mine was these roach gel baits when we had an infestation of tiny cockroaches (around 12-15 mm in size)
just apply a pea size every 2 ft where light cant get them (and your pets), cover or hide any other food sources like trash or table scraps them bam! you’ll be sweeping swarms of dead roaches several days after.
then repeat application every 6 months
maybe it lacks some stuff…like a pointy hood thingy
