Tick Bites – Warming Temperatures
Warmer temperatures may be causing blood-sucking ticks to shift their feeding preference from dogs to humans in a potentially growing threat to public health. This finding is alarming because ticks carry and can transmit deadly Rocky Mountain spotted fever.
Experiments conducted at the University of California, Davis School of Veterinary Medicine placed a human in one box and a dog in an adjacent one. The researchers watched at various temperatures as the ticks sniffed out which mammal would bring their next blood meal. While at 75 degrees Fahrenheit the ticks showed a distinct preference for the dog, they became 2.5 times more likely to prefer humans at around 100 degrees.
