See the garden center or hardware store, pick up some Buhach powder, it kills most bug's on contact, its wonderfull stuff, Ive used Buhach smudges in the summer on hornets nest's when im doing maintenance.
Dust some in yer carpet in the area of the beetles
Buhach is refined product of the pyrinthian flower pettals, this yellowish powder kills barn flies, fleas, black flies, aphids, tater bugs, dust some on yer dog's head round ther eyes(not in em) the skeeters leave them be
Dust it on yer chickens to kill chicken lice.
to make a smuge pour some in a heap in a tuna can and lite it off, it will burn slowly makeing a smoke that kills bugs / drives them away.
shake some in a window sill the flies hit that powder they die in less than 1/2 hr
So far it hasent seemd to harm warmblooded critters.
