These are the images captured from a townhouse in Toronto. This has been, so far, the highest level of Bed Bug infestation that we have successfully exterminated with only TWO application visits.

Please, note that all of these Pictures depict Scenes of a Very High Level of bed bug Infestation. Most infestation would not compare to this in terms of number of Bed Bugs, their Eggs, Skin Sheds and Feces (excrements).

Please, note that the residents had painted over the layers of Bed Bug feces. As well they had used Diatomaceous Earth in huge quantities to remedy and mask the problem.

The Window Sill Near Head Board:

These are hundreds if not thousands of black dot like excrements produced by bed bugs. The person living in the apartment tried to clean away this mess but did not address bed bug problem itself in any meaningful way. When you see bed bugs nesting beyond a bed’s components it should be obvious that the infestation among the bed components has reached full capacity provided by the nesting opportunities there.

There has been a poor attempt at painting over the blackened wall. Still you see huge number of Bed Bug excrements in the window sill.

Moving beyond a bed’s components, bed bugs would happily nest in

  • the curtains where they are mostly still and unmoved and changed

  • night tables or bed side tables

  • other wooden or wicker furniture objects near the bed.

The Walls and the Baseboards:

This scene is just below the window sill image presented above.

Painting over tons of Excrements was futile!

There has been a poor attempt at painting over the blackened wall and baseboards.

While Bed Bugs are not social insects and do not make large social nests, when there is a multitude of them, then, their presence feels like that you have arrived inside of their nest.

We see several hundreds of dead Bed Bugs on the carpet. There is also Diatomaceous Earth dust on the carpet. Painting and Diatomaceous Earth would cause some discomfort to Bed Bugs but these efforts are fruitless.

Overcrowded Bed Bugs:

So far away from the host and under no cover from any light!

Why would Bed Bug choose such a spot?

This is one the factor that we weighed in to declare this to be the worst case of Bed Bug infestation that we provided extermination services for.

If you look closely in the corner:

  • Large layer of black excrements has developed in the corner.

  • A smaller translucent white layer of Eggs is developed on top of the black one.

Bed Bug Friendly Sofa Bed Frame:

This image is representative of what is ground zero. Bed Bugs must have been compelled to move away from this comfortable wooden frame just because of overcrowding. You see that in areas of greater affinity there are layers of black excrements and in other spots there are piles of white shiny translucent bed bug eggs.

The Bed Bug Notoriety of Electrical Sockets:

Sometimes electrical sockets are presented as a possible nesting spot to sensationalize the situation however in this case of extra ordinary infestation it is just obvious that any spot is good spot.

Bed Bugs would only be compelled to nest in the Electrical Sockets when the infestation is well established and typical spots are overcrowded for bed bugs to nest in. And of course the location of the Electrical Socket just near the head board of the bed is close to an ideal.

Of course, for a typical bed bug infestation Electrical sockets located on the end of the room practically do not matter.

In case of a heavy infestation, bed bugs would happily nest in

  • Folds in the sheets and coverings of bed components

  • At the edges and piping of pillows and cushions

  • Peeling wallpaper, gaps by baseboards, unusually large cracks in floorings, etc.


Just like the Electrical Socket, when such spots, that provide recessed areas of shelter for Bed Bugs to creep into, exist near a bed, they become a great potential nesting spots.

This poster was put on by the top edge of the wall and ceiling. It is the curled up edges of such paper coverings that provide Bed Bugs the perfect spots to sneak under. In the corner you can see layers of white shiny eggs laid over layers of black excrements.

Bed Bugs Excrements on Ceiling!

Being a bed bug exterminator, I do not come across this often that I see bed bug nests on ceilings.

In this image there are black dots that are the faces and  skin shed.

This location on the ceiling does not provide any shelter from lights and it is quite a distance from the bed where the host might be found.

Also, the abundance of Bed Bugs were feeding a decent population of Spiders.

These factors made us consider this to be the worst case of Bed Bug infestation that we had to exterminate in Toronto. Click the Image for full resolution.

What makes this scene unusual because bed bugs nest:

  • The distance from a host is unusually far.

  • This spot is not having a cover from light. This is very unusual.

  • The only advantage is not overcrowding in the usual nesting places in a bed.

3 Important Sights

1st Sign
1st SignBlack Feces
When looking for signs of bed bug presence in a bed, you are likely to find these first. So to overlook these and not focus on what should you be looking for is a terrible mistake. These black marks feel extruded on surfaces where they are not absorbed completely. When these are left near piping of mattress and box spring’s fabric surface, this bursts into the fabric fibres just as ink would!
2nd sign
2nd signSkin Shed
Bed Bugs molt (grow bigger and out of their skin) 5 times during their development from a baby (nymph) to a full size adult. So for every developing bed bug, as time passes by there will be these evidence of their presence. Skin sheds are usually found near where bed bugs nest but not necessarily.
3rd sign
3rd signWhite Eggs
Bed Bug eggs are very small in size. In appearance these are white and translucent. Unless you have good lighting conditions, these would be hard to see unless on a darker matte background. Bed Bug eggs are always present in established infestations but them being the 3rd obvious sign is because of their size and likelihood of being noticed.
