Hello and welcome to frog forum!!! Yikes, looks like a nasty infestation.
For your frog(s), i recommend quarantine for two reasons. First, so they can be out of the way when you clean and disinfect their enclosure and second, so you can monitor and make sure they haven't been adversely affected by the pests
throw away the substrate, trust me, it's better this way unless its something non disposable and cleananble.
All decor that is not alive can be boiled for 20 minuted to kill anything living on it
For live plants, try taking them to a room that you don't go into often. Wipe those eggs and webs off of them and spray them with apple cider vinegar. You can do this with the plants on your windowsill as well. Spray them once a day with the apple cider vinegar (put them on a tarp or else the stuff will stick to surrounding objects) for a week. Then uproot them, wash thoroughly and re-pot with NEW SOIL. That should solve it
Hope this helps
