How to Identify Cockroaches Infesting your Electronics

If you’re seeing some roach activity, around your electronics, it is safe to assume that it’s a German cockroach.

This can easily be confirmed by looking at their distinct appearance while all cockroaches share some of the same characteristics.

The German cockroaches are easily identified by their size. German roaches typically measure only half an inch in length.

They’re lighter in color and they have two distinct dart lines behind their heads that run down their backs.

If you’re seeing other varieties of cockroaches in, or around your home, check out our guides on how to identify the various types of cockroaches.

However, our roach study so far shows that 78% of cockroaches most likely to infest your electronics are German roaches.

Now that you can properly identify German cockroaches, you need to inspect your home or property for further signs of activity.


Signs of Cockroach Infestations in Electronics

Check the areas around openings or ports, your device may have such as vents or battery ports.

If intended by the manufacturer open your device up for complete inspection. Ensure not to damage any of your inner components.

Now, it is possible that if your electronic device stopped working and you haven’t seen roach activity, then it could just be normal wear and tear or power surge.

So when you’re doing a roach inspection, you’re actually looking for not only the roaches but the signs of their activity.

What you should note are:

Roach droppings: Droppings will resemble, specks of black pepper or dark smudges and smears.

Egg casings: Egg casings will look a little like brown capsules.

Once you’ve confirmed German cockroach activity in your electronics, you can begin treatment.

Always note Safety first, before applying any pesticides, always wear your personal protective equipment.


How to Get Rid of Cockroaches in Electronics

Below is the step-by-step guide on how to get rid of cockroaches in electronics.


Applying Apex Cockroach Jailbait:

Apex is slow, killing bait. When roaches feed on it, they have time to return to the nest and spread the lethal bait to others.

This creates a cascading effect, wiping out other roaches and eliminating the colony before we make our bait placements.

It’s important to first clean your home or property to ensure that there are no competing food sources. Oftentimes, these roaches are forging leftover foods, oils, and other materials around the property.

Addressing that is very important. Also, ensure that when you clean, use only warm water and mild soap as chemicals, and typical household cleaners can deter roaches from bait placements.


How to Apply Apex Cockroach Jailbait

To apply this bait, drop it onto something like an index or business card and place this near the infested device.

You are doing this for two reasons:

  1. It just makes cleanup much easier.
  2. It makes bait placements, near where we know there is roach activity so that they are discouraged from forging, a way to other food sources that you might have missed.

During the cleanup, ensure that there are no other roach colonies around the property. You are also going to apply Apex in areas that roaches tend to forage.

This would be kitchens and bathrooms, place small baits inside cabinets, underneath appliances, and around the plumbing.

You’ll see a reduction in roach activity and about 3 to 5 days. Replenish the bait every 1 to 2 weeks until roach activity has stopped.

Once you have noticed a drop in roach activity, it will then use a residual spray to target any of the stragglers.


Apply Novacide Aerosol

Novacide is an aerosol insecticide that is labeled to control and not just German cockroaches, but other common pests like fleas, ticks, ants, and more.

Novacide is great to use because not only will it get rid of the adult German cockroaches, but will also target the younger generations.

It has a built-in insect growth regulator or IGR which will disrupt the life cycle and reproductive abilities of roaches. This will prevent eggs from hatching and younger nymphs from turning into adults.


How to Apply Novacide Aerosol

  1. You are going to hold the can upside down about 36 inches from the floor.
  2. Apply it in a sweeping position, covering about a hundred square feet.
  3. Focus on areas, around your electronics and kitchens.
  4. Spray around baseboards and around the internal perimeter of your home.
  5. Ensure you keep all pets and people off the treated areas until dry.
  6. For long residue effects, apply Novacide on materials like carpet, hardwood, linoleum tile, and ceramic tile, If there are any cockroaches remaining, they’ll crawl through the Novacide and eventually die.


How to Prevent Cockroaches in Electronics

Once you’re sure the roach activity has been eliminated from your electronics, going to need to give it a thorough cleaning, unplug or disconnect the device from its power source.

  1. Use a screwdriver to open it up and remove all eggs and fecal matter from the device.
  2. We don’t recommend using water or liquid cleaner, instead use a brush, a soft cloth, or a Q-tip.
  3. Ensure you’re not avoiding any manufacturer warranties by opening up the device.
  4. More prevention steps would be to make sure your home or property is clean.
  5. Ensure to sweep up any food crumbs.
  6. Remove excess moisture and clean any oils or grease off the stovetops, and countertops.
  7. Finally, be sure to follow up with preventive applications of Apex jailbaits and Novacide aerosol at least every 3 to 6 months.



In conclusion, cockroaches can pose severe damages to electronics if not eliminated, costing time and money.

However, going through this DIY guide on how to get rid of cockroaches in electronics, with a follow-up attempt. You’ll be able to control a cockroach’s infestation in electronics.
