MRSA is a dangerous bacteria usually acquired from hospital visits. It often happens when a person has a cut or bite, such as those you might find from bed bugs. It’s not the bite itself that causes the problem, it’s scratching the bite and causing an infection that brings you to the hospital and eventually in contact with the MRSA Virus (although not really a virus, it’s a strain of bacteria Staphylococcus aureus).

When you catch MRSA and have not been in a hospital, such as a bed bug infested apartment complex, it’s called Community Associated MRSA or CA-MRSA for short.

What makes this bacteria so dangerous is its resistance to oxacillin, penicillin and amoxicillin and other antibiotics. This is how a few simple bed bug bites can turn into MRSA as in the picture below.

You can see that the bites started small, then the hand started to swell, then blisters and eventually the underlying skin begins to deteriorate; another bite that is prime for MRSA looks like the one on Lisa’s face below:

The best treatment is preventative – when you have a bite from bed bugs or similar pests, make sure you keep the area clean, use an antibiotic ointments or gel and monitor the bite frequently to prevent infection and a hospital visit.

Hi. My wife and I travel to Mexico a year ago, we stayed there for two days at a not too nice hotel.both of us got several bed bug bites. my wife healed in about 2 or 3 weeks but I still have the condition but looks very bad, the itch is worst than when new. my doctor prescribed different kind of mouth taken antibiotics but nothing works.
I’m a desperate now.

Ju Mitchell::

Hi, the same thing happened to me where bed bug bites turned into mrsa boils. Ask the doc to swab the spots and send for analysis.

I was on many different antibiotics before any swab was taken – you have to ask for it to be taken. Its really frustrating that for a long time I was being treated for staff and not the mrsa, when a swab would have indicated the correct medicine that was required.

All the best.


My husband and I went to Fort Myers last year a year later I went to Mexico and I became very ill. I went to have a blood work where they did the Weil-Felix test. Please can you tell me what is this. Thanks

I’m not a doctor, but I believe the Weil-Felix test looks for rickettsia (carried by ticks, fleas and lice causing disease). If the test react with OX19, it would indicate a bacterial infection. I’d verify this with your doctor…


A few years ago I stayed in a Mariott Hotel near the Los Angeles Airport. I got 26 bed bug bites. We were on our way to Hawaii so I didn’t see any doctor and I never did get boils. However, after returning from our holiday, I began getting extremely tired. I was diagnosed with a rare disease, sarcoidosis which some Swedish doctors think is caused by rickettsia, which is carried by ticks, lice and other pests. I wonder now if the sarcoidosis could have been triggered by the bed bugs?
Any thoughts?
Best regards,

Bed Bug infestation @ hotel………. Size of ticks, husband had over 125 bites over his bald head, arms swelled up,bites every where face, neck arms and torso legs, and he continued to work, apon coming home i could not believe my eyes or the condition he was in…He went for medical aid. Currently going through an investigation process, as My doctor instructed me to remove carper anything cloth boil it or discard it…My bedding all destroyed from boiling. My carpet couch and bed all to the dump……. This has been a true hardship on my family. As my husband travels to support our family. He has bug phobia over this and so do I ….. I am outraged that this has happened and not enough is being done to control this. I have ANOTHER doctor appt tomorrow as i have spiked fevers, blisters on my tongue and feel terrible……..When you go through something like this your victimized by the control of other people. I believe this is turning into MRSA……..Tomorrow i will have a result.

I had 3 rounds of antibiotics to kill an infection on my scalp, face and ear……finally the doctor did a “swab” and tested it and sure enough it was MRSA, NO DOUBT in my mind now that i have bedbugs and that’s where the MRSA came from.


I got MRSA from shaking hands with a fellow employee whose body was covered in mrsa boils, covered by clothing – doctor was a general practitioner – but i went to specialists first, thinking it wasn’t his expertise, he knew immediately and prescribed Bactriban – ointment that u put in your nose coupla times a day – everything went away within two days and never came back. But my 2 yr old daughter now has 4 bright red bumps on knees, where she’d had dry skin for a long time, we had bed bugs last summer, got treatment, but i didn’t think they were all gone. They were isolated, so we thought, to only my sons room as i was never bit. Baby now with these bumps has had sporadic fever for 3 days, and no appetite. Just wanted to let y’all know that the Bacriban WORKS – and also, if anyone knows if this is what it sounds like.


I spent 7 days in the hospital from Mrsa, I have been fighting a bug of some type here and it has caused me to loose almost all I own the house may be next. They have gotten into every building. The doctors for two weeks tried to tell me it was my nerves sent me home with salve and Valium then I saw something stuff on my little dogs forehead.

I went back to the doctor and said now tell me this is still my nerves if you go out and see my dog no way my nerves are stuck on my dogs head. he even had on that stuff you rub on their backs. We are still in the middle of washing what we can and throwing.

Someone in Washington needs to get off their butts and get all this under control that is what they make the big bucks for. Why sit back and watch our USA go to the dump ground.
