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.
Fleas can lay 20 to 40 eggs per day, and 10 female fleas can create almost a quarter of a million different life stages in a month. Newly emerged flea larvae can survive two weeks without a blood meal, and pre-emerged fleas (pupae/cocoon stage) can survive six months without feeding.
