How to Find Cockroaches

Locating cockroaches in your home involves knowing where they hide, recognizing the signs of their presence, and identifying common entry points.

Step 1 - Learning Common Cockroach Hiding Spots

Cockroaches tend to seek out areas that offer darkness, moisture, and a nearby food source. Some of their favorite hiding places include:

Kitchen Appliances

Cockroaches, especially the German Cockroach, frequently take shelter behind refrigerators, under stoves, and inside microwaves. These spaces often provide the warmth they crave. Clear food residue from these places, which serves as a tempting buffet for them.


A pantry stocked with food is a complete paradise for roaches. They dig into cardboard boxes and paper bags, feasting on cereals, grains, and other dry goods.

⚠️ Remember to seal food containers tightly and regularly vacuum in and around your pantry, especially when carboard or paper are stored.

Water Pipes and Drains

Both the American and Oriental species of cockroaches gravitate toward moisture-rich environments like bathrooms. You can often find them nesting around leaky pipes under bathroom and kitchen sinks and hovering around drains.


Spaces beneath or inside furniture provide excellent concealment opportunities for cockroaches. Regularly vacuum and clean under couches, wardrobes, and in the bathroom to discourage infestation.


Cockroaches can infiltrate electronics, finding comfort in the warmth generated by devices. Regular, thorough cleaning around plumbing helps deter these insects.

Step 2 - Understanding the Signs of Cockroaches in Your House

Clear indications of a cockroach presence include spotting live or dead roaches, cylindrical, brown feces, and identifying a roach nest.

  • Spotting live or dead roaches
  • Cylindrical, brown feces, equivalent in size to a grain of rice.
  • Discovery of egg capsules
  • Unpleasant and musty odor

Step 3- Knowing Where Cockroaches Come From

Cockroaches are adept at squeezing through tiny cracks and crevices. They can enter your home via gaps in doors or windows, vent openings, and where utility pipes enter the house. Understanding these common roach sources is key to preventing their entry.

Effectively sealing off these potential entry routes significantly helps in your quest for a cockroach-free place.

How to Get Rid of Cockroaches?

Your battle with roaches moves beyond cockroach spots discovery to active control and elimination. Here, we highlight practical steps focused on the do-it-yourself approach and signals that indicate the need to call in a pest control professional.

DIY Solutions

Begin with kitchen cleanliness. Cockroaches, particularly the German cockroach, find comfort in the kitchen, attracted by food residues and water sources. Hence, it’s crucial to maintain cleanliness, wipe surfaces, control moisture, seal food containers, and remove pet food after meal times to deny these bugs any sustenance. Essential housekeeping tasks include regularly vacuuming the floor, cleaning around kitchen appliances and sink drains, and knowing how to handle cockroach infestations effectively:

  1. Regularly vacuum the floor.
  2. Clean around kitchen appliances and sink drains.
  3. Dispose of trash promptly and properly.

Use traps, sprays, and baits. Efficient roach killers like roach motels, sprays, and baits can prove useful, especially on paper-based products. Place traps in common infested areas such as under sinks, behind appliances, and inside cabinets to capture wanderers. For German cockroaches considered as the most troublesome, bait stations or gels are ideal.

Seal hiding spots. Use caulk or a similar substance to seal tiny cracks, crevices, and holes through which roaches can enter your home. Tiny gaps around plumbing wall and floor junctions are worthy of keen attention.

When to Call a Cockroach Pro

Implementing DIY solutions can control minor infestations. But, roaches like the American and Oriental cockroaches that prefer dark, damp spaces, often need professional help, especially when the infestation seems beyond control. Here are some signals it’s time to call a pest control professional:

  1. When you see droppings or feces in random spots
  2. If the foul, musty smell characteristic of cockroaches fills the room
  3. Persistent sightings of live cockroaches in the day, even after implementing DIY solutions, indicate that you might need professional help in dealing with roaches.

Remember, different species of cockroaches require different strategies. Professionals efficiently diagnose the species, assess the infestation level, and customize cockroach control procedures accordingly. So, they increase the chances of keeping your house roach-free in the long run.

Misconceptions About Cockroaches

Transitioning into another imperative section, we confront head-on the common misconceptions about cockroaches.

1. Cockroaches Only Infest Dirty Spaces

First on the list, it's a precedent-setting mistake to assume cockroaches only infest dirty spaces. While these nocturnal creatures indeed thrive in areas with abundant food sources like untidy kitchens, they're just as likely to invade clean homes. Cockroaches get lured by readily available food, pet food, water, and openings that provide shelter.

For instance, they often hide and lay eggs in the smallest cracks around appliances, behind furniture, and in any other rooms in the house. So, maintaining a spotless environment helps but doesn't fully guarantee immunity from a cockroach infestation.

2. All Cockroaches Look Alike

It's important to realize that species of cockroaches vary significantly in appearance. For instance, the German cockroach (light brown and small) differs vastly from the American cockroach (large and dark brown). Judging by the size and color alone can lead to misidentifications, hindering effective elimination strategies.

Contrary to popular belief, cockroaches also differ in their favored living environments and habits. Oriental cockroaches, for instance, prefer cool, damp areas and are mostly found near plumbing or in bathrooms.

3. Pesticides Can Handle All Infestations

Last on the list is the misconception that any roach can be eliminated with generic pesticides or sprays. Species of cockroaches exhibit varying degrees of resistance to specific pesticides. So, using the wrong method might add fuel to the fire, making professional intervention crucial in heavy infestations.

Taking these misconceptions into account can support more effective cockroach control, allowing us to tailor strategies to the specific cockroach species and infestation severity.

Final Thoughts

We've also revealed several cockroach myths, shedding light on the reality of their habits and habitats. Our arsenal of DIY solutions is now packed with effective strategies to combat these bugs.

But remember, it's not a one-size-fits-all approach - the battle plan should be tailored to the specific species and severity of your infestation.

And when the going gets tough, don't hesitate to call in the professionals. They're equipped with the right tools and knowledge to handle severe infestations. So here's to a cockroach-free home, because we've got this!
