May is Lyme Disease Awareness Month!

Lyme Disease, Tick Surveillance and Awareness:
Be “tick-aware” of your surroundings when you are visiting our local parks and recreation areas! Lyme disease is the most reported vector-borne disease in the U.S., and in 2018 there were 33,666 cases in the US, while West Nile Virus cases totaled 2,647. Researchers suggest that the Lyme disease cases are nearly 10 times the reported numbers, due to under-reporting, or over 300,000 cases annually. While hiking in known tick habitat, consider using a DEET based repellent on your exposed skin, and an occasional tick check of yourself, your pets and companions will help reduce your risk of exposure to ticks. We can help with tick identification, risk assessment and help facilitate the submission of ticks for lab testing for the Lyme disease spirochete.

Below you will find our 1st quarter report for 2020. Our overall requests for service are up about 36%, and rodent requests for service are up 44.7%! This challenging start may be due to residents sheltering in place with plenty of time to explore their home environment. We will see what the future holds.

Alameda County residents, keep in mind when you are visiting our local parks, this is still adult tick season, and you should stay on trails, and do periodic tick checks to make sure they do not get on you, and begin to feed. Wearing light colored clothing will help make ticks stand out and easier to detect.

DEET is still the best tick repellent for use on skin, and only tick repellent recommended by CDC. Permethrin based repellents for use on clothing are also very effective in repelling, and killing ticks.

Below you will find our 2019 year-end District activities report. Overall, service requests were up about 2.1% over 2018. Some of the significant changes were raccoon requests were down 42%; house mouse requests were down 31%, though cockroach requests for service were up about 27%. The largest increase in service requests were in the bee and wasp calls of 54%, which due to the very busy yellowjacket year.

Bats Rabies in Alameda County:

Thus far in 2019 we have detected rabies in seven bats in Alameda County

1. 02/14/2019 Hayward
2. 03/11/2019 Pleasanton
3. 03/21/2019 Hayward
4. 06/10/2019 Sunol
5. 10/07/2019 Fremont
6. 10/11/2019 Hayward
7. 10/23/2019 Livermore

Handling wild animals, especially animals that are acting strangely—seemingly ill, are potential high-risk contacts for rabies transmission. Even if not bitten or scratched, contact with the saliva infected with the rabies virus can be acquired through skin abrasions or mucus membrane. For this reason, any person(s) who had this type of contact should be seen by a physician and possibly begin anti-rabies post exposure treatment. Rabies is virtually fatal once the infection begins, but timely post-exposure treatment can effectively halt the infection.

The periodic discovery of rabid animals (mostly bats; our last rabid skunk was detected in 2005) in Alameda County reinforces the need to keep your pets’ rabies vaccination up-to-date. Contact your local animal control or Vector Control (510)-567-6800), if you notice a suspicious situation involving wildlife, foxes, ferrets or cats and dogs. All mammals are potential victims of rabies, but in Alameda County, as well as all of California, bats are the animals most commonly detected with rabies, followed by skunks.

What is rabies and how is it transmitted?
Rabies is an acutely infectious viral disease that affects the nervous system of humans and other mammals. People get rabies from the bite of a rabid animal. Any wild mammal, like a bat, skunk, or fox can have rabies and transmit it to people. It is also possible, but quite rare, that people may get rabies if infectious material from a rabid animal, such as saliva, gets directly into their eyes, nose, mouth, or a wound. Because rabies is a fatal disease, the goal of public health is first, to prevent human exposure to rabies by education and second, to prevent the disease by anti-rabies treatment if exposure occurs. Thousands of people are successfully treated each year after being bitten by an animal that may have rabies. A few people die of rabies each year in the United States (2018, 2 fatalities)—most of the cases were acquired outside of the US., usually because they do not recognize the risk of rabies from the bite of a wild animal and do not promptly seek medical advice. Bat contact is one of the highest-risks for rabies, especially when people or their pets are exposed and think their incidental contact was so slight that there is not a problem.

Why should I know about rabies?
Rabies is a fatal disease if left untreated soon after the time of exposure. Rabies virus acquired from bats has caused most of the recent human rabies cases acquired in California. Awareness of the facts about rabies can help people protect themselves, their families and their pets. This information may also help clear up misunderstandings about the rabies risk in our area.

During 2018 there were 194 bats detected with rabies in California, 28 skunks, 3 foxes, and 1 raccoon. So far in 2019, there were 188 animals detected with rabies in California; 165 bats, 21 skunks and 2 foxes. In California, from 1997 to 2015, rabies has been detected in 4,560 animals. Bats are the leader with 3,115 detected with rabies, and skunks are behind with 1,264. The next closest runner-up is the fox with 111 and followed by dogs (23) and cats (23). During this same time, period 136 rabid animals were detected in Alameda County (107 bats, 27 skunks, 1 fox, and 1 opossum). There have been eight fatal human cases in California from 1997 to 2014 (four acquired outside California and four acquired from bats in California).

Alameda County is a “declared rabies area” and rabies vaccination is mandatory for dogs over 3 months old. Vaccination helps protect your pet, and reduce the rabies exposure potential to you, your family, and neighbors. If your dog or cat is involved in a bite to a human or other animal, state law mandates “rabies quarantine” (isolation from people or animals) for the biting animal (usually 10 days). An unvaccinated dog, or cat that has contact with a biting animal that is subject to rabies, and that is not apprehended for quarantine or testing, will have to be vaccinated, and undergo six-month quarantine. Vaccinated dogs or cats will have to be re-vaccinated and monitored for 30 days in quarantine. For the above reasons, having up-to-date rabies vaccination is very important to you, your family, and your pet. Six-month quarantine is a long time for a dog or cat to be isolated.

We recently received a large spider for identification; body length about 0.5" and length with legs out, over 2.0". Very impressive looking, and similar in appearance to the Brown Recluse spider (Loxosceles reclusa). This spider came from the Hayward hills area of Alameda County, and arachnid expert from Cal Academy of Science, Darrell Ubick helped with the identification as a Titiotus spp. spider. Though the Titiotus spider looks dangerous, their venom is reportedly not toxic to humans.

The Success of the City of Oakland, Castro Homeless Navigation Center: 12/4/2017-1/8/2019
Prior to the intervention instigated by the City of Oakland’s launch of the Castro Street Navigation Center there were almost 7 blocks with unsheltered camps in the general area between Brush and Castro Streets, and 6th and 5th Streets in Oakland, and an incredibly high Norway rat population and Oriental rat fleas (Xenopsylla cheopis).
With the opening of the Navigation Center, and subsequent cleanup of the surrounding neighborhood, and our efforts controlling the rats over the 13-month life of this rapid rehousing center, the area is almost back to normal. The city was able to help find transitional, or permanent housing for 76% of the participants.
Hats off to the City of Oakland for the humane, and thoughtful process they developed to help the unsheltered in this location and recover the neighborhood for the local residents and business owners.

Found this fellow in our parking lot this morning--male Yellow Sac spider. I have had two confirmed bites by this spider over the years, and both were not very painful; one on the back of the neck (walking in the front door of home, dropped on my neck), and the other on my forehead (I was under my car and it dropped on my forehead). Both bites were slow to heal. The one my neck took a few months, and the forehead took a little over a month, but had a black eschar. Both were small wounds not larger than a pea.
I have great respect for these spider, and their capable biting chelicerae, which they use as a tool to perforate leaves to make them bendable for attaching their retreat sac. So far this year I have found one living in every other grape bunch that I harvested from the grapes growing in my backyard. It is a good feeling to know they not only bite me when they can, but also protect my grapes!
"The bite of a common sac spider (Chiracanthium spp.) can be misdiagnosed as a brown recluse spider bite. Injuries develop in a similar manner but are much less severe. Reactions, such as swelling, slow healing, and ulcerated sores around the bite site, are similar enough to be confusing. If you are bitten by a spider.(WSU Entomology) "

One of the ugliest things in the world is an engorged tick! Check out this American Dog Tick.
"Dermacentor variabilis, also known as the American dog tick or wood tick, is a species of tick that is known to carry bacteria responsible for several diseases in humans, including Rocky Mountain spotted fever and tularemia (Francisella tularensis). It is one of the most well-known hard ticks. Diseases are spread when it sucks blood from the host, which could take several days for the host to experience some symptoms." Wikipedia

Mosquito Awareness Week April 15-22, 2018!
It takes a community to prevent mosquito problems!
We are again receiving abundant precipitation this spring, which could lead to an abundance of mosquitoes, if we do not all take a hand in being mosquito breeding conscious. Residual standing water is of concern because the risk of establishing reproduction sites for mosquitoes near homes; disease-vectoring mosquitoes should not be given a home in your water barrel, your planters, or anywhere!
Because of the ongoing uncertainty of rainfall and water availability during our years of drought, many residents try to save any available water so their gardens and landscaping can survive. All these various water-holding containers provide ample sites for female mosquitoes to lay their eggs, which will pass through complete metamorphosis and may produce hordes of blood hungry mosquitoes that have the potential to transmit deadly diseases, such as West Nile Virus (WNV). Try to keep containers tightly covered, or finely screened so mosquitoes do not have access.
The practice of ‘dumping and draining’ of any container holding water on a weekly basis will greatly reduce mosquitoes around your home and neighborhood. In addition, reporting to Alameda County Vector Control (510-567-6700) any standing water sites that persist for more than a week, or the presence of mosquitoes, that are located in Albany, can help our staff stay on top of mosquito breeding and take measures to prevent the mosquitoes from emerging. There is also a statewide WNV dead bird-reporting website: http://westnile.ca.gov/report_wnv.php where you can report dead birds, which are one of the early warning surveillance tools. Infected birds transport WNV from place to place, and when they are viremic, a local mosquito feeds on them, the virus multiplies in the mosquito, and it can then pass this disease to the next victim. These birds sometime die from this infection, and testing the birds can give an early warning of WNV in an area.
Alameda County Vector Control has a comprehensive mosquito surveillance and control program in Albany that with the help of our community will be able to keep Albany safe from disease-vectoring mosquitoes. Twenty-seventeen was a very bad year for WNV in California, with 553 cases statewide and 44 fatalities. In Alameda County, there was one human WNV illness, two dead birds tested positive for WNV, but no mosquito samples were positive for the virus. Thankfully, none of the WNV activity was in Albany.

Please come clean up all of the dead bird carcasses on Oak street between 10th & 11th. I just had to get rid of a moth infestation in my apartment caused by the bird dander, feathers, and bodies outside of my apartment. This is a major public health issue.
Can someone tell me if this is a vole? It's body about 4 inches long.
