You might even be able to tell if you have an infestation due to the smell. 

“One of the strongest signs of a bedbug infestation is an unusual odour with no other obvious cause,” says The Mirror. “This is often described as a musty, sweet smell.” 

Dodson Pest Control explains: “Bed bugs can smell different to different people. Many people report smelling coriander, but another common description is the scent of spoiled raspberries.

“Others report a strong acidic scent or that of almonds or marzipan. If you notice an unusual smell in an otherwise clean room, it may be time to call in a professional.”

That said, here are some tips from Superintendent Pharmacist, Phil Day at Pharmacy2U on what you should know to keep yourself and your home safe.

How to identify bedbug bites

“Bedbug bites tend to be very itchy and uncomfortable, but they are not usually dangerous,” says Day.

Their Pattern

“Bedbug bites usually appear in a clustered or linear pattern in areas of exposed skin such as arms, legs, neck, and face.”

Their Appearance

Day explains bites resemble small, red welts or raised bumps: “On black or brown skin, they may look purple and may be harder to see.”

The Amount Of Itching

“Bedbug bites can be intensely itchy, and the itching may persist for several days.”

Nocturnal occurrence 

“Bedbugs are most active at night, so bites often occur while you’re sleeping.”
