2. form them into balls.

3. Place them on a sheet of parchment paper to dry for several hours.

4. Once they’re dry you can add them to the bottom of the dishwasher.

5. Run a short hot-water cycle.

Method2. Boric Acid

Boric acid is derived from borax and is usually combined with an anti-caking agent.

Cockroaches ingest boric acid when they preen themselves after they have walked through the powder.

Cockroaches die because boric acid is a slow-acting stomach poison. Because boric acid also absorbs the cockroach cuticle wax, they may also die from dehydration.

Although boric acid is relatively safe for humans and other mammals, it can be harmful if accidentally ingested and must be kept away from food, children, and pets.

Apply it as a bag of very fine dust everywhere you see roach activity.

Care must be taken not to breathe in the dust when you apply it.

Method3. Lemons

1. Cut a lemon in half and squeeze it directly over your surfaces in your dishwasher.

2. You can also mix some lemon juice with a little water in a spray bottle in order to target those hard-to-reach areas that cockroaches love so much.

The lemon juice will effectively repel these pests, and your fridge will smell amazing too!

An added bonus is that it’s also a natural disinfectant. That’s crucial since roaches carry a host of dangerous bacteria and viruses.

Method4. Bay leaves

Cockroaches are repulsed by the smell!

You probably already have bay leaves on hand, but if not, they’re easily found in any grocery store.

1. Try tucking them or leaving a clump inside the refrigerator or outside where cockroaches are located in your dishwasher.

This method may take a lot of bay leaves and patience, but it’s a nice natural way to send roaches packing.

Method5. Neem Oil

This one keeps away a lot of insects and pests because it contains a certain chemical that’s poisonous to them. It’s found in many sprays and lotions, but pure neem oil will really do the trick.

you might have to spend a little extra cash, but it’s still cheaper than the exterminator.

You can mix it with water in a spray solution and spray your dishwasher with it.

Method 6. Garlic or Cayenne Powder.

there are plenty of spices with strong odors that repel roaches. You can use garlic- or onion powder, and sprinkle it in and around their favorite hangout spots in your dishwasher.

You might even mix the two together for a super pungent repellant!

Method7. Vinegar with Peppermint Oil 

Lots of insects can’t stand these two smells, roaches included.

1. Fill a medium-sized spray bottle with mostly vinegar, and add enough drops of peppermint essential oil so that you can smell it.

2. Give it a shake and get to spraying.

Target your dishwasher, door, racks, filters, arm… all areas in your fridge and roaches won’t come anywhere near your house.

Method8. Baking Soda and Sugar Trap 

Trap Take the smallest dish you can find it can even be filtered or the bottom of the dishwasher.

1. Put a mix of baking soda and sugar in it in a 1:1 ratio. 

2. Set another equally small container full of water near it. 

3. Put them in the top or under your dishwasher.

The sweet sugary smell attracts roaches, so they eat the powder mixture. Once they take a drink of water,

it reacts with the baking soda, and, well, let’s just say the roaches get a bad case of bubble guts that they don’t walk away from.

Keep checking your trap, clean up around it, and replenish it when necessary.

Method9. Catnip

Your kitty might love it, but the same can’t be said about cockroaches.

1. Put some fresh catnip leaves in a sachet you know, those little sheer drawstring bags usually used for steeping tea or another porous bag.

2. Set them inside and outside your dishwasher.

Just remember to change out the leaves when needed so that your anti-roach balls keep their potency!

If you grow catnip in your garden, that’s even better since you’ll always have an endless supply on hand.

besides all those DIY natural treatments, there are also cockroach traps that you can make yourself with ingredients you likely have in your kitchen Once you’ve put them together, place them in the spots where you think the roaches are coming from.

Method10. Soap Solution

Find a soap that contains borax so that your solution packs an even better punch.

Borax is a natural antiseptic and cleaner that’s used in powdered laundry detergents and disinfecting hand soaps.

1. Mix the soap with a little hot water and spread it thickly on your refrigerator.

Cockroaches and similar pests breathe through the pores of their shells and skin, so when they start crawling around in this soap, the borax will get the job done.

Method11. Duct Tape Trap

1. Cut a sizable strip of duct tape off the roll, maybe about the length of your forearm.

2. Put the strip sticky-side-up, and fold down each end so that it’s easy to pick up and dispose of later on.

You’ll also need a bait, Remember, besides sweet sugary stuff, roaches also love fatty foods, so a small chunk of cheese or a dollop of peanut butter with some sugar on top will be perfect.

3. Place your bait in the middle of the strip. 

4. Put the strip close to your fridge

The idea is that the roaches will go after the bait and get stuck in the duct tape on the way.

Note: don’t use a sweet liquid as your bait; this will dissolve the tape’s stickiness!

Method12. The Coffee Trap

1. Grab a clean dry glass jar. 

2. Take a small Styrofoam or plastic cup and fill it with wet coffee grounds.

The cup should be small enough to easily fit in the jar, yet sturdy enough to be unaffected by water. 

3. Place your small cup of wet coffee grounds down inside the jar.

4. Fill the rest of the jar with water, stopping a little below the surface of the bait cup.

5. Put it close to the dishwasher or in the top or under your dishwasher rack.

Roaches are drawn to the smell of coffee too, so they’ll climb in after the grounds but won’t be able to get out since they’re not the greatest of swimmers. 

5. Repeat as necessary, and your population of roaches should eventually be gone.

Method13. Slippery Jar Trap 

1. Grab an empty pickle jar or one of a similar size, and make sure it is completely clean and dry. 

2. Put some bait in the bottom, like that hunk of cheese, sugary peanut butter, or even some pan grease. 

3. spread some petroleum jelly all over the inside of the jar, especially around the inside of the mouth.

4. Put it close to the dishwasher or in the top or under your dishwasher rack.

The cockroaches will climb in to go after the bait, but they won’t be able to climb back up the slippery surface to escape!

This guide will help you to get rid of roaches in dishwasher please use one of the methods, but you may know them all.

You should recognize when this infestation is beyond your control.

Cockroaches might seem like introverts, hiding in isolated spots and whatnot. But they’re actually quite social, just not with you! So if you see 1 or 2, you probably have LOTS more where they came from.

They’ve probably got whole colonies in the walls, roof tiles, sewage system, under the bathtub, and anywhere else dark and out-of-reach.

Roaches are also nocturnal, so they do most of their scavenging while you’re asleep.
