Don’t Bring Bed Bugs Back as Souvenirs

Friday, April 27th, 2012

Written by: Robin L. Tabuchi, Research Entomologist, University of California, Berkeley.

For many of us, summer vacation means spending time with family and friends, relaxing and travelling. Although I love travelling, there’s one pest I don’t look forward to sharing my vacation with; the infamous, blood-sucking bed bug! By now you’ve all heard of bed bugs, but you might not know how to avoid them.

Your bags are packed, the gas tank is full, and you’re ready to hit the road. Travelling can be quite an ordeal, and once you arrive at your destination, you’re tired and want to get settled in to your hotel room. Resist the temptation to unload everything from your car just yet. If you arrived by plane, either ask the hotel staff to bring your luggage up shortly, or take it with you and place it in the bathroom or non-carpeted entry. Now it’s time to inspect your room for bed bugs!

As with any pest, identifying it is the first step to protecting yourself and your belongings. Adult bed bugs are reddish-brown. Their bodies are oval and flattened, and they’re about the size of an apple seed. They don’t have wings, can’t jump, and only move by crawling. Bed bug nymphs are smaller in size and lighter than adults, but they look similar in appearance.

All bed bug nymphs and adults feed on blood. The nymphs need blood to molt and the adults need blood to mate and lay eggs. If a room has bed bugs, you’ll likely find fecal staining too (a.k.a. bed bug poop).  Fecal staining is light brown to black and looks like tiny drops of dried blood.

Bed bugs are very good at hiding and can fit into tiny cracks and crevices. Begin your inspection with the bed and headboard, because after all, they are called bed bugs! They like to stay somewhat close to their food source and typically feed at night. Pull the sheets back and check mattress seams for adults, nymphs or fecal staining. Slide a credit card between the top of the headboard and the wall or remove the headboard and peek behind it.

Search other upholstered furniture for signs of bed bugs and walk around the room looking for fecal staining on walls, other furniture items, and the luggage rack.

What happens if you find a bed bug? If you’re brave, capture a specimen or take a photo. Discuss what you found with the hotel management. Request a new room and then inspect that room too.

What should you do if you don’t find anything? Just because you didn’t find something doesn’t mean there aren’t bed bugs. Keep personal items and clothing in a designated area of the room away from the bed. Bag your dirty laundry within your suitcase. Once you return home, leave luggage outside or in the garage and unpack there. Inspect luggage for bed bugs and then wash and dry all of your clothing on the warmest setting.

Safe travels!

Trivia Thursday: How much do you REALLY know about poison ivy?

Thursday, April 26th, 2012

Rumors are always spiraling on how to ditch the poison ivy itch. How poison ivy savvy are you? Read below and find out!

Once a poison ivy plant dies, it is no longer toxic. True or False?

False. We all know this irritating plant can cause a rash and persistent itch, but not after the plant has died, right? Wrong. Urushiol, the oil from the poison ivy plants that causes the allergic reaction, can stay active on any surface for up to five years. These surfaces could include gardening tools, clothing and dead plants. So, how do you properly dispose of these plants or avoid contact with leftover plant oils? Here are a few tips:

  • Always wear gloves and handle the plants with great caution
  • Dispose of the plants in tightly sealed garbage bags
  • Clean all gardening tools with hot, soapy water or rubbing alcohol (or both!)
  • Wash clothes in hot water to prevent the poison ivy from spreading

The infamous rhyme “Leaves of three, let them be” is not always the case. True or False?

True. If only it were that easy! While this rhyme holds true for poison ivy, it’s not always 100 percent accurate for poison oak and poison sumac. These three plants are all species of the Anacardiaceae family and contain the same rash-causing substance, urushiol. They cause relatively similar symptoms and are even treated the same on most occasions. However, with the exception of this commonality, all three differ in how you can spot them in the landscape.

Most familiar is poison ivy with its three bright green leaves and a red stem. On the other hand, poison oak, can have three to five leaves, and poison sumac comes out on top with anywhere from seven to 13 leaves on a branch. So don’t narrow your caution to only leaves of three. Keep an eye out for other poisonous plants and avoid them, if at all possible!

Control Ticks to Control Lyme Disease

Long History and High Rates

Lyme disease doesn’t just occur at high rates in Connecticut – the disease was named after the Connecticut community of Lyme. Now, more than three decades since the cluster of disease sufferers in Lyme inspired the name, the disease continues affecting our state significantly. Connecticut experiences more Lyme disease cases relative to state population as any state in the country[i] with the Center for Disease Control and Prevention confirming nearly 2,000 cases in 2010, alone.[ii] The Connecticut Department of Public Health says the continue prevalence of Lyme disease is due partly to “increased tick abundance” and “increased potential for contact with ticks.”[iii]

People suffering from Lyme disease can experience facial or Bell’s palsy, severe headaches and neck stiffness, pain and swelling in large joints and heart palpitations and dizziness. However, Lyme disease is difficult to diagnose as its symptoms can be attributed to other health problems. Left untreated, approximately 60 percent of Lyme disease sufferers experience arthritis, while 5 percent develop chronic neurological challenges months or years after the infection.[iv]

More (Hungry) Ticks = More Lyme

Lyme disease is a concern for Connecticut any year, but 2012 may prove to be a banner season for ticks. Experts have identified various factors that may increase Lyme disease risk this spring and summer. Recent news reports outline several ecological events leading to the predicted increase in Lyme disease:

  • Foxnews.com reported on March 23 that ecologists are blaming a bumper acorn crop followed by a poor crop, which led to a white-footed mouse population surge and subsequent decline, for an increase in hungry ticks looking for a mammal on which to latch. [v]
  • The New York Times noted on March 18 that entomologists say the mild winter is leading to increased tick activity earlier than normal and increased the opportunity for people and ticks to come into contact.[vi]
  • Richard Ostfeld, a disease ecologist for the Cary Institute of Ecosystem Studies, says the warm weather and the lack of white-footed mice for hungry ticks to feed on, creates a perfect storm for an uptick in Lyme disease: hungry ticks, fewer food sources, and more active months to be on the prowl for a meal.[vii]

Important Tick-Fighting Tools

Controlling the tick population helps reduce the likelihood that unsuspecting athletes, campers, hikers, or anyone enjoying the outdoors will encounter hungry ticks. Thoughtful and careful use of pesticide products is an effective step in the process to protect Connecticut from more prevalent Lyme disease problems. The Connecticut Agricultural Experiment Station says pesticides that target ticks (acaricides) are the “most effective way to reduce ticks, particularly when combined with landscaping changes to decrease habitat.”[viii] One application of insecticide targeted at tick habitat (not broad spraying) provides 85 to 90 percent control of tick populations.[ix]
