  • Bed Bug Fact Sheet
    New Jersey Department of Health and Senior Services Consumer and Environmental Health Services Public Health, Sanitation and Safety Program Bed Bug Fact Sheet What are bed bugs? Bed bugs are small insects that feed on the blood of mammals and birds. Adult bed bugs are oval, wingless and rusty red colored, and have flat bodies, antennae and small eyes. They are visible to the naked eye, but often hide in cracks and crevices. When bed bugs feed, their bodies swell and become a brighter red. In homes, bed bugs feed primarily on the blood of humans, usually at night when people are sleeping. What does a bed bug bite feel and look like? Typically, the bite is painless and rarely awakens a sleeping person. However, it can produce large, itchy welts on the skin. Welts from bed bug bites do not have a red spot in the center – those welts are more characteristic of flea bites. Are bed bugs dangerous? Although bed bugs may be a nuisance to people, they are not known to spread disease. They are known to cause allergic reactions from their saliva in sensitive people. How long do bed bugs live? The typical life span of a bed bug is about 10 months. They can survive for weeks to months without feeding. How does a home become infested with bed bugs? In most cases, bed bugs are transported from infested areas to non-infested areas when they cling onto someone’s clothing, or crawl into luggage, furniture or bedding that is then brought into homes. How do I know if my home is infested with bed bugs? If you have bed bugs, you may also notice itchy welts on you or your family member’s skin.

  • Bed Bug Fact Sheet
    BED BUGS September 2011 Bed bugs are found worldwide. In recent years, bed bugs have been making a comeback because of changing insect control practices, pesticide resistance and increased international travel. Travel spreads them because the bugs and their eggs are easily transported in luggage, clothing, bedding, and furniture. Quick facts o Bed bugs are fast moving insects that eat mostly at night when their host is asleep. o Prefer human blood but will feed on chickens, mice, and rabbits, too. o They feed on any area of exposed skin, such as the face, neck, shoulders, arms or hands. o The bites don’t hurt, so the person usually doesn’t know that he/she has been bitten, but bed bug bites do irritate the skin. o Depending on availability of food and temperature (70-82F is optimal); it takes 5 weeks to 4 months for the maturation of a bed bug from egg to adult. o They can go 80 to 140 days without a meal. o Adults live about 10 months. Do bed bugs spread disease? o Bed bugs are not known to transmit disease; however, they can cause physical and mental stress. o A reaction to the bites can take 1– 14 days to develop, and some people have no reaction. o Bed bug bites look like mosquito, flea, and spider bites. The only way to confirm the bite is from a bed bug is to find evidence of the bugs in your bed/bedroom. What do bed bugs look like? o Adult bed bugs are oval shaped, wingless, 1/3 inch long, rusty red or mahogany color, and shaped like an apple seed.

  • Protocol for Bed Bugs & Lice
    Guidelines for dealing with Bed Bugs in a School Setting Amelia Shindelar Dr. Stephen A. Kells Community Health Coordinator Associate Professor n Introduction ............................................................................................................................................................................ 2 Responding to Bed Bugs in Schools ........................................................................................................................................ 2 Bed Bugs in the school ............................................................................................................................................................ 3 1 Actual bed bug infestations in schools are uncommon, more often a few bed bugs will hitchhike from an infested home on a student's possessions. On the occasion that an infestation starts, it will be because bed bugs have found a site where people rest or sit for a time. A common example of this is with the younger grades, or pre-school, where rest time or nap time still occurs. It is important to remain vigilant for bed bugs in the school. Treating a bed bug infestation is very difficult and costly. The sooner an infestation is detected the easier it will be to control the infestation. Also, there are steps that can be taken to prevent future infestations. 'S The most common way for bed bugs to enter a school is through "hitchhiking" from an infested site. Usually this will be from a student, staff or teacher's home which has a bed bug infestation. While teachers and staff can be more easily addressed dealing with students or parents can be challenging, especially if the family cannot afford proper control measures or their landlord refuses to properly treat their home. Students dealing with a bed bug infestation in their home may show signs of bites. Different people react differently to bed bug bites, some people do not react at all and others have severe allergic reactions.

The second nap begins about 2-3 hrs. after the first nap ends but often no earlier than 11 a.m. The third nap starts between 3:30-5:30 p.m. after your child has been awake at least two hrs. Around 8 months, your child gradually transitions to two naps a day. 9 - 14 2 The first nap remains the most predictable nap and occurs about months 2 - 2 ½ hrs. after the regular morning rise time, most often 9 to 9:30 a.m. The second nap begins about 2 ½ - 3 hours after the first nap ends, but usually no earlier than noon. The naps together total about 2 - 4 hours. 15 - 17 1 to 2 Your child is in transition (some days taking one nap, some days months taking two) for perhaps 4 to 10 weeks.
