Bed Bugs in Laptops and Electronics: Can They Hide There?

If you have bed bugs, you may worry about your laptop, phone, charger and other electronics. Bed bugs are drawn to warmth, and devices near the bed can be warm and have many small crevices. It is a reasonable concern, though real cases of infestations living inside electronics are uncommon.

This guide explains the risk and safe precautions.

The short answer

Bed bugs can hide on or in electronics, especially in crevices, vents, ports, cable bundles and cases, because devices are warm and often kept near beds, but they rarely live inside sealed electronics for long, and heavy colonies are uncommon. The main risk is that they hitchhike on devices to other rooms or homes. To protect your devices, inspect them, keep them away from the bed during an infestation, do not use insecticide sprays on electronics, and use safe methods such as careful inspection, vacuuming of exteriors and, if needed, professional heat treatment.

Why devices attract bed bugs

• They give off warmth.
• They sit on bedside tables, close to hosts.
• Vents, ports, hinges and cable bundles offer hiding places.
• Cases and bags provide folds and seams.

Where to check

1. Laptop vents, hinges and the underside.
2. Phone cases and charging ports.
3. Chargers, cables and power strips.
4. Bedside clocks, speakers and lamps.
5. Bags and sleeves used for carrying devices.

How to inspect

• Switch off and unplug the device.
• Use a flashlight and a magnifier or phone camera.
• Look for live bugs, dark spots and shed skins.
• Check the carrying case and the area around the device.

Safe ways to protect devices

1. Do not spray insecticide on or into electronics. It can damage them and leave residue.
2. Keep devices away from the bed during an infestation, ideally in sealed plastic bags or containers.
3. Vacuum exteriors and vents gently with a brush attachment.
4. Clean cases and bags by washing or heat-drying where possible.
5. Do not use high heat on devices yourself, as it can damage batteries and electronics.
6. Ask a professional about safe heat treatment of valuable or sensitive items.

Avoiding spread

Do not carry devices between infested and clean rooms without checking, and be careful when travelling, keeping devices in sealed bags and off beds and carpets.

When to call a professional

If you find bed bugs on or near electronics, treat the home. A technician can advise on handling devices.
