Chicago Ranked Tops for Bed Bugs and Loyola Physician Explains Why

A national pest control company says it did more business in Chicago for bed bugs last year, than any other city. But one Chicago doctor isn't biting. "As a major city with a large, diverse population and many international visitors, Chicago does have its bed bug problems but I still tend to think New York ranks higher," says Joseph Leija, MD, who performs the Gottlieb Allergy Count for Loyola University Health System. New York was ranked 10th on the list.

Leija does readily admit that he has treated his share of patients who came in complaining of itching. “A family came in covered in bedbug bites from infested ‘free’ furniture they found in an abandoned apartment,” says Leija.

“The couple had only taken the wooden headboards and baseboards of the beds – not the mattresses because they knew that would be unsanitary – as well as a table and chairs. The bugs were found in the tiny crevices,” he says. Leija has also cared for patients with bedbug bites traced back to clothing purchased at neighborhood garage sales and resale stores.

“Bedbugs are insidious survivors who travel well – they hide in cracks in wood and in the weave of cloth,” says Leija of the parasite known scientifically as Cimex lectularius. “They are vampires – they are dormant during the day but come out at night and feed on human blood.”

Bedbugs have a set of pinchers: they use one to pierce the skin and inject saliva which contains anticoagulants and a numbing solution, while the other pincher sucks the blood of its host, Leija says. “The male bedbug also uses the pincher to pierce the abdomen of the female during reproduction, and bedbugs reproduce rapidly."

Bedbugs find their prey by seeking carbon dioxide or warmth, to indicate a warm-blooded animal.

“The bites can result in a skin rash or even large weeping blisters due to allergic reaction,” says Leija. “But for many, the psychological damage is greater than what they suffer physically.”

Here are Leija’s top five tips to maintaining the upper hand on bedbugs:

• If you buy used clothing, keep them in the plastic bag before washing immediately in hot water. “Use the dryer at high heat to make sure all parasites are killed,” says Leija.

• Paint or seal any newly acquired used furniture. “Bedbugs are so tiny they have been known to hide in screwholes,” says Leija.

• Spray insecticide and vacuum bedding and furniture thoroughly and throw the vacuum cleaner bag outside in the trash after each sweeping. “Keep spraying the insecticide and vacuuming daily; check for tiny brown bugs or pieces that may be part of the bug,” says Leija.

• As you travel this holiday, check the mattress before bedding down. ‘If you see tiny brown specks, move yourself and your clothing and your luggage out immediately,” says Leija. “And tell the hotel manager or your hosts what you have discovered to prevent further infiltration.”

• If you are bitten by a bedbug, Leija recommends, “Wash the area carefully with soap and water, drying thoroughly. Apply anti-itch cream, such as calamine lotion, to prevent irritation and limit scratching.” If the bite area becomes warm to the touch, swells or hurts, go to the doctor for prescription medication.
