Size: Unlike other pests, such as a roach or a mouse, bed bugs are extremely small. Due to their size, they can be difficult to spot. A tenant may not know he or she has a problem with bed bugs until the infestation has spread.
Lifespan: An interesting fact about bed bugs is that they can feast on blood and can then survive an entire year without another meal. This is one of the reasons it can be so difficult to get rid of them.
Mobile: Since bed bugs are so tiny, they are difficult to spot. They can easily climb into a purse or onto clothing and be brought back to a home without being seen.
Indistinct Bites: People react differently to bed bug bites. Some people have no reaction when bitten, while others quickly develop red welts. Even in those that develop the red welts, it can be hard to distinguish the bite from the bites of other insects, such as a mosquito or spider.
Ineffective Treatment: Bug bombs are usually not the best way to treat a bed bug infestation. It often causes bugs to spread out. In addition to not using the proper treatments to kill the bugs, many landlords and tenants do not follow the proper steps to keep them from spreading. Tenants should wash all fabric in the hottest setting possible and vacuum frequently, while landlords should never let new tenants move into a unit with a known infestation.
