Guide to IPM in Long-Term Care Facilities

Don’t Get Sick from Pests, Get Rid of Them

A Guide to Keeping Your Residents – and Your Business – Safe from Ants, Rodents and Other Harmful Invaders

By Zia Siddiqi, Ph.D., BCE and Frank Meek, BCE

Nursing home administrators agree that providing a healthy environment for residents is a top priority.  Keeping pests out, of course, is part of that mission.  Lethal fire ant attacks in recent years have made the public and industry insiders all too aware that pests can be a very real threat to patients.

But pests also threaten nursing homes themselves.  Negative publicity from an infestation can ruin a facility’s reputation, and multi-million dollar lawsuits can put the business on the line.  Last April, for example, a Houston nursing home was hit with a $1.5 million judgment after a resident was killed as a result of more than 2,000 fire ant stings.

Unfortunately, long-term care facilities are inviting targets for many pests.  Heavy traffic in and out of multiple entries, combined with busy food service, laundry and storage areas, make effective pest prevention daunting.  Making the task even harder, pesticides must be used sparingly if at all.  Overexposure to certain pesticides can cause adverse health effects, especially among older or immunocompromised residents.

Administrators must know which pests to prevent, and where the facility’s vulnerabilities are.  Typically, one or more of five pests cause the most trouble, and certain areas within nursing homes are more susceptible to infestation.
What you are up against

  • Ants
    Pharaoh ants have been known to climb into open wounds, IV bags or used bandages.  Because they nest in walls, pharaoh ants can be difficult to find and control once they become established.  The wrong control procedures can lead to a disaster.Fire ants, particularly the red imported variety, can be an even greater health threat.  They have attacked residents or patients in health care facilities in more than ten documented cases, several of them fatally.
  • Flies
    Flies are more than a nuisance; they also can spread germs rapidly.  Covering distances quickly, they might feed on garbage one minute and a resident’s food the next.  Flies carry staphylococcus, E. coli and salmonella, and can drop bacteria wherever they land. They reproduce rapidly and are hard to control once they gain entry.
  • Cockroaches
    The mere sight of a cockroach is enough to startle and disgust residents and families.  But, more alarming to nursing home administrators, roaches carry germs that can cause pneumonia, diarrhea and food poisoning.  Cockroach droppings can also inflame allergies or asthmatic conditions.
  • Rodents
    Rodents are keenly aware of and attracted to the food served throughout long-term care facilities. In the Middle Ages, rats carried the Black Plague through their fleas.  Today, rodents carry diseases with perhaps less menacing names – Hantavirus and typhus – but with dangerous symptoms.  Most recently, scientists found that rats in Hong Kong were transmitting SARS.  In addition to threatening residents’ health, rodents also can cause property damage by chewing and burrowing in walls or other structures.
  • Birds
    While often not regarded as pests, birds can infect humans with up to 40 viruses and 60 transmutable diseases, including salmonellosis, a form of food poisoning, and encephalitis, or inflammation of the brain.  If left unchecked, dried bird droppings can enter a building’s ventilation system and be inhaled by residents and employees. Inhalation of these airborne particles can cause histoplasmosis, a potentially fatal respiratory infection.

Where is the fight?

Pests will infest any location where they can find food and moisture.  Many nursing homes, unfortunately, offer both in abundance.

The residential setting within a long-term care facility is the first “hot spot.”  Depending on how vigilant the housekeeper, a room or apartment may become attractive to pests.  If residents leave food out or otherwise fail to keep a clean living space, pests will likely appear.

Many nursing homes have multiple dining areas with one or two full kitchens, creating the same pest challenges that restaurants face.  With food being delivered on a regular basis, pests can hitch a ride into the kitchen on incoming parcels or work their way in through open doors, cracks and crevices.  Because food is being prepared, care must be taken to limit chemical applications when planning a control strategy.

Employees, too, can create an environment favorable to pests.  Locker rooms or break areas can be inviting if employees bring their own food to work.  Pests will find food that is left in a locker or closet.  In addition, employees may bring bags, jackets, extra shoes or other accessories on which pests can sneak into nursing homes.

Ironically, areas dedicated to cleanliness can pose problems.  A janitor’s supply closet might stay locked most of the time, preventing regular treatment by a pest management professional.  Wet mops or buckets of water provide a moist haven for many insects.  In the laundry room, stacks of dirty clothes provide shelter and warmth for pests.  And, if the room is used heavily, finding time to treat it might be difficult.

How can you treat these areas safely and effectively?  Integrated Pest Management (IPM) is a philosophy that stresses a combination of chemical and non-chemical methods to control pests.  The driving principle behind IPM is that by making an environment unattractive to pests you can control the problem with limited pesticide use.

Making your facility “hostile” to pests
Pests won’t infest a place that doesn’t give them what they need.  Generally, this means food, water and shelter.  As noted earlier, the variety of microenvironments within a long-term care facility make it a tough place to treat with one set of procedures.  For example, you can’t always use the same techniques in a resident’s room as you would in a food preparation area, dining area or laundry room.  But there are some basic IPM building blocks that are useful in multiple areas.  Let’s take a look at some of these practices, working from the outside in:

  • Mount outdoor fluorescent lights at least 100 feet from the building to draw flies and other flying insects away from the entrance doors.
  • Use sodium vapor lights for entrances and exits.  Insects are less attracted to these light sources.
  • Make sure that all exterior doors fit tightly and caulk any and all crevices, especially those on the exterior of the building(s).
  • Install ultraviolet light traps near service doors and loading docks to intercept flying insects before they enter the building.
  • Inspect shipments for pests or evidence of pest presence such as droppings, chew marks or exoskeletons before bringing them in a receiving area.
  • Make sure your vendors are taking steps to prevent pests from infiltrating their deliveries while in transit or storage.
  • Minimize airflow from the outside at receiving areas by using plastic-strip doors.  Unpack shipments and dispose of any empty boxes.
  • Make sure floors stay free of litter, food and other debris.
  • Cover and seal bulk food-storage containers and garbage containers.
  • Store mops, brooms or other cleaning supplies off the floor in a housekeeping closet.
  • Do not place storage racks flush against the wall.  As a general rule, keep an 18-inch gap between the wall and the rack.
  • Install fly lights or glue traps if you have any fly “hot spots” inside the facility.
  • Check and clean floor drains on a regular basis.  Flies will breed in clogged or filthy drains.
  • Keep tiled ceilings intact.  Broken or missing tiles should be replaced.  Ceiling voids can be used as a crawl space for rodents or a breeding ground for flies.
  • Maintain a strict waste management system by securing trash bins throughout the building.  Empty trashcans regularly and schedule periodic pickup, so collected refuse doesn’t sit around the building.
  • Make sure food isn’t left in employees’ lockers overnight.  Provide a secure storage area, such as a refrigerator for all food.  Require workers to regularly clean out their lockers, giving a pest management technician a chance to treat the area.

Choosing a pest management professional

Because unchecked pest infestations and the misapplication of pesticides could both be serious blunders for a long-term care facility, many choose to outsource their pest management to trained professionals.  In most cases, professional pest management providers have the advantage of in-depth scientific knowledge about pest behavior and years of experience in pest prevention.

Because there are numerous pest management providers to choose from, narrow the field by asking industry colleagues about reputable companies.  When discussing potential providers, ask questions that separate credible, experienced providers from the rest, such as:

  • Does the provider specialize in commercial pest control?
  • Are the provider’s technicians aware of the special needs of a long-term care facility?
  • Is the provider a member of national, state or local pest control associations?
  • Are the provider’s technicians licensed and/or certified by the state?
  • What kind of training do the technicians receive?
  • What is the average response time to an emergency?  Is there an extra charge for such emergency responses?
  • Does the provider offer a money-back guarantee on its service?
  • How long has the provider been in business?

Once you have a handful of companies on your list, you will need to examine them more closely to choose the right one for your needs.  Here are a few tips:

  • Contact three or four companies and insist that they tour your facility before submitting a bid.
  • Ask a lot of questions on the site tour.  Professionals will know the answers.
  • Be sure to address which specific pests are included in the contract.  Ask about additional charges when extra services are needed for a non-contracted pest.
  • Make the purchase decision based on value, not price.  In many cases, the lowest priced service does not equate with other bids.  Be sure you are comparing “apples to apples.”

A process, not an event

Because of the multiple sensitive environments that exist, a thorough and customized IPM plan is the best way to protect and treat a long-term care facility.  IPM is not a one-time event.  Instead, IPM calls for ongoing sanitation, pest monitoring and prevention.  Nursing homes can treat the cause of pest problems rather than the symptoms by making a facility unattractive to pests instead of trying to eliminate pests when they are found.  The bottom line: Effective IPM is a joint venture of the nursing home staff and the pest management provider.  Pest management programs that adhere to this philosophy are the most effective way to prevent pests over the long term in nursing homes and many other commercial environments.
