It is spring and the flowers, black flies and ticks are blooming! Flowers and black flies rarely cause significant health problems, but deer ticks can. They can transmit Lyme disease by transmitting Lyme bacteria when they attach to their victim. They can also transmit the rarer diseases called ehrlichiosis, babesiosis and, even more rarely, tularemia and Lyme variants, recently reported to cause a dementing illness especially in the elderly. Our region used to be on the edge of the deer tick/Lyme disease infestation area, which was the southern New England states and southern Maine.
