Pest Attack In My Garden

I want to take help on some pest attack on my plants. I haven't any picture right now because when ever i step out to find then. I find nothing. These are creepy and bad monster like. I see some webs out there and i know they are spiders. But wanted to know is spiders bad for my plants. If they are then how can i get rid of them?? Help please

Out of tens of thousands of spider species, only one is known to be herbivorous.

I'd think that by eating potential pests, spiders do vastly more good for your garden than bad.

There are other garden pests, though, that make sort of fibery things on your plants and aren't spiders.

Mia, the majority of people posting here are from North America, and mostly from near Chicago (though not all) so we likely have wildly different sorts of flora and fauna to you!
