Before knowing how to get rid of firebrats, identification is crucial.

  • Since firebrats and silverfish have similar appearances, they are frequently misidentified. While silverfish have a shiny silvery grey appearance, firebrats are often brownish to grey in color with a mottled pattern.
  • In addition, the firebrat’s body is more robust than the silverfish’s, which is more tapered.
  • Firebrats are little, wingless bugs that usually reach a maximum length of half an inch.
  • These insects are tiny, oblong-shaped, and have six legs, three long tail appendages, and two long antennae.

Step 2: How To Inspect For the Firebrats (Inspection)

Examine each room’s roof inside for any potential leaks. Examine the furnace, water heater, washing machine, dryer, and utility rooms for any leaks and dampness. Move yard debris outside to check for any sections of the grass that are wet.

In places that are nearly 100 degrees Fahrenheit and gloomy and humid, firebrats can be seen huddled together or congregating. If these pests are found in colder climates, silverfish infestations could be the cause.

Typical places to check for firebrats are in a hot attic, along steam lines, or behind or underneath large appliances such as the boiler, clothes dryer, oven, or water heater.

These pests typically, though not always, like to build their nests close to food supplies, so check any pantry items and paper goods that are kept for indications of infestation.

Outdoors, check yard garbage, leaf litter, woodpiles, stones, bricks, mulch beds, and in your lawn. Examine the plumbing, outside faucets, and area next to the air conditioner. If you own one, examine the crawl space.


Step 3: How To Get Rid of Firebrats (Control)

  • Apply D-Fense Dust:

After you’re done spraying, go inside and use D-Fense Dust to seal any cracks and crevices. An insecticidal dust containing deltamethrin is called D-Fense Dust. Because of its moisture resistance, this product is ideal for use in areas where firebrats may be present.

This solution should be used to treat deep into any cracks and crevices around areas where you have observed firebrat activity or harborages that are hidden from view, such as behind large appliances, behind wall outlets, beneath baseboards or flooring, and inside wall voids near plumbing and electrical.

It is advised that you use a portable duster to apply D-Fense Dust. You can apply this product deeper into areas that are difficult for you to look into with the aid of a duster.

Apply the substance using a duster at the recommended rate of two to three grams per square yard, or half a pound for every 1,000 square feet of treated area.

To dispense the dust, simply place the duster’s opening inside the area you wish to treat and press the bulb.

Upon coming into contact with or consuming this product, labelled pests—including firebrats—will perish in a matter of hours.

  • Apply Supreme IT:

Apply a long-lasting residual insecticide, such as Supreme IT Insecticide, outside first. This product is an excellent insecticide that will eradicate, deter, and stop firebrats and seventy other kinds of pests from ever entering your property.

Additionally, it will have long-term effects that might persist for up to ninety days, known as residual effects.

As this product must be mixed with water before application, we advise using a handheld pump sprayer to apply your solution for ease of mixing and spraying.

For every 1,000 square feet, combine 0.33 to 1 ounce of Supreme IT insecticide with one gallon of water.

You’ll treat the perimeter barrier surrounding your building’s base. Start by spraying any openings that firebrats could utilize to enter, such as doors, windows, and other gaps. Next, spray three feet up and three feet out along the outer perimeter of your building.

Step 4: How To Prevent the Firebrats (Prevention)

After knowing how to get rid of Firebrats, prevention is the next big step

  • Begin by caulking and shutting off any external (as well as internal) openings that might allow entry into your house. Seal any tiny cracks and crevices that could be letting Firebrats inside with caulk or copper mesh.
    Larger voids or gaps that must stay unsealed, like weep holes, may need to be filled with copper mesh. Small cracks and crevices can be sealed with caulk.
  • Put open or loose goods like flour, cereal, or rice into airtight containers to cut off the firebrats’ main sources of sustenance. Firebrats are more likely to stay outside where they belong when they have limited access to food.
  • You can reduce the warmth and humidity in your home by using air conditioning, fans, and dehumidifiers, as firebrats enjoy hot, dry, humid harborages.
    To cut down on the water source for firebrats, you can also find and fix any leaky pipes that may be present in your house. Use a dehumidifier if needed in basements and attics without ventilation.
  • Lastly, remember to apply your chemical products at the appropriate intervals.
    For maximum effectiveness, D-Fense Dust needs to be changed every eight months, and Supreme IT Insecticide needs to be administered every three months.
