They are sand fleas I battled them for over a year ,,,Use a mosquitoe spray with deet on u and furnitrue in car and clothes b4 u wash them...put salt on ur floors carpet or hard floor..leave for 36 hrs..also salt ur bed ,,yes right on top of comforters and sheets and shake out b4 sleeping in it. I put salt on couches then vacumed and left under cushions till vacumong floors.. i rotated thevdeet and salt 3 times a week..Vacum Vacum Vacum...i have tital hardwood and thry came out of cracks for 3 weeks .U must take them out of ur skin ..Females go in 1st then males. Hard bitters 2nd. I used the deet spray a sterile needle amd sterike tweezers..also scrubbing ur skin in shower with baby wipes and lavender soap does help pull them out..they grip to the threads in baby wipes..best of luck!!
