Entomological warfare

Entomological warfare is when people use bugs (like mosquitos or beetles) as weapons in a war. The bugs are trained or altered to carry diseases or chemicals that can harm or even kill the enemy's soldiers or people. This kind of warfare was used a lot in the past, but now it's illegal because it can cause a lot of harm to innocent people and the environment. Think of it like playing a game, but instead of using toy soldiers, people used bugs to try to win. But it's not a very nice or fair way to play the game, so we don't allow it anymore.
