When you first discovered an infestation, you probably never thought you’d need to know how to get roaches out of electronics or appliances. Unfortunately, these are some of the most common nesting spots for these little nasties.

One common victim is your printer, which can easily malfunction from an infestation.

Why Roaches Are Attracted to Printers

There are a number of reasons why roaches would want to make their home in your printer, X-Box, dishwasher, fridge, or microwave.

Here are five factors that can lead to a case of printer insects:

  1. Printers generate heat when in use, creating an ideal environment.
  2. Printers often have small crevices and spaces that provide the perfect hiding spot for cockroaches.
  3. Roaches (and their cousins, termites) prefer a diet rich in cellulose, making printer paper a tasty feast.
  4. It’s common for a printer to be left unused for long periods of time, collecting dust and making a perfect nesting ground for bugs.
  5. Finally, it’s common to have a printer set up near your workspace where snacks or food can attract roaches.

Potential Damage From Roaches

Finding cockroaches in your printer or another electronic appliance is never a good sign.

Their frass can cause shorts in the circuits, and it’s not uncommon for them to nibble on wires. Even worse, one could get crushed while you’re printing, leading to an awful mess.

The sooner you identify and deal with a printer infestation, the less risk of damage.

How to Identify Roaches in Your Printer

If you suspect that your printer has become a haven for cockroaches, it’s important to identify the problem as soon as possible.

Here are some signs that your printer might be infested:

  • You see roaches scurrying out of your printer when you turn it on or off or when something starts printing.
  • You notice roach droppings or shed exoskeletons around or inside your printer.
  • Your printer is making strange noises or not functioning properly.

One way to confirm that you have a roach infestation in your printer is to use a flashlight to look inside the printer. Roaches are attracted to warm, dark spaces (which the inside of a printer qualifies as), especially near the fuser unit or toner cartridge.

If you’ve discovered cockroaches in your printer, don’t panic. There are several effective methods you can use to get rid of them.

#1 – Vacuum the Printer

The first step in removing roaches from your printer is to vacuum it thoroughly. Use a handheld vacuum or an attachment on your upright vacuum to carefully suction out any visible roaches, eggs, or droppings.

Pay special attention to the areas around the paper tray, ink cartridges, and other crevices where roaches might hide.

Be sure to dispose of the vacuum bag or canister immediately after vacuuming to prevent any remaining roaches from escaping.

#2 – Roach Bait and Traps

Another good way to get rid of roaches in your printer is to use roach bait and traps.

Place bait stations near your printer and use sticky traps to catch any types of roaches that venture out. Be sure to check the traps and replace the bait regularly until all the roaches are gone.

Keep in mind that these traps can take several days or even weeks to be fully effective.

#3 – Clean With Alcohol or Vinegar

Once you’ve removed any visible roaches, use rubbing alcohol to kill any remaining roaches and sanitize the printer. Unplug the printer, then, mix equal parts rubbing alcohol and water in a spray bottle and spray the solution onto a cloth.

Use the damp cloth to wipe down the printer, paying special attention to the areas where roaches were present. Make sure the printer has completely dried before turning it back on for use.

Keeping Roaches Out of Your Printer

Tip 1: Store Printer in a Closed Cabinet

One of the most effective ways to keep roaches out of your printer is to store it in a cabinet. Unless there are small entry points, this will usually prevent roaches from getting inside and making a home in your printer.

Tip 2: Keep Printer Clean and Free of Crumbs

Roaches are attracted to food crumbs and debris, so it’s important to keep your printer (and the area around it) clean and free of any food particles.

Wipe down your printer regularly with a damp cloth to remove any dust or debris. Avoid eating near your printer and make sure to clean up any food spills or crumbs immediately.

You can also use a vacuum to suck up any debris or dust that may have accumulated inside your printer. Make sure to use a soft brush attachment to avoid damaging any delicate parts.

Tip 3: Use Roach Repellents in Your Printer Area

Roach repellents can be a good way to keep roaches away from your printer. You can use natural repellents like peppermint oil or vinegar, or commercial roach repellent sprays or baits.

When using roach repellents, make sure to follow the instructions carefully and keep them away from any food or drinks.

You should also avoid spraying or applying repellents directly onto your printer, as this could damage the printer or cause it to malfunction.
