Larva are ferocious meat-eaters that dine on many other noxious wood-boring larvae, including those of wood-boring beetles. This species spends most of its life in the larval form, perhaps as long as 2-5 years. All the longer to do its good deeds! If at all possible, just try and relocate the beetle to an area where you are both comfortable with the distance between you -- say the beetle outside and you inside -- this way the beetle will be able to procreate and continue the cycle of keeping the bad guys away!
