Yes, what is THIS bug?
Hello bugman,
Thank you for your wonderful site for people who want to find out what bug they found. I’ve been searching your site in the past month trying to identify the bug we encountered, but no success. After the caught bugs spent a few weeks in a container in the fridge, I was able to put them under a microscope and take some pictures. The last one was caught before it sucked blood. They are about the size of a pinhead, about 1/2 mm. See: http://www.vandeven.us/bug Click on the pics for enlargement. What do you think….? My friend thinks she got this bug while visiting a friend, countryside of Virginia. They were sitting outside in a two-seater swing with cushions that remain outside. They have lots of birds that they feed, and two outside cats. Something itched her ankles and they got up and left. She had a few bites in the two days, but by the time the week was over she had some 200 bites all over, mostly on her ankles, further on legs, waist, groin, and on her sides between armpit and waist. She found a few bugs, but not the 50 or 100 that you would think would cause all those bites. We thought they were chiggers or bedbugs, and we did all that was recommended to get rid of those. But now that I have seen them under the microscope, I see they are neither. They must be some mite, bird mites, maybe??? I hope you can help us resolve this mystery of “the week of 200 bites.”

Hi Bugman,
I wrote you earlier today about an unidentified bug. I kept searching and found Dr. Barry OConnor mentioned on your site. So I went ahead and sent him my pics and story. Below is his reply. I still don’t understand how my friend could have over 200 bites and find only 4 lone start ticks, but I do think Dr. OConnor is right about the tick. So maybe there was another coincidence that we just never will find out… Thanks, and all the best with your site!

Hi Lianne – Your photos are of larval ticks. Although the specimens are damaged, in your area, the most likely species to bite people in this stage is the “lone star tick”, Amblyomma americanum. These are very common in the eastern USA, and the bites are hard to prevent. The bites themselves are painless, but one can develop an allergic reaction after some time that would cause itching. One should do a “tick check” daily after walking in tick-infested areas and remove any that are found. The larvae, sometimes called “seed ticks” are small, but they should still be removed carefully to be sure the mouthparts are not left in the skin. You can’t really rule out chiggers as the cause of most of the bites, especially if they were very “itchy.” The pattern you described would be consistent with chiggers, which should be common as well in your area. Chiggers are quite a bit smaller than larval ticks, and their bite fairly quickly causes the “itchy” immune response. People tend to scratch off the actual chigger before they really get the itch, but by then the damage is done! Lone star ticks only have the “star” in the adult female stage; the white area seen in ventral view in these larvae is the excretory product, guanine, stored in the gut. I hope this helps! All the best! – Barry

Wow Lianne,
Thanks for the fabulous images, marvelous information, and expert opinion.

    I’m currently showing signs of late lymes disease after 5 months of coming back from india. I found a tick larva under my skin on my shin. 3 weeks after my return, I didn’t get it checked out. my home is infested with ticks as iv got a new dog who brought them into my home.
    Iv fumigated the home and bedding, but after I got all settled. Took a week to wash the contents of the home. I was laying in bed and feltsomething bite me. I know this could be the Lymes, but I still checked it out. Mag tourch in hand checking my bed. There are all these white dots, so I sit with parranioa watching, these things started to grow infront of my very eyes. so I sprayed the bed again. But I think its ticks and not fleas.. after spraying my bedding with virbic I gave it 2 hours and climbed into bed as it was 4am and this morning I’m covered in white lumps on my legs. I got a lump out of my foot that was niggling away and it was aa tiny lump, cant mak out what it was but I burnt it and it sprang up and then withered. wtfis going on. please help me. do you think I have eggs under my skin and if so what do I take orally to kill these things under my skin. desperate is not the word. x

    I am infested with ticks hand me down from my cat…this now for over 6 months… I seem to be a host to these paradites! I am taking Ivermectin pills to rid myself and it kills them but the eggs keep on coming…! I really don’t understand this…they need blood to reproduce…they dig into me they die…no eggs it should be…! Another thing…my ticks seem to fly or when I got to touch a live one it just vanished and I couldn’t see where it went…very fast and stealthy! Any suggestions on how to permanently rid myself of this infestation would be much appreciated
