Over the course of many, many, years. Humans learned to deal (somewhat) with the Zeharu problem. They used and still use, one of two methods:

1) A specialized net, the wiring on it is razor sharp, and the weight of it falling down is enough to shatter a Zeharu's scales. Which is where the razor wiring comes into play, the humans coat it in a specialized liquid, once the liquid comes into contact with flesh it starts to work its magic.

It'll start by nullify the Zeharu's abilities (fire, lightning, acid, etc...) nearly instantaneously. It goes right into the Zeharu's bloodstream and that's where problems start to arise for the Zeharu. They'll feel their limbs turn to jelly and their eyelids fall heavy.

Any Zeharu knows, once you're caught in this net, there's usually no getting out and not many ever wake up again or are at least seen again. It's hard for any Zeharu to save another from this net, as the net is extremely heavy and the wiring can slice right through a Zeharu's claws. It would take 3 full grown Zeharu to save one under the net or it would take Orion.

The balls on the net are the weights, each weighing over 200 lbs. The balls are made from black steel and inside are filled with concrete.

Orion purposely got himself caught in this net one time, he wanted to know what would happen... He learned a very painful lesson from it and never did it again.

These nets are usually set up at the entrances to cities, as the humans usually live inside of mountains or underground, to avoid the Zeharu.

As said, they usually live under the ground, but there are a few cities and towns above ground. Instead of netting or wiring, they use a sort of spear to shoot the Zeharu down. They would aim for the vents on a Zeharu, as they are a Zeharu's weakpoint.

Once this specialized spear impales the Zeharu, a mechanism goes off, near the tip of the spear, four spikes will come out from it. Wedging the weapon in the Zeharu and it's incredibly hard for the Zeharu to remove one without it causing serious damage.

It took the humans years to figure out how to improve their accuracy with these weapons and how to fire them faster, magic was the key! They ended up finding green gemstones, at first, these gems were thought of as useless. But one time a human used it to make a sword, once he got the blade coated in a creature's blood, whenever he threw the blade, he found it almost always hit its target. Even if the aim was miles off, it would redirect itself, sort of like a boomerang. But it only redirected itself once, if it missed, it would just fall and clatter to the ground.

They learned to do many things with these gems, by taking a large gem and dividing it into pieces, they could make many moveable objects. For example, the slab Mathias is on, it's being controlled by the man with the staff, the lesser gems are drawn to reform with the others, so the slab will move and follow the staff (since it has more gems in it).

With a click of a button, the man can disable the staff and the slab will stop moving.

(And here is where my brain is shutting off xP

It's late... That's all for now~ So enjoy~)

Awwh, I'm sure the Zeharu are quite a nuisance to thehumans but seeing them all tied up still makes me sad :(

That's one dangerous net! I love the lore you've come up with for the threats that Zeharu encounter. Such a cool species and world!

oooh god both the net and spears sound very painful--

hmm id bet that earth zeharu are one of the more frightening kinds to humans since theyre a burrowing sort, right?
