RI, MA EHS Pest Control Blog

It is amazing when you really analyze what mice can do once inside your home. Granted we in the pest management industry see things differently than the general public, its called “pest control eyes.” It is more than eyes, it’s a smell, a sound, a feeling, a sort of 6th sense that we are equipped with.

Mice will visit food sources and preferred routes around your house 200-300 times per night! Mice have lanolin on their fur, it is an oily substance that enables them to squeeze into tight cracks and crevices with ease. In doing this they create rub marks on their frequently travelled paths. This looks exactly like the dirty smears you would find around a light switch that is used often my various people. In the attached picture you will see the hole the mice made in this homeowners insulation in their basement with the rub marks leading into it. This person had a sizable mouse issue that they tried to treat on their own and obviously failed miserably. No worries, EHS to the rescue!!!

Alcoholic Mice Live to Drink

A new line of mice, bred to prefer alcohol over all other beverages, is expected to offer insight into the role genetics and lifestyle play in alcoholism. The mice drink more alcohol than other animal models and consume it in a fashion similar to humans: choosing alcohol over other options and binge drinking.

A study published in the journal Addiction Biology reports the mice reach blood-alcohol levels of more than 260 mg/dl of alcohol daily—over three times the equivalent of the human legal driving limit and the approximate consumption level that the severest human alcoholics attain.

“The free-choice drinking demonstrated by the new mouse line provides a unique opportunity to study the excessive intake that often occurs in alcohol-dependent individuals and to explore the predisposing factors for excessive consumption, as well as the development of physiological, behavioral and toxicological outcomes following alcohol exposure,” says senior author Nicholas Grahame, a biopsychologist specializing in alcoholism at Indiana University.

According to the National Institute on Alcohol Abuse and Alcoholism, part of the National Institutes of Health, an estimated 17.6 million Americans abuse alcohol or are alcohol dependent. Alcohol abuse and alcoholism can be treated but cannot be cured.

Mice share 80 percent of their genes with humans, so they are an excellent model to study alcoholism, a disease with a strong genetic component. The risk of developing alcoholism is known to be influenced by lifestyle. Animal models allow researchers to employ methods that they are unable to use in humans.

“This line of high-alcohol-seeking mice should be able to give us a better understanding of the basic brain mechanism involved in alcohol consumption as well as greater insight into the toxic effects on the brain, with the goal of developing therapies,” says Grahame, whose research focuses on behavioral genetics and behavioral pharmacology.

As with humans, the mice become intoxicated when the pace of alcohol consumption is faster than the liver can eliminate it. Typically it takes six or seven hours of continuous alcohol drinking for the new strain of mice to reach the highest levels of intoxication.

Doctoral candidate Liana M. Matson is a co-author of the study. She has conducted research focusing on when the mice drink and determined that they are nocturnal drinkers. This knowledge enabled the mice’s blood-alcohol levels to be tested when at their highest level.

Undergraduate School of Science students Amy Buckingham and Nick Villalta assisted in the research by measuring intake and blood-alcohol levels in the new strain of high-alcohol-seeking mice. In a related study, they analyzed how drunk the mice became by testing how the animals performed on a balance beam.

The research was funded by NIAAA and the School of Science at IUPUI.

HantaVirus Found in Trapped Rodents

Six rodents trapped during routine monitoring in the last week in North County and East County have tested positive for the potentially-deadly hantavirus.

Infected rodents rarely pose a danger to people if they are in the wild and there has been just one non-fatal human case in the county, in 2004. But people can inhale hantavirus by stirring up rodent droppings, then get sick and even die. There is no treatment, vaccine or cure for hantavirus infections, which are deadly in 38 percent of cases.

“People should never sweep up or vacuum rodent droppings or nesting material when they find it,” said Jack Miller, director of the County Department of Environmental Health. “Instead, they should ventilate closed areas for at least 30 minutes, and then carefully use bleach or a full-strength disinfectant before removing them.”

The best way people can prevent the disease is to keep mice out of houses, garages and sheds by sealing holes larger than the size of a dime, County officials said.

Hantavirus can cause hantavirus pulmonary syndrome (HPS), which begins with flu-like symptoms but can grow into severe breathing difficulties and even death.

The rodents that tested positive during the last week included: two deer mice from Campo; one deer mouse each from Carlsbad and Escondido; one harvest mouse from Oceanside and a vole from Carlsbad. Thirty-seven rodents have tested positive for hantavirus in the county this year, compared to 21 in 2010.

In today’s tough economic and housing climate there are residential houses that are vacant for extended periods of time. Months long is not uncommon and in some cases it may be a year or more. It is worse when it is a foreclosure when the occupants leave with no notice and leave many possessions behind. In some cases they leave behind food items, grass seed, bird food, pet food, etc. A total buffet for pests!

The problem with houses like this is that pests often find the house and can get out of hand in a short period of time. Mice are a perfect pest for these situations. They are prolific breeders so in 3 months the number of mice in a home can quadruple! The environment is perfect for them, the house is vacant, quiet, dark, and there is always food and nesting material left behind.

The attached picture shows you exactly this scenario. Mice got so out of control in this vacant house that they created heavy runways (travel routes) into voids. The picture shows a gnaw hole created into a floor void from the basement level. You can see the “greasy” rub marks that are created when mice frequent the same paths. These rub marks are from the lanolin (oil) on their fur. In this case the buyers home inspector pointed out that there was a high level of mouse activity and they should contact a professional. EHS performed an initial treatment and excluded the mice out at the foundation level. We then did a 30 day follow up and have a 6 month follow up on the books. The treatment program with 1 year warranty was enough to satisfy the bank plus buyer and the home was sold. See, professional pest control is good for the economy!

It is scary what some commercial businesses, property managers, and homeowners do! The attached image show’s someone that tried to do their own pest control to solve a mice issue. As you can tell there is a tremendous risk to safety!

There is a reason why professional pest control makes sense, we are licensed and highly trained professionals. When it comes to protecting public health & safety you should never look for the quick and easy fix…..call a professional like EHS. You are risking WAY TOO MUCH if you cut corners!

Mice are about as adaptable as any animal on the planet! I have seen mice eat things that humans would not even remotely consider tasting let alone eat! Ketchup is certainly an edible food but not exactly a meal…..except for mice. The attached image shows that mice completely cleaned out an individual packet of ketchup. Just this little amount of food is enough to support a mouse infestation.

This packet was found in a soon to open restaurant. Needless to say they needed EHS to protect the facility and their reputation before they even opened their doors. They put their trust in EHS and we take it seriously!

This is a very important saying here at EHS and it is so fitting! Most people do not have the keen senses that pest control professionals have. We walk into an area and it is like we have super hero skills or an extra sense.

It is pretty cool! Most of the public will never ever observe what us pest management professionals see. I was on a bedbug inspection when I observed the ceiling light fixture loaded with mouse droppings. Needless to say we needed to control the mice plus bedbugs.

The newest deterrent to would-be terrorists at airports might just be mice. An Israeli company, BioExplorers, has created a detector that looks like a full-body scanner, but actually contains three compartments containing eight mice, according to the Telegraph.

The mice will work four-hour shifts and are, according to researchers, more effective than dogs or x-ray machines, according to the Daily Mail. Air is pumped into the mice chamber every four hours so the animals can breathe.

When a mouse picks up a trace of something curious, they are trained to flee to a side chamber, which triggers an alarm (to prevent false positives, more than one mouse has to flee).

Mice take roughly ten days to learn their first smell and unlike dogs, they don't need interaction with trainers or constant attention.

The device was first tested on shoppers last year in Tel Aviv when mice picked out 22 people carrying mock explosives

Westlake High Cafeteria Closed Down by Rodent Infestation

The cafeteria at Westlake High School in Thousand Oaks was shut down earlier this week because of a rodent infestation and unsanitary conditions, officials said.

County environmental health inspected the site Tuesday and suspended its license until the problems could be resolved. The cafeteria was closed Wednesday and has remained shuttered as staff correct the issues, said, Superintendent Jeffrey Baarstad of the Conejo Valley Unified School District.

In the meantime, the county OK'd the school serving prepackaged food on the quad. That food is prepared in the district's central kitchen.

"We've been aware of the problem," Baarstad said. Over the past week and a half, the school used exterminators and worked to stop rodents from getting inside the building but wasn't able to fix the problem in time.

The issue likely stems from extensive renovation work on the large building that houses the cafeteria, kitchen and theater, along with the site's proximity to a barranca and the hillside. Rodents can squeeze in any gap or hole left unsealed — even if it's just the size of a quarter, Baarstad said.

Maintenance staff at the school are working to seal any holes, exterminators are getting rid of rodents already inside and cleaning crews also are working on the site, according to the district.

Baarstad hopes to be ready for inspection as early as Monday. With an OK from the county, the cafeteria could reopen by Tuesday.

The environmental health agency inspects about 4,000 food facilities throughout the county, including restaurants, markets, produce stands and more, said Elizabeth Huff, manager of the community services section of environmental health. School cafeterias are inspected two to three times a year to make sure they are in compliance.

Westlake High sent letters home with students on Wednesday to let them know about the closure.

"It's certainly not the letter you want to write home to parents," Baarstad said. But there were reasons why it happened, and the district is working to make sure all issues are cleared up, he said.

What you don’t know CAN hurt you! If you could only see behind the scenes like we do in pest control you would be amazed at what we find! We are talking food handling facilities or restaurants. That serve the general public!!! Some of them are historic eateries in their cities & towns! You hear about all the dangers of uncooked food and what it can do to you. What about the dangers of pests? The attached image is damaged corn from mice and it was in a walk-in refrigerator. This restaurant asked us to come in and solve a mouse issue they were having as their previous pest control company could not solve it. The problem had been going on for YEARS! Mice are eating their food supplies and what they did not eat they urinated and defecated on! Needless to say they had a CRITICAL pest issue.

Why did they let this go on for years? Where are the health agencies that are supposed to be protecting public health?

EHS solved the problem with an aggressive pest control program. I just do not understand why restaurant owners tolerate pests as it can destroy their reputation and may even harm the general public.
