The duct tape trap is truly the Old Fashioned of co*ckroach traps, pest control reduced to its simplest ingredients: a sticky surface and something to bait the bugs onto that sticky surface.
For the trap: one upside-down strip of duct tape.

Boric acid tops even baking soda when it comes to killing co*ckroaches. With little more than a sprinkle on the floor, boric acid acts as an all-natural poison to take down dirty roaches in just days. Or, spread a dusting on a paper plate and bait it right in the middle with a piece of orange peel.
We’ve also put together a handy Roach-Free Recipe for killing co*ckroaches with just 2 ingredients: boric acid and a dollop of peanut butter.
4. Irresistible Roach Cookies
Grade: A
Speaking of sweets, we’ve cooked up one of the deadliest home remedies to kill roaches ever, and it’s packed in a delicious (to roaches) dessert. Our simple no-bake roach cookies recipe combines the irresistible draw of raw cookie dough with the roach-killing power of boric acid.
5. DE to Be co*ckroach-Free
Grade: B
It’s a little less common than baking soda but, if you have a pool at home, you probably have a tub or two of diatomaceous earth (DE) sitting next to its filter. Great start! But EPA-registered, food-grade DE is the one you want to buy. DE is an amazing co*ckroach killer. All it takes isa light dusting to damage a roach’s exoskeleton and dehydrate it to death.
Mix equal parts DE and powdered sugar and spread a very light coating on all at-risk surfaces to kill any co*ckroaches craving sweets!
Safety tip: DE may be natural, but even the food-grade variety can hurt your lungs if you breathe it in. Wearing a protective mask when using DE is recommended.
6. Kill Roaches with Borax
Grade: B+
There’s one more super-powered powder that’s easy to find, easy to use and effective as heck: borax. Use this laundry product as one ingredient in a variety of roach-killing recipes, from sugar and borax to cocoa dusts and borax balls. Check ’em all out here!
7. Cornstarch Plus Plaster of Paris
Grade: B
Take two common household products, mix them together and create a great roach killer in no time at all. Equal parts will do for this recipe, which attracts roaches with the promise of a starchy snack and kills them quickly. Apply it in cracks, crevices and places you think roaches are hiding.
8. Petroleum Jelly to Trap Roaches
Grade: C
Have some petroleum jelly in the closet? While it’s not a repellent or toxic to roaches, it’s an essential part of an awesome roach trap.
Choose an empty glass jar, beer bottle or wine bottle. Place a little bait at the bottom. Then, rub petroleum jelly all around the upper half of the inside of the jar or bottle. Tape a bookmark or straw to the outside as a ramp. This way, roaches can easily climb in for the food but can’t climb back out!
9. Down the Drain: Bleach or Ammonia to Kill and Keep Out
Grade: C-
Sometimes, roaches like to hide in drains but you don’t have to trap them at their convenience. For a quick-and-dirty way to kill roaches right where they’re hiding, pour 1/4 cup of bleach into the drain and don’t forget to plug it! In 30 minutes, thoroughly flush it with plenty of water. Always be careful when handling bleach!
A mixture of water and ammonia dumped down the drain also warns roaches to stay away with its powerful smell. And, of course, a thorough cleaning with ammonia signals to roaches that there’s no food to be found.
Home Remedies to Prevent and Repel Roaches
Repellents are like power-ups in a co*ckroach control system: they won’t get rid of roaches on their own but they can help by making your home less attractive to the bugs.
Great roach repellents include:
- Essential oils
- Bay leaves
- Vinegar
- Cleaning and exclusion

10. Repel Roaches with Essential Oils
Grade: A
One of the best natural remedies for roaches, essential oils are effective and smell great, too. That is, unless you’re a co*ckroach.
For example, they simply can’t handle the potent, refreshing scent of peppermint essential oil. Roaches avoid its aroma like it’ll kill them (which—fun fact—it can!). Cypress oil is another strong repellent; dilute it with water and spray it anywhere you’ve seen roaches to send them away.
Lemongrass oil is one of the strongest natural roach repellents available. Catnip oil works, too—just don’t let your cat near the areas you’ve treated!

12. Using Vinegar to Prevent co*ckroaches
Grade: C
Vinegar doesn’t kill co*ckroaches but you can create a few effective home remedies for co*ckroaches with vinegar in a starring role.
Mix vinegar with tea tree essential oil or cedar oil for a powerful cleaning and roach-repellent solution.
There’s one more way to use vinegar to prevent roaches and it’s more effective over time than any other repellent: cleaning.
13. Cleaning: The Best Way to Keep Roaches Out for Good
Grade: A
Nothing beats good ol’ fashioned cleaning for permanent pest control! Roaches look for easily accessed food and water sources, and when they can’t find them, they either die or leave. That makes basic, thorough cleaning an awesome co*ckroach remedy that can make a bigger difference than you think!
The key is thinking like a roach: where can I find a few crumbs and a sip of water each day?
These bugs can get by on water from a leaky faucet, crumbs under furniture or appliances, grease splatter on the stove, old papers boxed up in the basem*nt, and even—disgustingly—the bodies of dead roaches.
While you’re in the six-legged mindset, think about where you’d most want to hide away during the daylight hours: dark, cluttered storage areas full of cardboard boxes and old papers for a snack. Swap the boxes for bins with lids and do some organizing to take away a co*ckroach’s favorite hideouts.

Home Remedies for Specific Species Control
Get Rid of German co*ckroaches
A notorious house pest around the world, the German co*ckroach has a reputation for spreading ruthlessly and causing major problems for homeowners.
In addition to reproducing rapidly, German roaches are stubborn. They tend to display bait aversion more often than other species, making it tricky to eliminate them with steady applications of one type of bait.
14. Rotate the Bait
Grade: A
Plan to rotate the baits you use in traps to prevent resistance; German roaches are particularly good at adapting to and avoiding traps if they get used to smelling one flavor or ingredient.
Stop Wood Roaches from Flying Indoors
Indoor run-ins with wood roaches are likely the result of a few wanderers that got stuck on the wrong side of an open window.
The best way to prevent wood roaches is through exclusion:
15. Screening All Visitors
Grade: A
What about home remedies to get rid of co*ckroaches when the little buggers fly inside?
Try any of the above! But nothing is more effective at keeping bugs outside than window screens and screen doors. If your screens are a few-too-many-seasons old and featuring a few holes, attach some coarse steel wool or, in a pinch, a piece of duct tape. You can buy a magnetic screen “door” for under $10, too.
16. Draw the Blinds on Bugs Attracted to Light
Grade: B
Wood roaches attracted to light have it too easy on spring and summer evenings; the windows are open, the patio lights are on and people are in and out of the house. These bugs can fly straight inside, guided by the light.
The solution is simple: keep the shades and blinds drawn. Hiding the lights lets the bugs stay outside where they belong.

We’ve already covered roach motels and roach-killing dusts. Now, use these great home remedies to get rid of roaches in your car, too!
