About Bed Bugs

What Are Bed Bugs?

Bed bugs are small, parasitic insects that feed on human blood, typically at night. They are flat, reddish-brown, and about the size of an apple seed. Bed bugs are expert hiders and reproduce quickly, which makes infestations hard to eliminate without professional help.

Signs of an infestation.

Red, itchy bites in a line or cluster

Bed bug bites are often found on areas of the body that are exposed during sleep, such as arms, neck, and legs. The bites may appear in a zigzag pattern or straight line, and can be intensely itchy or inflamed.

Blood stains on sheets

Tiny rust-coloured spots may appear on your sheets or pillowcases. These are usually the result of accidentally crushing a bed bug after it has fed, leaving behind a small blood smear.

Tiny dark spots (droppings)

Bed bug droppings look like small black or brown dots, often found in mattress seams, furniture joints, or behind headboards. These faecal spots can bleed into fabric like a felt-tip pen.

Shed skins or eggshells

As bed bugs grow, they shed their exoskeletons. You might notice translucent shells in areas where they hide. Small white eggs or eggshells may also be visible in mattress crevices or baseboards.

Why DIY often fails.

Bed bugs are resistant to many store-bought treatments

Over time, bed bugs have developed resistance to many chemical sprays commonly found in retail pest control products. These treatments often fail to kill the entire population, especially more resilient bugs or those in hidden areas.

They hide in microscopic cracks

Bed bugs are masters of concealment. They can slip into cracks as thin as a credit card edge and hide deep within furniture, behind baseboards, and inside wall voids—places store-bought sprays can’t reach effectively.

You may kill visible bugs, but not eggs or hidden clusters

DIY treatments typically target only the bugs you can see. Unfortunately, eggs and deeply hidden clusters remain untouched, allowing the infestation to resurge weeks later. Professional heat treatment is the only reliable method for penetrating those protected zones.
