There is no season for the Deer tick. Once the female is fertilize it will
crawl up onto a branch and will go into a state of suspended animation
until it senses the oder of a passing animal. It will release and fall onto
the deer or dog or whatever. Once the tick draws blood the fertilized
eggs will start to grow. This cycle can take years. The tick can literally hang on a branch for years waiting on a target. The release from the
branch can occur in summer, winter, snow, or rain.
