Insecticide Application This is the most common way to get rid of bedbugs, Lazarus says. Oftentimes, the professional will use several different products to effectively treat the area, though it may take a few rounds to ensure removal. “The advantage to this method is that the residual insecticide will continue to offer protection for a period of time,” Lazarus says. “The biggest drawback is that the preparation for service is time-consuming and must be repeated prior to each service.”
Bed bugs are highly vulnerable to heat; exposing them to a certain amount of direct heat will kill them instantly, while lower temperatures can kill them in a matter of minutes. This is why many forms of heat treatments are recommended. Some methods, such as steamers and portable heaters, have been proven effective through professional use and are quickly becoming standard issue in holistic treatment arsenals.
The decline of bed bug populations in the 20th century is often credited to potent pesticides that had not previously been widely available. Other contributing factors that are less frequently mentioned in news reports are increased public awareness and slum clearance programs that combined pesticide use with steam disinfection, relocation of slum dwellers to new housing, and in some cases also follow-up inspections for several months after relocated tenants moved into their new housing.
Bedbugs normally feed at night, usually approximately 1 hour before dawn. However, if the conditions are favorable, they also feed during the day. Feeding takes 3-12 minutes. In proper conditions, adult bedbugs can survive without a meal for 1 year or longer. Each female lays approximately 300 eggs in her lifetime. The eggs hatch in 10 days. The nymph stage lasts 6 weeks, undergoing 5 molts.
According to textile experts (Drycleaning & Laundry Institute, Laurel, MD), most garments designated as ‘dry-clean only’ (e.g., cotton, wool, silk, linen, rayon, nylon) will not be harmed provided they are dry before being placed in a clothes dryer at a moderate temperature setting. Dry cleaning procedures also kill bed bugs, but there is a risk of infesting the establishment when buggy items are tagged and sorted.
Reactions to bed bug bites vary among individuals. Many persons show no signs of bites. Others don’t realize they’ve been bitten until redness and swelling appear around the bite, sometimes with intense itching. Some exhibit inflamed swollen spots that may occur in linear series or have a rash-like appearance. Such bite marks, when they appear, may not show for several days after the person is bitten.
