Keith's Pro Tips

"It is important to apply Ficam Insect Bait at least 10 feet away from the perimeter where you applied Supreme IT. If you apply Ficam too close to the Supreme IT application, the roaches will not eat the bait. By placing it 10 feet away from the Supreme IT application they will be repelled back to where the Ficam is waiting which they will readily ingest."

Where To Inspect

Smoky Brown Cockroaches are usually found outside and are mainly found in humid, and moist areas. The smoky brown roach needs to be hydrated constantly, which is why it is usually found close to sources of water like poorly drained lawns, sewers, or inside yard debris.

Outside in the yard search around yard debris, like leaf litter, woodpiles, logs, rocks, stones, and areas where water does not drain. Also check inside rain gutters, buckets full of rainwater, and near leaky faucets.

Smoky Brown Cockroaches usually invade a home because the weather outside turns harsh, especially in the winter. They can also infest homes and buildings, because there are plenty of water sources nearby or standing water that is attracting them.

Look in kitchens, bathrooms, attics, and utility rooms. Look in all the areas where moisture is created such as underneath sinks. Indoors check inside pantries, cabinets, shelves, drawers, and in cracks and crevices that are usually undisturbed. Due to their strong ability to fly, they can also reach your homes attic or crawl spaces.

What To Look For

You're looking for smoky brown cockroaches and their activity. This includes finding feces (or droppings that look like black pepper) and the roaches themselves since they will eat theirs or other roaches feces.

Most smoky brown roaches will be found sources of water, so inspect the areas mentioned above. The areas most frequented by the smoky brown cockroaches will have signs of feces, shed skins, or sometimes will have a small, black egg sack since they like to lay their eggs near a source of water.

Smoky Brown Cockroaches will climb your trees or branches hanging over your home to gain access to your residence.

Step 1 - Outdoor Perimeter Treatment with Supreme IT Insecticide

Begin treatment outdoors, where most smoky brown cockroaches will be found. Supreme IT is a powerful insecticide that will both repel and kill smoky brown roaches from coming close to your property. Supreme IT also has a residual (or long-term effect) that will last for up to 90 days.

Determine how much Supreme IT you will need by calculating the square footage of the perimeter. To do this, measure and multiply the area length times the width (length x width = square footage). 1 ounce of Supreme IT can treat 1,000 sq. ft. So for example, if you calculated 2,500 sq. ft., you would need 2.5 oz. of Supreme IT mixed in 2.5 gallons of water.

Mix the appropriate measured amount of Supreme IT with the correct amount of water inside a pump sprayer. Perform the perimeter treatment by spraying 3 feet up and 3 feet out from the foundation of your home while also spraying windows, doors, garages, eaves, soffits, rain gutters, cracks and crevices, and electrical/plumbing penetrations.

Step 2 - Apply Ficam Insect Bait

As an added measure outdoors, apply Ficam Insect Bait. Ficam is a granular insect bait that mimics food, which the smoky brown roaches will ingest and eat until they die. You will apply by creating a perimeter treatment around your structure, making sure it is at least 10 feet away from the structure.

To apply, create a band of 2 to 4 feet at the rate of 6 ounces per 100 square feet. You can also apply Ficam around trees, flowerbeds, in mulched areas, and near woodpiles.

Step 3 - Indoor Treatment with Apex Roach Gel Bait

Apex Roach Gel Bait is an effective bait that contains food attractants roaches cannot resist and is combined with a slow-killing active ingredient. Because it works slowly, the roaches will ingest the product, which will then become a part of their system, and will carry it back to the nest where further elimination of the population will occur.

Before applying this product make sure to eliminate food and water sources. Clean your whole home, making sure not to use cleaning chemicals. Use only soapy water. Wipe and clean countertops, vacuum and mop kitchen floors, and take out the garbage. Do your best to clean your home and reduce competing food sources.

To use Apex, simply apply a pea-sized drop of the gel bait every 12 to 18 inches. Place them in cabinets, shelves, drawers, cracks and crevices, and around plumbing entry points. You can even place Apex under appliances by using a business card and applying a drop to the business card and then sliding it underneath appliances.

Remember not to disturb or kill the roaches that come in contact with the product, and remember not to use cleaning chemicals or other insecticides in the places where you applied Apex for at least 5 days. Let 5 days go by and let the roaches feed on the product undisturbed, and do not use cleaning supplies or products for this period of time.

Step 4 - Indoor Application of Ficam Bait

You can apply Ficam Bait indoors as well in your attics, crawl spaces, and basements. Apply at the rate of 4 pounds per 1,000 square feet. Make sure to apply in areas of attics, basements, and crawl spaces where you have noticed feces or Smoky Brown roaches.

  • Remember to keep your home as dry and moisture-free as possible by getting rid of any standing water, cleaning out your rain gutters, fixing leaky faucets, and repairing faulty plumbing.
  • Seal and close off any cracks and crevices found inside and outside your home. Use caulking to eliminate slits, openings, or holes that are being used by roaches to travel into and around your property.
  • Also, get into a regular cleaning schedule after you have applied treatment. Vacuum, sweep, and mop your whole home regularly. Wash your dishes every night and make sure the sink is completely dry. Do not let pet food and water bowls out in the open overnight. In the yard, get rid of yard debris, leaf litter, woodpiles, logs, rocks, and general clutter that can create harborage areas for Smoky Brown cockroaches.
  • Finally, remember to spray Supreme IT every 90 days on the perimeter of your structure to maintain a protective barrier that will repel Smoky Brown roaches.
