02-02-2012 16:51 The University of Nebraska-Lincoln is dealing with a bedbug problem in its student dormitories, but it's not the only campus with the problem. The University of Nebraska-Omaha also dealt with the issue early in the fall semester.

UNO Deals With Isolated Bedbug Incident - Video

The bedbug problems at UNL should help us realize that the pest can show up anywhere. A UNL extension educator offers advice on getting rid of bedbugs.

Bedbugs. Just saying the word is enough to make anyone's skin crawl. The one-fourth- inch long reddish brown insect likes to come out at night and feed on your blood while you are sleeping.

To make matters worse, getting rid of them can be tough and expensive. However, if proper measures are taken at the first sign of bedbugs, managing the problem can be successful.

"This is a problem in our society that is not going to go away anytime soon," said Barb Ogg, University of Nebraska-Lincoln Extension Educator in Lancaster County. "Education is key because detecting them early is helpful in getting them under control as quickly as possible. Infestations that go undetected for longer periods of time will be harder to control and, in the meantime, can spread to other locations."

Ogg recommends a few simple steps to prevent and control bedbug problems:

-- When traveling, inspect hotel and guest rooms. Check cracks and crevices where bedbugs are most likely to hide during the day and areas around the mattress and headboard.

-- Don't place luggage on the floor. Use a luggage rack instead to keep items out of bedbugs' path.

-- If you find bedbugs when traveling, ask for a different room far away from the infested one.

-- If you believe you may have encountered bedbugs when traveling, take precautions when you get home to prevent bringing bedbugs into your home.

-- Do not bring your luggage inside, but unpack outdoors. Run all clothing through the dryer for 30 minutes on medium to hot heat. Inspect toiletries carefully before bringing them inside. Inspect and vacuum luggage or use heat or cold temperatures to kill bedbugs. Bedbugs die at 120 to 130 degrees F almost instantly. Freezing them is harder, but some studies have shown they die at 23 degrees F when maintained for five days.

To get rid of bedbugs most efficiently, it is helpful to hire a pest control company that uses the proper products and application tools, Ogg said. Professional treatment may be costly but is more likely to eliminate the problem.

Bedbugs have been around for thousands of years, Ogg said. Many scientists believe the insects long ago originated from bat-bugs that inhabited caves with early man. Over time, the wingless creatures adapted to feeding on humans who eventually transported them across the globe.

After the end of World War II, long-lasting insecticides were used to virtually eliminate the pest from homes in the U.S., Ogg said. However, for over the last 20 years bedbugs have resurged, making news most recently from showing up in posh hotels in New York City to apartments and college dorm rooms across the country, including UNL.

"There is no boundary to where a bedbug will or won't go," Ogg said.

Bedbugs hide in cracks and crevices of mattresses, box springs, sofas and chairs. Females can lay one to seven eggs a day, and the white eggs about the size of a pin head can be difficult to see.

Usually people don't know they have a problem with bedbugs until after they have been bitten, Ogg said. The nocturnal bugs crawl out of hiding places and feed on sleeping humans. The bite is painless but the result for most people is red, swollen, blotchy skin that will itch for several days. Another factor making bedbugs difficult to detect is that about 20 percent of the population doesn't react to the bites, she said. In addition, some people do not react to bites until several days after being bitten.

It can be especially difficult to remove bedbugs in multiple unit buildings, such as hotels, apartments and dorms, where the bugs can be brought in by one person and affect nearly everyone, crawling from unit to unit.

Bedbugs usually don't move from place to place on their own. They usually are brought in. They can be picked up anywhere from a motel to a movie theater to someone's home. They can crawl into suitcases, backpacks or used furniture, and then be taken into homes or other buildings.

Ogg said she even saw a case where a begbug was hiding in a cell phone and another case where a bedbug was found in someone's wallet.

A bedbug's life cycle consists of five immature stages of growth and an adult stage, Ogg said. When food is abundant and temperatures are warm, a bedbug can reach adulthood in one month. However, if food is limited, they can go without food for three to six months.

During growth, bedbugs rely on blood as their only food source.

"They use heat-seeking thermal receptors to locate humans to feed on at night, as well as carbon dioxide we exhale," she said. "Bites most often occur on the neck, arms and shoulders but can be found other places as well. Bedbugs probably don't bite through nightwear, but only on bare skin."

Ogg said research has never shown bedbugs transmit disease or pose other serious health threats to humans. However, many people experience psychological stress and insomnia after dealing with bedbugs.

"The real problem comes with the 'ick factor' of being bitten at night," Ogg said. "Nobody wants to go to sleep with the thought that bugs will be feeding on them during the night."

During the day, bedbugs retreat to cracks and crevices or tight spaces close to the bed such as bed coverings, mattresses, springs or bed frames where females lay eggs, Ogg said.

"It can often take a couple months before bedbugs are noticed," Ogg said. "But with the warm, favorable conditions of a house and unlimited food (sleeping people), thousands of bedbugs can be produced in four to six months if no control actions are taken."

Bedbugs leave behind tarry black spots or smears. Although these spots are most commonly seen near the bed, they also can be found in other places near where bedbugs hide, Ogg said.

Because they live in small cracks, bedbugs can be hard to control with do-it-yourself techniques, Ogg said. In addition, research has shown that most bedbugs are resistant to most over-the-counter products. The good news is there are more effective commercial products available to pest control companies.

A Few Bedbug Reminders

Since the afternoon of Jan. 23, Amanda Wekesser has not been able to sleep in her own bed, have access to all of her clothes or complete her homework.

Wekesser is a Selleck Quadrangle resident assistant at the University of Nebraska-Lincoln whose room was infested with live bedbugs. And she said she wasn't allowed to tell her residents.

"It's not fair that I'd be asked to hide this from them," Wekesser said. "(My residents) could be at risk and not even know it, because Housing is trying to hide it."

"It's like the Iron Curtain," she said.

On Jan. 24, University Housing reported on its website that "a single dead bedbug was found" in the Selleck Quadrangle 8000 building.

But Wekesser said what transpired in her room was far from "dead."

When she came back from winter break for spring RA training on Jan. 6, she said she began noticing bites on her neck, shoulders, back, arms and legs.

"At first, I thought it was some sort of allergic reaction to the swimming pool," Wekesser said. "They started getting better after a couple of days and putting on calamine lotion. I didn't consider going over to the health center."

But some of the bites got to be so bad, she used green masking tape on her bites to prevent from scratching as she slept.

Two weeks later, Wekesser caught two tiny bugs crawling around her room. She killed the first on her futon and caught the second in a Styrofoam cup. Wekesser taped clear plastic wrap over the cup so the bug wouldn't escape.

She contacted Selleck residence director Corrine Gernhart via email on Jan. 23 about finding what she called "mites" in her room.

"Please contact facilities today and let them know about the bugs in your room," Gernhart wrote back. "With so many concerns with bugs lately, I'm guessing they will want to come look around your room and maybe spray the perimeter again."

Facilities confirmed the "mite" had all the traits of a baby bedbug and gave Wekesser a laundry card to thoroughly do her laundry, she said. She was moved to a temporary room on a different floor.

Brooks Exterminating Service did not come until Jan. 24, and Wekesser said only a few things were sprayed, not the entire room.

"They figured a heat treatment would be a better option," she said.

In the days leading up to the heat treatment scheduled for Jan. 28, Wekesser said she asked about holding a floor meeting or sending a letter to her residents. The answer was no.

She said her instructions were to tell her residents her room was under extensive repairs, and only if her residents asked her.

"So I wrote it down briefly (on both of my doors) so I was doing what they said and so I could think about it," Wekesser said.

In an email, Gernhart wrote that she wouldn't recommend Wekesser sending a letter to her residents.

"If your residents are asking and you feel OK sharing, you can let them know that facilities is treating the room just to be cautious," Gernhart wrote.

But the deal was Wekesser could only inform her residents if she was asked directly.

Wekesser said on Jan. 25 she wrote on both her temporary and original rooms' doors that her room had been confirmed: It had bedbugs.

She also posted a note on her group's private Facebook page and slipped notes under a few of her residents' doors.

"I am not dirty or nasty," she wrote on her doors. "I feel that y'all should know about the situation though. I would want to know what was going on if I were in your position."

Wekesser only left the notes on the board long enough for her residents to see them and before a Housing employee could notice the notes.

"I'm willing to lose my job if need be, because this isn't right for them to not let the truth be known," Wekesser said. "I don't think it's right."

On Jan. 27, Gernhart sent a draft email to Wekesser, Residence Life associate director Keith Zaborowski and two others. The email told Wekesser's residents that "one dead bed bug was found" in Wekesser's room and a heat treatment would occur the next morning.

Gernhart wrote that the email needed to be sent because "I don't want them to think we are hiding anything from them when they notice the team on Saturday morning."
