The Nature of the Bed Bug

How to Identify a Bed Bug

How to Treat Bed Bug Infestations

How to Educate People about Bed Bugs

BED BUG HISTORYHas always been an issue

Virtually eliminated in US

Rising numbers since 2001

Skyrocketed in last 5 years

EPA held 1st ever Bed Bug Summit

THEYRE BACK BUT WHY?Increased international travel

Change in general pest control methods

Reduced available products for control

Lack of research and developmentTRAVEL

BON VOYAGE

BED BUG BASICSFeed only on blood

Feeding lasts 3 12 minutes

Nocturnal

Can detect and avoid chemicals

Cryptic

Crawl up to 20 feet to feed

JUST A LITTLE GUY

LIFE CYCLE

I lay between 1 and 5 eggs every day!Starting as an egg, it takes me 30 days to become an adult!Ill molt 5 times before I become an adult!Ill live about 10 months and lay between 300 and 500 eggs!I may live up to a year without feeding

HOW DO YOU KNOW IF YOU HAVE BED BUGS?Check your linensLook for movementLook at the insectColor? Size?Does it have wings?Is it flat and oval?Inspect at night

* Check your bed linens in the middle of the night, when bed bugs are most active and easiest to locate

* See movement? Bed Bugs usually travel in groups of two or three in a row

Look at the insects bodies. Immature bed bugs are a light yellow color; adults are a reddish brown. In both cases, the middle part of their bodies will be darker after they have recently fed

* Not sure based on the color of the insect? Look at their size: bed bugs are smaller than of an inch long

*Still not entirely certain? Determine whether the bug has wings or not (bed bugs do not); look at its shape (bed bugs are oval and flat in shape)

* Looking for bed bugs during the day can prove to be an exercise in futility: during the days, bed bugs hide in cracks and crevices in the walls and in your mattress

Seams of mattress

Many bites !!!!PENN STATES RESPONSE STRATEGY

Isolate students and their belongings in the roomPest Control responds immediately to inspect and treatClothing and bedding treated in dryerMattresses are removed, to be replaced after treatmentStudents are relocated if possible

Once a report is received isolate the students and their personal belongings in their room to avoid transferring bedbugs within the building or within the community. Get the Pest Control company on site immediately to verify, educate the students, and treat as appropriate. Education addresses the entomology of bedbugs including such things as the life cycle, treatment, health implications, etc. Education also includes students in adjacent rooms and appropriate inspections and preventative treatments as necessary. The students clothing is run through the clothes dryers on high heat for 30 minutes to help eliminate any hiding population. Bedding should be run through dryer separately. Do not overload dryer so as to allow even heat. Mattress are removed and replaced after treatment Suggest to the student that they visit the health center for any appropriate treatment. This is a precautionary step meant to reassure students and parents. According to the Mayo Clinic web site, treatment of bedbug bites usually involves steps the effected person can take on their own, but in more severe cases they may need to see their doctor. To date, bedbugs aren't known to spread disease to humans. Bedbug bites are similar to mosquito bites in that they inject an anticoagulant to keep the hosts blood flowing as they suck, along with an anesthetic agent to keep the host from feeling them when they're at work. Life cycle implications once treatment has occurred we will not know for 4 to 6 weeks if all bedbugs were destroyed. Due to this we relocate students to another room if possible so we can quarantine the effected space and continue to treat the room as necessary. If possible the effected room is not used again until we are confident eradication in that space has occurred. 24VACUUM THE CARPETThoroughly vacuum the carpet areas

Can occur before or after the heat treatment

Dispose of the vacuum bag

25STEAM TREATMENTPull the carpet back from baseboards

Steam along all edges at the junction of carpet and wall

26RESIDUAL APPLICATIONApply residual insecticide along junction of wall and floor

Apply dust behind all wall plates

30HEAT CHAMBER

31Fans and heaters are placed in opposite corners of box

Thermometers are placed in most insulated places

Oscillating fans prevents heat stratification

Items designed to resist heat change are hard to heat up; sleeping bags, comforters, down jackets

So, whats the problem?

Bedbugs freak people out!We know a lot about these critters, and we have treatment options that work. Why are bedbugs such a big deal?

How many of you are itching and scratching right now just from this presentation? Imagine waking up to find even one of these pesky buggers on your arm or your leg. Imagine seeing their fecal matter and skins on your 500 count periwinkle blue sheets. When students find bedbugs in their room, its a traumatic experience and thats why dealing with the people involved in a bedbug incident can be the most difficult part.33BE PREPAREDWho will respond?When will the call come?How will you treat the room?Where will your resident stay?What are you going to say??The best time to develop a bedbug plan is BEFORE you ever see a bedbug.

Who will respond? What are the chances that the first person a student tells about the problem shes been having is her RA or housekeeper? Pretty good, right? If that happens, does the RA or housekeeper know what to say or do? Part of your plan should be making sure everyone knows what the plan is and what their part is in it.

When will the call come in? If a student calls in the middle of the night, how will that affect the way you respond? Will you begin inspection and treatment right away? Will you wait? Once youve begun treatment, whats your timeline? When will you inspect and retreat? If youve moved the students, when can they return to their room?

How will the inspection be conducted? When you find a bedbug, how will you treat the infestation? Does your pest control team use steam, pesticides, heat, or a combination of these? Know and understand what will occur in that room so you can be part of the solution.

Where will the student live? Will they stay in the room? Do you have a temporary room for them? What happens if you have multiple events at one time? Do you have enough temporary rooms? What happens if they cant move?

What information will you give the students and parents? Have a handout ready. Give them the information they need to feel in control of the situation info about the bug, the steps youll be taking to eliminate the problem, what they can do to help.

34You can run, but you cant hideBe proactive

Educate

Be a partner

Given the current bedbug situation, if you havent already experienced bedbugs at your campus, you will. Be proactive.

Educate your students. (Distribute poster) Give them the tools they need to prevent bedbug infestations. Include a blurb in the newspaper or newsletter before they leave for breaks: encourage them to check their hotel rooms and take preventive measures such as leaving their luggage in their trunk and drying their clothes in high heat.

Be prepared for the brief flurry of panic there will be false alarms, media attention, and questions. However, once you get through the initial firestorm, your residents will actually feel MORE comfortable because they have the information they need to feel in control of the situation.

At the start and end of semesters, remind students not to take furniture mattresses, chairs, sofas from unknown sources. That new-looking mattress by the curb might just come with a few surprises.

Partner with your community to prevent the spread of bedbugs. Work with off-campus apartments by sharing information and encouraging an educational approach.35BED BUG WEB SITESMike Potter University of Kentucky - http://www.uky.edu/Ag/Entomology/entfacts/struct/ef636.htm
