In Revelation it talks about locusts coming out of the bottomless pit at some point and leaving the grass and trees alone, but tormenting men. This is not normal behavior for locusts, normal locusts don't attack people, but chew up all the grass and plants in their path. In Revelation these are demonic creatures sent to torment people that have taken the mark of the beast. I have heard a theory that I agree with, is that it will be some sort of bio-chip that yes indeed gives you access to economic activity, but also may change your DNA to turn you into a gibborim. In most modern bibles it is vague concerning this kind of thing happening to Nimrod, but in the Greek Septuagint it says "he BEGAN to BECOME a GIANT", so Nimrod was at first a regular human being, then some other genetic material was added to him that turned him into a gibborim after the pattern of the ancient giants before the flood, that were the products of fallen angels and human women mating. Most or all of these creatures are unredeemable, and at least for the msot part it is God's will for them to just be killed. The tribes that God told the ancient Israelites to kill entirely with no mercy were made up of these giants and other hybrid creatures.
The people who take the mark of the beast and have this happen to them do so fully of their own free volition, and thus after that point are pre-damned with no hope of repentance, and are destined to burn forever in hell. Part of their punishment on this earth is to be tormented by these human attacking, grass sparing locusts. Part of my concern is noticing a growing apostasy in the Evangelical churches to the point where many Evangelicals will be fully capable of taking the mark of the beast when he shows up. When you see an apostate Evangelical church, RUN away fast, even if they stamp the "we are bible-believer" stamp on top of various forms of wretched apostasy. They need to repent. Where do people turn when the places that are supposed to provide spiritual sanctuary become open portals to hell? The people of God should re-organize on better terms, and turn away from apostate churches and never respect the "authority" of apostate pastors and church leaders.
