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.
An individual bed bug can lay 200 to 250 eggs in her lifetime. The eggs hatch in about 6 to 10 days and the newly emerged bed bug nymphs seek a blood meal. Immature nymphs molt five times (they shed their outer exoskeleton in order to grow) before reaching adulthood.
