Don’t Let Dermacentor Ticks Make You Sick

It’s summer and that means peak season for the dog tick and Pacific coast tick (collectively called Dermacentor ticks)! These large, brown-colored ticks are very prevalent this time of year along the edge of trails and in brushy areas with tall grass all throughout California. Unfed, they can be nearly three times as large as the black-legged ticks that are prevalent during the winter and spring and can engorge to the size of a grape if left attached to repletion.

Flea Circus is No Fun for Pets or People

Most people have had an encounter with a flea at some point – the jumping black specks, the small itchy bumps they leave in their wake, and the general feeling of unease due to having a parasite in your home. However, few people understand the biology of fleas and why they invade our homes in the first place.

Urban Carnivores
Learning to Live Together

Coyotes

You may have heard their cries at dusk. Coyotes are one of the most common urban carnivores in San Mateo County and important predators of rodents. Coyotes also help control deer and Canada geese, which can be very destructive to gardens and grassy areas, by preying on their young and slowing their population growth. There is also evidence that coyotes may directly compete with raccoons, skunks and opossums which helps to reduce the numbers of these urban carnivores as well. That being said, coyotes can be a challenge to live with.

During February, rodents made the news in a big way in California. However, these weren’t the familiar rats and mice that plague homeowners. Invasive nutria, native to South America, had been reported in California for the first time since the 1970s.

Mosquito-Proofing Your Spring Break

T-shirts, keychains, and new friendships make great spring break souvenirs, but how about dengue, chikungunya, Zika, and yellow fever? Getting sick on vacation is bad enough, but travelers face an even scarier prospect – bringing mosquito-borne illnesses back into their communities.

Coyotes Cause Concern

As coyotes become an increasingly common sight in urban and suburban neighborhoods, some residents have become concerned. Although coyotes are naturally shy and elusive, they’re also smart. Individual coyotes can learn by experience, and unfortunately the lessons many residents are teaching them are ones that will get them into trouble.

Don’t Take Chances with Rabies

Human rabies infections in the United States are exceptionally rare. However, in January a Florida 6-year-old died of the virus after exposure to a sick bat. According to news stories, his family was not aware of the risk of rabies.

Enjoying the Warm Weather? So Are the Mosquitoes

Have you ever wondered why you don’t see many cold blooded animals, like reptiles or insects, in frozen regions of the world? Heat allows animals to run, jump, and think and mosquitoes are no exception. The warmer the temperature (up to a point), the more aggressive and hungry they get. They also reproduce much faster which means that surges in temperature can mean big surges in mosquito numbers.
