During peak tick season, October-April, our staff collects ticks at designated tick surveillance sites in the foothills. We identify the different species of ticks found and test for tick-borne diseases like Lyme disease. The table below includes the most up to date tick surveillance data from the District although ticks are active year-round. It’s important to always take precautions when entering a tick-infested area.
- DEFEND yourself from ticks with an EPA-registered tick repellent.
- DRESS PROTECTIVELY by covering exposed skin with clothing, wearing long pants and sleeves, and tucking pant legs into socks.
- DISCOURAGE ticks from around your home by clearing debris and dense vegetation.
- DO regular tick checks for several days after being in tick habitat and shower or bathe as soon as possible after being in a tick habitat.
- DETACH ticks immediately using the proper technique.
