# 3. Check the inspection jar for any bugs

If **no bugs** are visible, simply [clean the cassette before re-inserting](https://guide.valpashotels.com/resolving-a-prevention-task/5.-clean-the-cassette-and-re-insert-it-into-the-smart-leg) it back into the leg.

Inspection of the contents is easier when the inspection jar is placed on a white surface, such as a paper towel or other light-coloured material.

**Bed bugs have distinct characteristics that help with identification:**

* Flat body shape
* Brown or reddish-brown color
* Six legs and two antennae
* Adult bed bugs are typically 5–7 mm long
* Younger bed bugs (nymphs) can be as small as 1.5 mm

If you discover any bed bugs, it's important to conduct a [room inspection](https://guide.valpashotels.com/bed-bug-found-room-inspection-needed) to prevent the spread of the infestation.

## Other findings

**Most common findings:**

* **Dust:** In some cases, excessive dust in the cassette can trigger a prevention notification.
* **Other insects:** Non-bed bug insects may also be found inside the cassette.
