Clindamycin causes Clostridium difficile associated diarrhea (CDAD) because it can alter the normal bacteria in the colon and encourage overgrowth Clostridium difficile, a bacteria which causes inflammation of the colon (pseudomembranous colitis).
In some cases follow up treatments may be necessary to eliminate any eggs that were not hatched before initial treatment or not exposed to the chemical during treatment. If bed bugs are still visible and active 3 weeks after treatment, a follow-up treatment may be necessary to fully eliminate the infestation.
Depending on the temperature, it takes nymphs about 100 days for the five molts to occur before mating can take place. Roughly 1.5-2 months are required for a complete cycle from egg to mated adult bed bug. Adult bed bugs live about 10 months, although without a host, bed bugs may live over a year. Bed bug infestations develop slowly. At first very few insects are present, feeding intermittently on the host and may not be noticed. Bites are sometimes overlooked or blamed on some other pest species like spiders.
