Grasshoppers indoors

hey guys this is my first grow. i am growing indoors in dirt under a 400w MH a while back i noticed a few little bugs on my plants used an online identification guide and it turns out they are unmature grasshoppers. probably about 1/4 of a inch long. how does one get rid of this pest. so fat it doesnt look like they are harming my babies but i dont want to take any chances.

thanks for any help
