok to leave them alone? My logic was a regular spider might be helpful in keeping away and killing all the harmful insects...can someone tell me if I am right or wrong please!

Thanks a ton for any and all advice and suggestions! I love you guys here! Your great!
