Poison Ivy – Don’t scratch

“Lewis Ziska, one of the lead scientists on the six-year study in a forest at Duke University, found that with increased atmospheric CO2 we get bigger, stronger, leafier poison ivy.” – Mary Woodsen, Poison ivy (like the Rolling Stones said …)

Just what we needed. Bigger, healthier, more toxic poison ivy.

Poison ivy has a wide variety of habits – it’s often a climber with thick, woody vines. The vines are covered with rootlike hairs that help it cling to tree trunks or fences, which is a great way to distinguish it from other vines such as Virginia creeper. You will likely see this form most often on school grounds as it climbs fences, trees, and buildings.

It can also be standalone plants with a groundcover quality to them. And it can present in a shrub-like manner – most commonly seen along woodland edges.

The famous saying, “Leaves of three, let it be” is the one feature common to all growth forms. Those leaves, however, can range from ½” on new plants to over 5 inches long on older plants. They are usually smooth, but they can be toothed and sometimes lobed. Young leaves are usually reddish, older leaves can be a deep green, turning red or yellow in the fall. Shinyness is an option, therefore you can’t count on it to confirm your identification.

It's in there, and a quick inspection could have saved me a lot of itching.

Poison ivy is in there, and a quick inspection could have saved me a lot of itching.

And sometimes, it’s just hidden. As I type this blog, my fingers are pink with calamine lotion and I am trying desperately not to rub them against my pants. After a trying day, I vented my frustration on a neglected mulched area under a tree. I noticed the small poison ivy plants tucked into the other weeds only after I had ripped them out with my bare hands. I washed my hands with soap and water to remove the offending urushiol, the toxic oil that causes the dermatitis. But I wasn’t fast enough. A few days later, here come the blisters.

So, the motivation to check the NYS IPM resources on poison ivy management was strong. Here’s what I found on the School IPM Best Practices website:

Give it a trim. Often

Take a closer look. The leaves of three are less obvious when poison ivy gets bushy.

Poison ivy does not like to be trimmed. Mowing or cutting back young growth will deplete the energy in the roots. Plant stems, aerial vines and underground creeping stems are all capable of producing new nodes and leaves, so continue to monitor and trim. For best results, cut back new growth at the base of the plant.

Using a weed whacker is not recommended without full protective gear as plant material can be kicked back and land on exposed skin. Or in your eyes (shudder).

DO NOT BURN! The oils can be distributed through the smoke. It’s bad enough in between your fingers. You do not want to experience that kind of rash in your lungs.

Spot applications of a nonselective herbicide can be helpful for hard to reach locations or if you are extremely sensitive, but you need to follow the regulations laid out in the Child Safe Playing Fields Act and other state regulations. And remember, plants killed by herbicides will still have urushiol and can cause a rash.

In fact, the longlasting oils are present on all parts of the plant whether the plant is actively growing, dormant, or dead. So…

Wash your equipment!

Once on skin, tools, clothes, boots, and gloves, the oils need to be removed with soap and water. If you mowed poison ivy, urushiol may still be present on the mower blades the next time you remove them to sharpen them. If you used goats (yes, goats have been used to remove poison ivy), it could be in their hair. Take precautions.

And, for goodness sake, give a quick visual check before plunging into handweeding.

One last thought – according to the Cornell Lab of Ornithology, poison ivy “produces just the kind of fat-rich berries that are essential for sustaining migrating birds during fall and year-round residents in the winter”. So if you have poison ivy in an out-of-the-way area, consider leaving it behind for its wildlife value.

Now, if you will excuse me, I need to take another benadryl.

 

 

Bed bugs in schools aren’t going away

“Coming together is a beginning. Keeping together is progress. Working together is success.” –Henry Ford

Bed bugs in schools are an issue that is not going to disappear. We have many resources available to help people deal with the issue, but, as is often the case, these resources are not looked for until there is a crisis.

Finding a bed bug in any situation can be distressing, but should not be a cause for panic.

This became clear, once again, as a distraught school official called to ensure that the pesticide application they were planning was legal. When asked if the pesticide applicator had found an infestation, the answer was “We know there isn’t one”. The strategy had been to spot treat when a bed bus is found. But the problem has escalated. Parents are pulling their kids from school. The union is involved. Finger pointing is rampant. The pesticide application was planned to show that SOMETHING is being done.

But we know that it isn’t going to help. Eliminate every bed bug in a building and the very next day a student or staff member can bring in another hitchhiker from an infested home.

So what is the solution?

Bed bugs are, simply, a community problem. It is nearly impossible to determine who is at fault and laying blame is pointless. The old saying states that it takes a village to raise a child. It also takes a village to deal with a bed bug problem.

First, know that it is nearly impossible to prevent bed bugs from entering any public facility. They will hitchhike on personal items from infested homes. These introductions are common in schools, office buildings, movie theaters, retail stores, libraries, taxis, buses, trains, diners,…

Bed bug infestations are rare in schools, but introductions from infested homes, usually on personal items that travel from home to school and back again, are quite common.

Second, infestations do not happen unless bed bugs have the opportunity to feed. They hate disturbance, prefer darkness when feeding, and need a body to be still, usually for two hours or more – not conditions typically found in schools.

Third, especially in apartment units, a family might be doing their best to control bedbugs, but a neighbor’s untreated apartment can lead to constant reinfestations. And there are multiple reasons for residents to not report bed bug infestations within their apartments, including:

  • Bed bugs might not have been noticed. Not everybody reacts to bites.
  • Residents are ashamed or embarrassed. Despite the fact that anyone can get bed bugs, there is the false stigma that bed bugs are associated with poverty and unsanitary conditions.
  • There is a risk of being charged for treatment or being evicted, even when the landlord is responsible.
  • Treatment is expensive and the resident might not have the resources to hire a pest management professional.

A national organization called eXtension has developed an IPM Action Plan for Bed Bugs that addresses the responsibilities of the school community and parents (and, in extreme cases, local government). Both lists include education. The NYS IPM Program can help with educational resources (below) and workshop opportunities.

The Action Plan goes on to discuss procedures that should be followed if a suspected bed bug is found and what to do if children repeatedly come in with bed bugs. It even provides recommendations for further intervention when children continue to come in with bed bugs despite interventions. A small sample of listed procedures include:

  • If a confirmed bed bug was found on a child then the school nurse should inform the child’s parents. [A letter and] inspection report should be sent home with the student. (See Bed Bugs: What Schools Need to Know fact sheet for a good sample letter). Educational materials should accompany the letter.
  • In most instances students should not be excluded from school due to bed bugs. Schools should not be closed due to the discovery of bed bugs unless there is a widespread infestation [which is rare].
  • In an infested home, parents should store their child’s freshly laundered clothing in sealed plastic bags until they are put on in the morning. This prevents bed bugs from hiding in the clothing and being carried to school.
  • Backpacks, lunchboxes and other items that travel back and forth to school can also be inspected daily and stored in sealed plastic containers at home to prevent bed bugs from getting into them. [Backpacks can also be treated in a hot dryer.]
  • At school a “hot box” might be used to heat treat belongings possibly infested. A hot box is an insulated container with a heating element that raises the temperature above 115 degrees, killing bedbugs. They can be purchased for a few hundred dollars. Dryers that contains shelves will also serve the same purpose.

Action plans can then be formatted as a flowchart, making decision making simple to understand and follow. The Michigan Bed Bug Working Group put together the Bed Bugs: What Schools Need to Know fact sheet with a sample flowchart.

This flowchart is part of Bed Bugs: What Schools Need to Know. The fact sheet also includes a sample parent letter.

We recommend that every school develop a bed bug policy based on the recommendations within the IPM Action Plan for Bed Bugs and use NYS IPM Program resources to help educate the school community and beyond regarding bed bugs and how to deal with them.


NYS IPM Bed Bug Resources

And be sure to check out a potential grant opportunity to help the school community purchase the airtight containers and heating units needed to help prevent bed bug transportation. The Walmart Foundation Community Grant Program offers grants ranging from a minimum of $250 to the maximum grant of $5,000. We do not know if they have ever funded this type of project, but let us know if you are successful!

Online School IPM Resources to assist IPM Professionals with their Programs

Thank you to Janet Hurley, Texas A&M AgriLife Extension Service, for her dedicated effort to progress school IPM and for allowing us to use her post.

In 2014, a number of collaborating institutions led by Dawn Gouge, University of Arizona and Janet Hurley , Texas A&M AgriLife Extension received two separate grants from the Environmental Protection Agency (EPA) to provide online resources on integrated pest management (IPM) for school personnel. The Stop School Pests team used their grant to focus on education and training for personnel, while Hurley and collaborating scientists created a one-stop online “big box store” of IPM resources, including documents, training, pest ID pamphlets, state legislation and more.

stop-school-pests-urlThe training website, Stop School Pests, resulted from a collaboration of 42 people from federal and state agencies, universities, school districts, tribes, advocacy organizations and industry. Together they proposed to build a resource that would increase IPM adoption in K-12 schools and reduce the risks from pests and repeated pesticide use.

stop-school-pests-modulesStop School Pests provides modifiable PowerPoint presentations for in-class teaching and self-guided online courses. Lessons are specific to different roles within a school, so that facility staff will have access to materials specific to them.

While some groups, such as facility managers and maintenance personnel, were eager to delve into the materials, others such as nurses and teachers initially did not think the subject matter pertained to them. However, several who participated in some of the in-class lessons said that they did not realize how much they did not know about pest management and were glad that they took the lessons.

“I have been a school nurse for 25 years, and I cannot believe I learned so much helpful information in just one hour,” said Mary Griffin, a nurse in Arizona, after attending a training session piloting the Stop School Pests School Nurse Module.

A softball coach said that she did not realize that spraying pesticides without a license was illegal in her state until she went through the training.

For personnel who need specific information or don’t know where to turn once a pest problem starts, the iSchoolPestManager website provides over 1,000 resources, including the educational materials from the Stop School Pests project.

The iSchoolPestManager site was built as a searchable online mine of school IPM resources from every state. Staff from Texas A&M AgriLife spent several months collecting materials; then volunteers from throughout the country, even one from Israel, painstakingly combed through them to eradicate duplicates, outdated materials or references to materials that no longer existed. The initial 1,315 resources were pared down to 1,045 entries. Staff at the Pesticide Information Center in Oregon helped design and build the website. The website currently has 1,065 documents to assist everyone with adopting, maintaining, and sustaining their IPM program.stop-school-pests-website

Search for all sorts of documents by going to the show me everything tab.

The site is formatted for a standalone computer, with a separate link that will bring up special formatting for a smart phone or tablet. Resources are divided into four areas: geographically specific, professional trainings and other materials, insect-specific information, and groups of documents such as fact sheets, regulations, checklists and more.

Rather than duplicate information already provided at other websites, Hurley decided to link to them. For instance, self-paced instruction under “Training Modules” links to pages hosted by eXtension. Some of the PowerPoint presentations are located at Bugwood. Some of the educational links go to videos at university websites.

While the amount of information in iSchoolPestManager might seem overwhelming at first, users looking for specific information will be able to use the headings and sections to locate what they need more easily.

Pesticide Misapplications? The Costs Are High

A chemical smell wafting through an upstate middle-school classroom last fall ended up sending six students to the hospital. What happened?

A member of the custodial staff sprayed wasp killer by a fresh-air intake. Some of that spray ended up in a second floor classroom. Fourteen students and two staff members felt ill, according to a newspaper account; in fact, the school was evacuated for more than a half hour.

Need help identifying a pest and what to do about it? What’s Bugging You? has the information you need.

The school was fined $5,500 for violating three pesticide regulations. But incidents like this are preventable by practicing integrated pest management.

The NYS IPM Program offers resources such as this video about stinging insects and IPM strategies that reduce the risk of stings.

Many state regulations pertain to pesticide use in and around schools. You can find a synopsis here. But first and foremost — anyone who applies pesticides on school property must meet pesticide application certification requirements. (The same applies to child care centers, office buildings, or any other commercial or public property.) If the certified applicator is a school employee, then the school itself must be registered and appropriately insured.

Neither the school’s pesticide-application notification requirements nor the Child Safe Playing Fields Act were violated, since each provides exemptions for the use of small containers of aerosol products in an imminent threat from stinging and biting insects. Regardless, a certified pesticide applicator must apply them, and, if applied by a school staffer, the school must be registered.

School staffers can obtain and maintain commercial pesticide licenses after getting the right education credits and passing their exams. You can find information about pesticide certification on the Pesticide Safety Education Program website, including information about upcoming classes.

Organizations such as BOCES and CASDA often ask NYS IPMers to present at their conferences.

Organizations such as BOCES and CASDA often ask NYS IPMers to present at their conferences, such as this upcoming workshop on ticks and tick-borne diseases.

Consider: without the basic knowledge inherent in getting a license, how can you be sure that staff are aware of the laws that keep incidents such as this from occurring? Who will be qualified to choose a pest management contractor when the need to protect students from the threat of pests — whether increased risk of asthma from mice or cockroaches, rashes from poison ivy, or anaphylactic shock from a wasp sting — relies on an expert’s help? And how will school personnel know what steps they can take to not only deal with existing (and potentially costly) pest issues, but also prevent new ones from taking place?

Answer: Be sure your maintenance staff gets the education needed to stay up to date with the latest pest management information.

“How To” …Our IPM Tools for Managing School Pests

The IPM Resources menu on the Best Management Practices for School IPM website provides ‘tools’ to help practitioners, experienced or new, practice IPM. And that’s the point.

Integrated Pest Management uses science- based knowledge to reduce pest problems. But as good as your practices might be, communication between custodians, groundskeepers, school staff, teachers and administrators, as well as the school board, and greater community is crucial. As with students, pest management works best when everyone is ‘on board’.

From our experiences in schools, and discussions with school staff and pesticide control officers, we created a list of resources to help in the everyday practice and that important cooperative effort.
