Cockroaches are unwelcome guests in any home, and they can be particularly troublesome when they infest your computer. These pests are attracted to the warmth and darkness that computers provide, making them an ideal habitat. Not only are they a nuisance, but they can also cause significant damage to your device. If you’re dealing with this issue, you’re probably wondering how to get roaches out of a computer. This comprehensive guide will walk you through the process step by step, providing practical solutions and preventative measures.


To get roaches out of a computer, first, turn off and unplug your computer. Move it to a well-ventilated area and use a can of compressed air to dislodge the roaches. Set up bait traps around the computer to catch any remaining roaches. Once all roaches are removed, clean your computer thoroughly and monitor the situation for signs of re-infestation. To prevent future infestations, keep your computer elevated, use roach traps, seal any large openings, maintain cleanliness, and use natural repellents.

Signs of a Roach Infestation in a Computer

Before we delve into the solutions, it’s crucial to understand the signs of a roach infestation in a computer. These include:

  • Roach droppings: These resemble black pepper and are usually scattered around the power supply or wire ports of your computer.
  • Deceased roaches: Finding dead roaches in or around your computer is a clear sign of infestation.
  • Unpleasant odor: Roaches produce a musty or oily odor, which may be noticeable if they’ve infested your computer.
  • Egg cases: If you find roach egg cases inside or near your computer, it’s a sign of infestation.
  • Allergy symptoms: Roach infestations can cause new allergy symptoms in some individuals.

Steps to Remove Roaches from Your Computer

Once you’ve confirmed the infestation, it’s time to take action. Here’s a step-by-step guide on how to get roaches out of a computer:

  1. Turn off and unplug the computer: This is the first step to ensure your safety and prevent any electrical damage.
  2. Move the computer to a well-ventilated area: This will help you work on the computer without spreading the infestation to other areas of your home.
  3. Use pressurized air: Use a can of compressed air or a blower to dislodge and remove the roaches from your computer. Be careful not to damage any internal components while doing this.
  4. Set up bait traps: Place sticky or poisoned bait traps around your computer to lure the roaches out of the case and trap them. For example, you can use the Victor M330 Roach Pheromone Glue Trap.
  5. Clean the computer: Once you’ve removed the roaches, clean the computer thoroughly. Use a soft brush or cloth to remove any debris, and use compressed air to clean hard-to-reach areas.
  6. Monitor the situation: Keep an eye on your computer for any signs of re-infestation. If the problem persists, consider calling a professional exterminator to help you deal with the issue.

Preventing Future Infestations

After you’ve successfully removed the roaches from your computer, it’s crucial to take measures to prevent future infestations. Here’s how:

  • Keep the computer elevated: Place your computer on a table or a stand to minimize the chances of roaches crawling into it.
  • Use roach traps: Place roach traps around your computer and inside the PC case if possible.
  • Seal openings: Cover any large openings or vents in your computer case with mesh filters or cut-to-fit Swiffer pads to prevent roaches from entering.
  • Maintain cleanliness: Keep the area around your computer clean and avoid leaving food or drinks nearby.
  • Use natural repellents: Apply natural repellents like diatomaceous earth or boric acid around your computer, but be cautious not to let them come into contact with the electronic components.

Safety Precautions

When dealing with roaches, it’s essential to take precautions to prevent harm to your computer and yourself. Remember to wash your hands thoroughly after handling any roach-infested items or areas to prevent the spread of germs and diseases. Avoid eating near your computer, as this can attract roaches due to the presence of food particles. Lastly, consider hiring a professional pest control service if the infestation is severe.

In conclusion, roaches in your computer can be a significant problem, but it’s one that can be solved with patience and the right steps. By following the advice in this guide, you can effectively get rid of roaches in your computer and prevent future infestations.
