Bed bug infestations are notoriously difficult to kill off because they often dwell in nooks and crannies such as bed frames, mattresses and behind pictures. Bed bugs do not pose a threat to your health but their bites can be itchy. If you have an allergic reaction to the bites, they can be very itchy and may cause painful swelling.
One trial also suggested that freezing can be used to decontaminate infested clothing, noted the review.
“However, because bed bugs can survive for up to one year without feeding, keeping an infested room vacant is not an effective option,” the research said.
It added: “Disposal of highly infested items, together with physical removal of bed bugs and mattress covers and vacuuming, are recommended by pest managers’ codes of practice, even though scientific evidence of their efficacy is lacking.”
The other option is to call in a professional exterminator.
“Some professional exterminators use portable devices to raise the temperature of a room to a lethal temperature,” explains Mayo Clinic.
According to the health body, all stages of bedbugs can be killed at 50 degrees Celsius.
