9/22/2011 How Texas Wildfires Have Fueled Bedbugs
With many Texans displaced by recent wildfires, bed bugs may become another unwanted irritation during relocation, said Texas AgriLife Extension Service and Texas AgriLife Research experts.
“With so many people being displaced and having to find accommodations in hotels or motels, it’s important for them to be aware of the possibility of encountering bed bugs and to know something about their behavior and biology,” said Wizzie Brown, AgriLife Extension integrated pest management specialist in Travis County.
Brown said bed bugs have been a growing problem throughout the U.S. and beyond, especially in urban areas with a large volume of visitors.
And national media have noted complaints of bed bugs by people in accommodations ranging from low-end motels to five-star hotels.
“However, I also get calls from student housing on campus, people in apartments, in homes and other locations,” Brown said.
“It’s not just hotels or motels. People can even be exposed to bed bugs while staying in the home of a friend who doesn’t know they have them.”
Bed bugs often leave dried blood or rust-colored stains in mattresses, especially on the mattress folds and tufts, she said.
“When you get to your hotel or motel room, pull back the bedding to expose the mattress and box springs and check the mattress, especially the areas near the seams and tags,” Brown said. “It’s also a good idea to inspect the headboard as well as items near the bed, such as a lamp base or nightstand.”
While bed bugs, as their name implies, prefer beds and bedding, they also can be found under cushions, behind picture frames, near lamp stands, behind baseboards, in back of electrical switch plates and in other locations, she said.
Inspect the room where you plan to stay before bringing up your belongings, Brown suggested.
If there’s evidence of bed bugs upon a thorough room inspection, request a different room or, if possible, go to a different location.
“But the more hotels and motels you stay in, the greater the probability of being bitten by bed bugs,” said Dr. Roger Gold, urban and public health entomologist with AgriLife Research in College Station.
“They have really proliferated over the past several years throughout Texas and the rest of the U.S.”
Gold said newly hatched bed bugs are about the same size as a sesame seed, only flatter, and can hide in a variety of cracks, crevices, nooks and crannies.
A large adult bed bug, about the size of an apple seed, can be mistaken for a tick.
Brown and Gold said there are some steps travelers can take to protect themselves from these pests and reduce the risk of bringing them home.
The first is to have housekeeping vacuum thoroughly to remove as many bed bugs and their eggs from mattresses, box springs, carpets and other areas, concentrating particularly on mattress and box springs seams, tufts and edges, as well as where baseboards and carpet meet.
Entomologists say bed bugs are thought to locate their human hosts by body heat and the carbon dioxide exhaled during respiration, but some bed bugs may wander before they locate a host.
Therefore, people should take steps to reduce the risk of taking the pests home with them when they leave their temporary accommodations.
Since bed bugs crawl into cracks and crevices near the bed, they suggested keeping suitcases off the floor.
“Placing luggage in the bath tub may be an option since it has smooth sides and may be harder for bed bugs to access,” Brown noted.
“If there’s any positive at all to bed bug bites, it’s that they’re relatively painless,” Gold said. “Typically they’ll feed and be gone and you won’t even know it.”
However, about half of all people bitten have an allergic reaction to the saliva injected while bed bugs feed, Brown said.
“It’s the people with the allergic reaction who develop the welts,” she said. “This also explains why there have been many cases where people are unaware that they have bed bugs – because they aren’t reacting to the bite – as well as why one person develops welts while another in the same room doesn’t.”
