In this post, we’ll give you proven ways to get rid of Blattidae. You don’t have to worry about choosing different elimination measures for different types of roaches from now on.

What you’re about to read murders all kinds of roaches – once and for all. So, let’s get into the process of Blattidae (or roach) extermination process, step-by-step.

Step # 1 – Throw Away Garbage From All Your Trash Cans To Deny Food To The Roaches

Roaches feed on trash, food wastes, and even on used toilet papers in your bathroom. Throw away the garbage from all the trash cans, both from inside and outside of your home.

If you’ve got a yard or garden, then there’s a good possibility that roaches may enter your home from there.

You may want to eliminate roaches from your yard first before you focus on getting rid of roaches inside your home.

Roaches living outside of your home can sneak in inside while you’re getting rid of them from your yard.

You can check our post on how to exterminate roaches from your yard.

But if you’re living in an apartment, you don’t need to worry about it.

After you’ve discarded the waste from your trash cans and garbage bins, clean them with a disinfectant or phenol.

Step # 2 – Clean Your Home To Discourage Blattidae From Entering Your Home

Roaches love the rot, dirt, and filth. You already have a lot of creeping and crawling in your home.

And you don’t want to make your home a Disney land for them by inviting more roaches from outside.

The second step for getting rid of roaches or Blattidae is to clean your home.

Deep clean your kitchen, bathroom, basement, attic, or any place that provides a favorable condition for the roaches to live and breed.

What are the favorable conditions for roaches? Food waste, moisture, and darkness.

You cut these off and you’ve won 80% of the battle against them.

So, don’t skip cleaning your kitchen cabinets, your kitchen sinks, the medicine cabinet in your bathroom, and inside the bathroom vanity.

These places are perfect for roaches to hide and thrive because they get ample food and moisture.

Check if there’s any water leak from the pipes of your kitchen sink, faucet, and bathroom sinks. If there is, then tighten them up or take help from a plumber.

While cleaning, use a good disinfectant (like these) and Lysol.

Step # 3 – Seal of Cracks on the Walls to Prevent Blattidae From Hiding in Them

The Blattidae or roaches hide inside the cracks of your walls, floor, furniture, and even underneath the drain-net in your bathroom.

So, seal the cracks with cement or with a caulking gun to prevent roaches from hiding there.

If there are any roaches inside, then you’d be mummifying them by sealing those cracks.

Using a caulking gun with a sealant is a preferred way of sealing cracks for roaches and termites.

Because some crevices are too thin to cover by cement. Using a caulking gun is most effective.

You can find thin cracks on your window and panels, on the edges inside your kitchen cabinet, underneath your kitchen and bathroom sinks.

Step # 4 – Use Blattidae Baits To Murder The Roaches

By now, the roaches are in a panic because you’ve cleaned your home, there’s nothing for them to eat, and you sealed off their hiding places.

Now it’s time to nuke them.

How would you do that? There are two ways to do it.

The first way is to squash them under your shoes the moment you see them. Well, this is effective, but it can look ugly.

Plus, the greasy stuff that comes out from the roaches when you squish them can attract other insects like fire ants.

The second way is to use roach baits. Roach baits like these are an effective way to eliminate Blattidae.

But it would be best if you are very strategic about where to keep these baits for maximum effect.

Roaches are social, and they believe in touching each other to communicate.

Plus, they eat each other’s feces. So, one roach, poisoned by a bait, can easily poison the entire roach colony by its touch and poop.

So, here are the places where you can keep the baits –

  • Inside the kitchen cabinets and on the top of the kitchen cabinet too.
  • Behind wall décor or photo frames.
  • Near your kitchen stove. Roaches love to feed on the oil and cooking waste near your stove, so keep one bait there.
  • Inside the cabinets of your bathroom.
  • Near window frames.
  • Inside your trash bins in the yard, bathroom, and kitchen.
  • Inside bathroom vanity and behind the vanity mirror.
  • Also put one in your bookshelf.
  • Underneath your furniture like side tables, sofa, wardrobe, closet, shoe racks, and kitchen island.
  • Inside the furniture of your basement if you have one.
  • In your attic. Keep at least 4-5 baits inside your attic, especially at the corners. Because attic is a place that roaches love and hide.
  • Underneath big appliances like refrigerators, washing machine, coffee maker, and dishwasher.

You can change these baits every other week. Use this measure for at least a month till all the Blattidae are gone.

But what if you still see some roaches roaming around inside your home? Then you need to follow Step # 5

Step # 5 – Use Cockroach Insecticide To Get Rid Of Hard To Kill Roaches

Spray Cockroach Insecticide

If you still see roaches roaming around inside your home, then chances are they are German roaches.

German roaches are the hardest to get rid of. They’re like a roach spartan, and you would need something more effective than a roach bait.

The best way for these tough nuts is to use cockroach insecticide like these to kill the Blattidae.

You don’t need a pest control specialist to spray the insecticide if a few Blattidae show up. But you might need one if the bait strategy is a failure.

Buy an insecticide for cockroaches and go through the directions on the product label to make a spray mixture.

It would be best if you also buy an insecticide sprayer, a cheap one like this is fine.

Spray the insecticide in the following areas –

  • Inside your attic and basement.
  • At the exterior of your home, especially where the wall is in contact with the ground.
  • The doors and window frames.
  • In the cracks on your walls if you spot any.
  • On the drain-net in your bathroom, laundry room, and kitchen.
  • Inside your kitchen cabinet. (DON’T forget to empty your kitchen cabinet before your spray the insecticide)
  • Underneath your bathroom sink, kitchen sink, and toilet sink, especially around the plumbing places.

If you’re using an insecticide, then don’t forget to take appropriate safety measures.

Wear a mask to cover your mouth and nose. Also, wear a pair of gloves to protect your hands.

If you use an insecticide in your kitchen, don’t use the kitchen to cook on that day. Shut the door of your kitchen at least for 5-6 hours before you reuse the kitchen.

Make sure that you DON’T use the insecticide in your kitchen anywhere else than we mentioned. Never spray it on your refrigerator, utensils, gas stove, or any other appliances.

Step # 6 – Use Insect Growth Regulators To Destroy Blattidae or Roach Eggs and Nests

You still have one last thing to do. And that is to remove the progeny of these Blattidae.

By now, if you don’t see any roaches roaming around your home, it doesn’t mean that your home is roach free.

Maybe these roaches have spawned, and the eggs are waiting to hatch.

Now it’s time to destroy their eggs and nests.

The best way to do it is to use insect growth regulators like these to destroy the Blattidae’s larvae and eggs.

So, after you’ve followed all the five steps, it’s time to land one final blow.

Mix the insect growth regulator (IGR) with water and spray the mixture to all the places where you’ve spread the insecticide or used the bait.

Spray the IGR after 2-3 days of insecticide spray for better results.
