Answer: Permethrin
I do not believe in this whole Lyme’s syndrome/ chronic illness hypothesis. I live in tick country, can’t go outside without getting a dozen. Everyone in my family tests positive for Lyme’s, as I would guess does everyone in the rural parts of the county in which I live. Only one person I know ever had symptoms, which are pretty generic and could be attributed to many other potential causes. Likewise with our dogs, all that have been tested have postive antibodies to Lyme’s, only one ever had symptoms, which could have other causes. If there is something to this, it must be a very small sub-population that has a strong susceptability to this disease process that the majority of us do not share. Doctors and veternarians I have spoken to about this agreed; two of the doctors went so far as to say it is psychosomatic/mental illness— they believe real Lyme’s has always been easily and quickly treatable with a single course of anti-biotics and people who have lingering symptoms are delusional.
The Blacklegged tick is found in wooded areas, especially if deer are present and has to be attached to you for at least 36 hours to spread the disease.I wouldn't want to take my chances with the clock too many times, but it's good to know there might be a window of time and hope if you find a tick on you or a loved one.
That link also has a large picture of what the rash looks like and might be helpful if you suspect an infection.
“Those infected can develop severe, rheumatoid arthritis-like joint and muscle pain. Fatigue and neurological disorders — such as numbness, tingling, weakness, and cognitive impairment — can set in too.”
Some of us wouldnt notice the difference.
