As well as size and capacity, shredders are classified according to the method they use; and the size and shape of the shreds they produce. 1  Strip-cut shredders use rotating knives to cut narrow strips as long as the original sheet of paper.
Thoroughly and regularly clean areas where you find adult fleas, flea larvae, and flea eggs. Vacuum floors, rugs, carpets, upholstered furniture, and crevices around baseboards and cabinets daily or every other day to remove flea eggs, larvae, and adults.
2) keep a paper thin layer of diatomaceous earth wherever a vacuum cannot reach. 3) vacuum once every three days, tossing a little diatomaceous earth on the floor first. 4) if you have a pet: flea comb every three days (every day if fleas are found)
