The control measures to use are made more difficult at a large medical center where we have to rely on faculty and technician compliance to change clothes, and follow aseptic procedures in handling their animals. This is made more difficult by not having enough ventilated racks or microisolators to house all the rats and mice - so we have to allow conventional shoebox caging to continue. SPF or barrier maintained animals have higher per diems and many projects are not funded for that assurance of rodent health. First step is to prepare future budgets to house animals in ventilated racks or behind the SPF barrier. Two, keep animals from entering an environment that is possible contaminated with pinworm eggs.
Eggs die on their own after several weeks.
Our goal is to stop all the shedding. Any quat ammonia product can be used, or other ammonia cleaner can be used and is effective. The disinfectants used to routinely sanitize bench and counter surfaces are still the ones we should be routinely using. There is no need to bomb, fog, smog or otherwise blow-up the rooms. Eggs are best removed by good housekeeping practices.
