    Default Veggie/mineral oil and SHB

    Anyone know the action of the oil on the SHB? is it clogging up breathing pores and drowning them? is it simply immobilizing them? - Mike

    Basically, yes, it drowns them. Insects breathe through spiracles, openings in their thorax and abdomen. Air passively moves into the body through a tracheal system. The oil clogs this up and doesn't allow oxygen in.
