Neither common <br />house mice 1I0r common rats have been associated with HPS ill humans, <br />for example. Yet because it can bc tough to tell just what kind 01' rodents <br />you have, play it safe -- dean up the infestation and rodent-proof your <br />home or workplace. <br /> <br />Here arc some common signs that you may have a rodent problem. <br /> <br />Rodent Droppings <br /> <br /> <br />This is one of the most reliable signs <br />that you have a rodent problem. You <br />may find droppings in places where <br />you store your food or your pet/animal <br />food, such as in cupboards and drawers <br />or in bins. Bccause mice like to run in <br />places that offer them some protection <br />from predators, you may find <br />droppings in cupboards or under the <br />sink, along walls, or on top of wall <br />studs or beams. Mice will leave droppings near their nests as well (see below). <br />Storage rooms, sheds, barns, or cabins loaded with boxes, bags, old furniture, <br />and other objects make an ideal home for rodents, so you may find droppings <br />there, even inside boxes and other containers. <br /> <br />Workplaces can also makc good rodcnt homes. Warehouses, restaurants, and <br />the like are obvious placcs to look bccause food may bc plentiful there. <br />However, rodents can infest officc buildings, too. Once again, look for <br />droppings in protccted places, such as closets, storage rooms, or inside boxes. <br /> <br />Signs ol'Rodcnt Nests <br /> <br />Rodents tend to build their nests from materials that are soft, fuzzy, or warm. <br />Among common rodent nest materials are shredded paper, bunches of dry !,'Tass <br />or small twigs, fablic, and furniture stuffing_ Rodents will nest wherever safety <br />from enemies can be found close enough to food and water, and thcy prefer <br />places that arc relatively quiet Inside buildings, hcre are somc places to look: <br />p;"-" <br /> <br />. insIde <br /> <br /> <br />http://v..'Ww.cdc,gov/ncidod/discascs/hanfa/hps/noframes/prev en t8, h tm <br /> <br />1 1/18/2005 <br />
