Signs of Bed Bug Bites - Health Checks

Sharing buttons:


hi I'm dr. Jorge parada medical advisor

for the National Pest Management

Association today I'm going to talk

about bedbugs and what you should know

about the bites that this pest leaves

behind I often hear patients who think

they have been bitten by a bedbug and

want to know if they should be concerned

although bedbugs were once rare in the

United States they have made a comeback

and are now widespread throughout the

United States and the world so it is

important to know how these pests can

affect our health


bedbugs feed on the blood of humans and

other warm-blooded hosts they tend to be

most active at night because they are

attracted to the steady stream of carbon

dioxide we admit while we sleep bed bug

bites are painless because the bugs

inject an anticoagulant or blood thinner

along with an anesthetic to create a

numbing effect as they feed feeding

usually takes five to 10 minutes if you

are bitten by a bedbug

the most common thread is from the bite

itself which can turn into a large

raised itchy welt and if the welts are

scratched they can become infected

people are more likely to have an

exaggerated skin reaction if they are

repeatedly bitten because the skin

becomes sensitized to the bites


everyone reacts differently to bed bug


in fact as many as 30% of people do not

have any reaction at all and may not

even realize that they were bitten for

those people who do have a reaction the

bites can range from a tiny puncture

wound to large red raised Wealth's the

bites usually are noticed upon awakening

though in some cases the reaction may

take up to two weeks to develop bedbugs

are often lined up in a row on the skin

and are typically on exposed areas such

as the face neck hands legs or arms

these bites can take as long as three to

six weeks to fully heal if an

infestation is present new bites may

accumulate even as the older ones

disappear so there may be bike reactions

in various stages of evolution at the

same time progressive swelling warmth

tenderness and in rare cases fever may

be symptoms of secondary infection


bedbug bites

do not typically require treatment

pitching is by far the most common

complaint by those who experience bedbug


if itching becomes severe people will

find relief with topical steroid creams

or oral antihistamines clean the bite

sites with soap and water and avoid

scratching to prevent infection if a

secondary infection occurs consult your

physician so we can be managed with

antibiotics as appropriate bedbug bites

can look very similar to other insect

bites so it's important to see your

doctor to confirm if the bites are from

bedbugs or something else you can work

with the qualified pest professional to

confirm if an infestation is present in

your home thanks for watching this
