First up is the most commonly recommended tool by far: rubbing alcohol diluted in water. This is suggested because alcohol can kill bed bugs on contact, and evaporates shortly after, so it’s considered safe for use pretty much anywhere in a home. A recurring theme in these recommendations are household items that are considered to be safer for people than mainstream chemicals.
If all other options have been exhausted, you may need to seek a professional PMP (Pest Management Professional). There are pesticides that are approved for professionals to use during a infestation. These pesticides, however, are not always effective, and typically not as effective as steam cleaning, excessive heat, or excessive cold. The exterminator may opt to treat the area with carbon dioxide.
Bedbug bites may go unnoticed or be mistaken for flea or mosquito bites or other types of rash or skin conditions, since the signs of bedbug bites are difficult to distinguish from other bites or skin conditions. Bedbugs also have glands whose secretions may leave musty odors, and they also may leave dark fecal spots on bed sheets and around places where they hide (in crevices or protected areas around the bed or anywhere in the room).
As for traps, these capture methods may not be full-proof for all bedbug species. Researchers have found that while both the common and tropical bedbug species have hairy feet, C. hemipterushas denser foot hairs, making this tropical insect an expert climber on slick surfaces. In the study, detailed on March 15, 2017, in the Journal of Economic Entomology, the researchers found that adult tropical bedbugs were much better at escaping traditional pitfall traps, which held onto most of the common bedbugs in the study.
The best bed bug traps are those that are used under the bed. The Climb-Up Bed Bug Interceptor is placed below the bed frame rollers or legs. The Climb-Up prevents bed bugs from being able to crawl either from the bed to the floor or from the floor to the bed. The Climb-Up works very well at isolating the bed from the floor and making it bed bug proof. As long as the comforter or some other linen is not touching the floor, then the bed is protected.
Bag and launder (122°F/50ºC minimum) affected items. Smaller items that cannot be laundered can sometimes be de-infested by heating. Individual items, for example, can be wrapped in plastic and placed in a hot, sunny location for at least a few days (the 122°F/50ºC minimum target temperature should be monitored in the center-most location with a thermometer). Bedbugs also succumb to cold temperatures below freezing, but the chilling period must be maintained for at least two weeks. Attempts to rid an entire home or apartment of bed bugs by raising or lowering the thermostat will be entirely unsuccessful.
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.
