Live rat sightings are a sure sign that an infestation is in progress, but may not occur until an infestation has become severe. Instead, be alert for the signs of rodent infestation. Addressing infestations early will save you time, money, and effort.
Winter is adult Ixodes pacificus (western black-legged tick) season in California. Laboratory staff have begun surveillance of this tick and the disease-causing bacteria they carry in parks and open space throughout San Mateo County. Ticks are collected by dragging a 1 meter square white flannel flag over the vegetation alongside trails.
On December 2, San Mateo Mosquito and Vector Control District laboratory staff helped lead a field trip at Wunderlich County Park for Stanford students learning about tick borne diseases. The class was entitled Parasites and Pestilence and was led by professor and District Trustee Dr. Scott Smith. Students were given tick flags and instructed on basic tick biology as well as how to collect ticks and sort by sex and species.
