Tenants at Pequonnick Towers complained Thursday that their public housing units are infested with rodents and are plagued by other safety issues.Mice routinely squeeze their way between drainpipes and cracks in the apartments, say tenants. Calishanae Dempsey lives at the towers and says she can see mice playing in a hole where her dishwasher is supposed to be. Meanwhile, other residents have found mice feces in their babies? cribs.In addition to the mice infestation, tenants complain ledges are exposed because of holes in fences, causing one child to recently fall and break his leg. Heating is yet another problem. When cold weather rolls around, residents say they have to turn on their stoves to warm their apartments.The Bridgeport Housing Authority is giving out glue traps to those concerned about rodents, but some residents say the housing authority?s effort to address their complaints is not enough.
