This product is expensive and doesn't eliminate heavy webs after multiple uses. Does seem to kill spiders.
Expert response: Thank you for your comments! If you already have existing webs, then you will need to physically remove them; the Cobweb Eliminator will not eliminate webs that are already there. It will kill insects and spiders on contact and prevent new cobwebs. Please let us know if we can further assist you!
Gave it two stars since I seen a reduction of amount of spiders but not sure if it’s because of the cold weather other wise about a quarter of the amount came back and it doesn’t seem to bother them when sprayed
