Transcript Bedbug Information and Guidelines

Bedbug Information and Guidance
Bedbugs bite exposed skin of sleeping humans to feed on their
blood. Decades ago, bedbugs were eradicated from most
developed nations using DDT — a pesticide that has been
banned due to it’s toxicity. The risk of encountering bedbugs
increases if you spend time in places with high turnover rates of
nighttime guests — such as hotels/motels, hospitals, homeless
shelters, or other group living environments.
Bedbugs are reddish brown, oval and flat, about the size of an
apple seed. During the day, they hide in the cracks and crevices
of beds, box springs, headboards and bed frames. If you have
bedbugs in your home or healthcare organization, professional
extermination is recommended.
Bedbug Information and Guidance
It can be difficult to distinguish bedbug bites from other insect bites. In general,
bedbug bites frequently are:
 Red, often with a darker red spot in the middle
 Itchy
 Arranged in a rough line or in a cluster
 Located on the face, neck, arms and hands
 Some people do not have reactions to bedbug bites, while others may experience an
allergic reaction, which may include severe itching, blisters, or urticaria.
What can the patient do?

Prepare a list that includes:
A detailed description of symptoms
History of recent travel
History of recent hotel/motel/shelter stays
All medications and supplements being taken
If bedbugs are suspected, immediately notify the healthcare team of the source and
inspect the facility. The patients must also inspect their homes, mattresses,
furniture, and bedding brought to the facility for the insects. This inspection may
need to be conducted at night when bedbugs are active.
Bedbug Information and Guidance
Potential treatments for bites. The itchy red spots associated with bedbug bites usually disappear on
their own within a week or two. A patient’s speedy recovery may be enhanced by the application
of:
 A skin cream containing hydrocortisone
 An oral antihistamine, such as diphenhydramine (Benadryl)
 If you develop a skin infection from scratching bedbug bites, the doctor may want to prescribe an
antibiotic.
 The resurgence of bedbugs in developed countries may be linked to:
 Increased International travel
 Changes in pest control practices
 Insecticide resistance
Where do bedbugs hide? During the day, bedbugs hide in the cracks and crevices of:
 Mattresses Box springs
 Bed frames
 Headboards
 Under peeling paint and loose wallpaper
 Under carpeting near baseboards
 Upholstered furniture seams
 Under light switch plates or electrical outlets
Bedbug Information and Guidance
How do they spread?


Bedbugs do not usually stay on their human hosts after their meal, but they might take
refuge and travel in the seams and folds of luggage, overnight bags, folded clothes,
bedding, furniture, and anywhere else they can hide. Most people do not realize they can
transport stow-away bedbugs potentially infesting new areas. If you travel or frequent
group living environments, bedbugs could get into your luggage and/or bags and you
may be providing passage for these insects to uninfested areas.
While bedbugs may hitchhike on a persons belongings, they can also crawl about as fast
as a ladybug. So they can easily travel between floors and rooms in hotels/motels, group
living conditions or any place where bedding may be present.
Preventing Infestations


Inspect secondhand items such as used mattresses, upholstered furniture, and bedding
carefully before bringing into your home and potentially cross infesting the dialysis facility.
Hotel/Motel/Shelter or Group Living precautions. Check mattress seams for bedbug
excrement and place luggage or bags on tables or dressers instead of on the floor.
Bedbug Information and Guidance
Sign of uncleanliness?

Bedbugs do not care if their environment is clean or dirty. All they need is a warm
host and plenty of hiding places. Even pristine homes and group living
environments can harbor bedbugs.
 Bedbugs are more common in crowded living environments that experience high
turnover in occupancy, such as:
 Apartment complexes
 Dormitories
 Homeless shelters
 Hotels/Motels
Most bedbug bites require no medical treatment. You may want to consult the physician
if you suspect an allergic reaction or develop a skin infection after scratching the
bites.
Bedbug Information and Guidance
Look for these signs:


Dark specks. Typically found along mattress seams, these specks are bedbug excrement.
Empty exoskeletons. Bedbugs molt five times before becoming adults. These empty skins are
light brown.
 Bloody smears. You may find small smears of blood on the sheets where you accidentally
crushed an engorged bedbug.
 Treating your Home and/or Healthcare Facility. Once the patients immediate symptoms
are treated; the underlying origin must be identified and treated professionally to eradicate
and prevent cross infestation. This may include a combination of pesticides and nonchemical
treatments.
Nonchemical treatments may include:
 Vacuuming. A thorough vacuuming of cracks and crevices can physically remove bedbugs
from an area. But vacuum cleaners cannot reach all hiding places.
 Hot water. Washing clothes and other items (bedding) in water at least 120 F (49 C) can kill
bedbugs.
 Clothes dryer. Placing wet or dry items in a clothes dryer set at medium to high heat for 20
minutes will kill bedbugs and their eggs.
 Freezing. Bedbugs are also vulnerable to temperatures below 32 F (0 C), but you would need
to leave the items outdoors or in the freezer for several days.
Bedbug Information and Guidance
Some professional exterminators use portable devices to raise the temperature of a room to a
lethal temperature. All stages of bedbugs can be killed at 122 F (50 C). In some cases, you
may have to throw out heavily infested items such as mattresses or couches.
