We often see many of our clients unsuccessfully attempt to solve the squirrel problem in their attic by performing tree pruning and even removing a valuable shade tree! Not only can this be expensive, but it very rarely works. While it’s good to trim back branches and vegetation that may touch your home to prevent some moisture and insect invasion, especially Carpenter Ants I have never seen it keep squirrels from accessing the openings at the roofline.

Tree squirrels are very good climbers and quite adept to solving access obstructions. Elizabethan style collars installed around electric and utility lines (with the owning companies permission) does work in some instances to keep them from “Running the Wires” to enter but I have personally witnessed a Gray Squirrel tip the upper portion of a collar down enough to jump over the collar to the wires on the other side. Squirrels can gain easy access to the roof by climbing on your gutter downspouts, utility and A/C lines. These adept climbers can also run directly up the wooden shingled siding, easily obtain grip to brick and stucco to run directly up any side unaided by gutter downspouts, conduits, vines, etc.

While it IS possible to prevent these expert climbing rodents from getting to the roofline, the process and cost of modification may far exceed the expense associated with simple evacuation and reinforcement to vulnerable areas with stainless steel mesh or other permanent materials.

Rat Bites Subway Rider at Station

New York transit workers said a rat bit a subway rider on the foot while she was waiting for a train at a downtown station.

Transit sources told the New York Daily News the woman, who was described as in her 20s, was sitting on a bench at the Brooklyn Bridge-City Hall station at about 9:30 a.m. Monday when the rodent ran up and bit into the flesh of her foot.

"She was pretty frantic and upset," one transit worker said. "You could actually see the bite."

Authorities said the woman was treated at New York Downtown Hospital and released.

Officials with Transport Workers Union Local 100 said rats are becoming more common at stations because of infrequent garbage collection and poor seals on trash storage rooms.

City transport officials declined to comment, the Daily News said.

Defending itself from a lawsuit claiming that an Illinois man found a dead mouse inside a can of Mountain Dew, PepsiCo contends that a rodent would have disintegrated and been transformed into a “jelly-like” substance between the time of the soft drink’s bottling and the day the plaintiff reportedly purchased the soda from a vending machine at his office. In a court response to a motion filed by Ronald Ball--who claims to have found the dead mouse in a Mountain Dew can about three years ago--PepsiCo filed a fascinating/revolting affidavit from Lawrence McGill, a veterinarian who noted that he was “familiar with the effects an acidic fluid, such as common soda drinks including Mountain Dew, will have on mice and other animals.”

According to McGill, if a mouse is submerged in Mountain Dew between four and seven days, the rodent “will have no calcium in its bones and bony structures.” During those days of soft drink immersion, “the mouse’s abdominal structure will rupture.” Additionally, “its cranial cavity (head) is also likely to rupture within that time period,” McGill noted.

After 30 days exposure to Mountain Dew, “all of the mouse’s structures” would have disintegrated to the point that it would not be recognizable. In fact, “the mouse will have been transformed into a ‘jelly-like’ substance.” The only part of the rodent that could possibly survive, added McGill, was “a portion of the tail.”

PepsiCo contends that Ball, 52, opened his can of Mountain Dew 74 days after it was bottled at a PepsiCo facility in St. Louis. The company alleges that Ball has provided “no evidence” that the mouse was inside the can when it was sealed in August 2008.

In his Illinois Circuit Court lawsuit, which is pending in Madison County, Ball alleges that he opened the Mountain Dew can, “took a drink, and immediately became violently ill such that he began to vomit.” Subsequent to Ball being stricken, “the contents of said can of Mountain Dew were immediately poured into a styrofoam cup wherein a dead mouse was found.”

The rodent was eventually turned over by Ball to a PepsiCo insurance adjuster. McGill, pictured above, subsequently examined the animal and concluded that it was a young mouse or rat, no older than four weeks old at the time of its death. The rodent, according to his affidavit, had not even been born when the Mountain Dew can was sealed, and was already dead when it “entered the Mountain Dew fluid.”

McGill reported that the pH level of Ball’s Mountain Dew can was 3.43, which according to the veterinarian “indicates the fluid was acidic and within the normal range for Mountain Dew.”

UPDATE: Wal-Mart Deli, Bakery Reopen After Rodent Problem

The deli and the bakery at the Wal-Mart superstore in Lebanon have reopened after being shut down for a rodent problem.

News 8 initially reported the problem on Thursday, Aug. 4. A store spokeswoman said the problem was first discovered at the end of June but that pest control efforts were unsuccessful. The spokeswoman would not say what type of rodent had gotten into the store.

Here is the complete statement the company issued on Thursday:

"Unfortunately it has come to our attention that rodents have found their way into our store in Lebanon, Pa. We are aware of the situation and we are working to resolve this issue.

As part of our commitment to food safety, the bakery and deli remain closed until the problem can be corrected. We’re working with a pest control company, a professional cleaning service and the Department of Agriculture to remedy the situation.

We make every effort to ensure our stores are clean and pest free and apologize to our customers for this inconvenience. Once the Department of Agriculture inspects our store and gives us the okay to re-open, we will."

On Friday, a company spokesperson updated the situation, saying the store had passed the inspection and the deli and bakery are open for business

Rats, Mice, and Robots
Boston University Researchers’ aim: replicate rodents’ location-finding sense, install it in robots

Biologically, says BU scientist Michael Hasselmo, it’s easy to see the benefit of accurate tracking of location. “If a rat is running down an alley and it finds a nice big garbage can filled with leftover Chinese food, it’s very useful to be able to find that location again,” he says. “And conversely, if he is walking down an alley and a cat comes out and chases him, he might want to remember where exactly he got chased."

Ultimately, he says, the goals of the MURI grant include understanding how rats keep track of their location and applying that mechanism to robots, so robots can work as a sidekick to soldiers searching dangerous buildings and alleyways. Ideally, the robots will navigate strange spaces and report back to their human colleagues on the exact locations of bombs and other dangers.

A fifth case of Hantavirus has been confirmed in New Mexico.

The New Mexico Department of Health says a 59-year-old woman from McKinley County is hospitalized at University Hospital in critical condition with the infection.

Three people have died from Hantavirus in the state this year while a 39-year-old man from McKinley County has recovered from the infection, which is transmitted through rodents feces, urine and saliva. People usually catch the infection by breathing in dust from areas of rodent infestations.

Early symptoms of Hantavirus infection include fever and muscle aches, possibly with chills, headache, nausea, vomiting, diarrhea, abdominal pain and cough, which progresses to respiratory distress.

Symptoms develop within one to six weeks after rodent exposure. Chances for recovery are better if medical attention is sought early.
