- Set up Roach Traps
Another way to get rid of roaches is by using traps. There are different kinds of cockroach traps. Some traps simply capture the roaches while others will also kill the nasty insects. Here are some of the common roach traps:
- Store Bought Adhesive Traps
Store bought adhesive roach traps come in different designs. However, they all use the same principle of ensuring roaches get stuck on the adhesive material once they enter the trap. For this pest control method to be effective, use some bait to lure the roaches to the trap.
- Funnel Trap
This homemade trap is a simple way to capture roaches and kill them. You will need a plastic water bottle, a pair of scissors or sharp knife, adhesive tape, and some bait to set up the funnel trap.
Set up Process:
- Cut off about one quarter of the plastic bottle from the upper part. The cut piece will act as a funnel when inverted inside the bottle.
- Now, fill the cut bottle with soapy water and invert the funnel in it. If the funnel does not fit, apply masking tape around the rim to hold it in place. Position the funnel trap close to walls or places where cockroaches like to visit.
- Lace the funnel with ground coffee or any other type of bait. The funnel entrance will cause the cockroaches to fall directly into the trap but will make it harder for them to escape. Eventually, the roaches will suffocate due to the soapy water and drown.
- Petroleum Jelly Trap
This DIY cockroach trap works pretty much like the store bought adhesive trap. However, the petroleum jelly will make it difficult for cockroaches to crawl away from the trap once they are captured.
To prepare this trap, you will require a wide mouthed jar, some bait and petroleum jelly.
Set Up Method:
- Place fruit peels inside a wide mouthed jar.
- Rub some petroleum jelly around the inner edge of the jar.
- Leave the jar overnight within easy access to cockroaches. Roaches will be attracted to the fruit peels but will find it difficult to leave due to the slippery petroleum jelly on the edge of the jar.
- Kill any captured roaches manually, and throw them in the dustbin.
- Cucumber Trap
The cucumber trap may sound too good to be true, but many people have found it to be effective. For some reason, cucumber peels react with aluminum and produce a pungent smell that’s lethal to roaches.
To set up this trap:
- Save cucumber peels from previous meals and then place them inside an aluminum can.
- Leave the can with the peels overnight in an infested room that has high cockroach traffic.
- From there, it’s a waiting game. The cockroaches will be attracted to the cucumber peels and die slowly when exposed to the pungent smell.
- Use Natural Cockroach Repellents
Another way to reduce cockroach populations in your house is by repelling them. There are many natural products you can use for this purpose, but some of the most effective have been listed below.
- Bay Leaf
Roaches cannot stand the smell of bay leaves. Therefore, you can use this plant as a natural repellent for roaches. The best places to find bay leaves are stores that sell Indian or other Asian spices.
To drive away roaches with bay leaves, follow this procedure:
- Dry a handful of fresh bay leaves in the sun. To skip this process, opt for dried bay leaves instead.
- When ready for processing, crush the leaves into a fine powder using a pestle and mortar.
- Sprinkle the powder near cockroach nesting places. The powder’s strong smell will irritate the cockroaches, causing them to migrate somewhere else.
- Continue applying the bay leaf powder all over your house for several weeks until there is no sign of roaches.
- Cayenne Pepper
Cayenne pepper can be used to fend off roaches as well. Opinion remains divided on why it works on roaches. Some people say it’s the smell while others think a specific ingredient in the pepper repels cockroaches.
What’s important, though, is that roaches will not stay in a home where they come across pepper when crawling about in search of food and water.
Using Cayenne Pepper to Repel Roaches:
The simplest way to use cayenne pepper to repel cockroaches is sprinkling it behind any object or place where you suspect roaches are hiding. Alternatively, follow these steps to make a more potent concoction:
- Mix 1 tablespoon of cayenne pepper with one clove of garlic and white onion.
- Crush the mixture with a pestle and mortar to make a paste.
- Combine the paste with 4 cups (1 quart) of boiled water and let it cool.
- Pour the mixture in a spray bottle and apply it on roach infested areas around your home.
- Essential Oils
Cockroaches do not like the smell of certain essential oils. A few examples include cedar, lemon, and fir oils. The fact that these oils leave a pleasant smell in your home is an extra bonus that makes them worth using.
You can mix these oils with Diatomaceous Earth (DE) and apply the mixture close to cockroach nesting places. The roaches will die after scampering over the treated areas as they try to flee. This is because DE destroys their exoskeletons.
How to Use Essential Oils to Repel and Kill Roaches:
- Mix 2 cups of Diatomaceous Earth with 10 to 12 drops of cedar essential oil plus 4 drops each of lemon and white fir essential oils in a bowl.
- Sprinkle the mixture in places where roaches frequent or hide such as areas close to trashcans, basements, and so forth.
- Leave the mixture in place overnight and vacuum the next morning. With this remedy, you’ll also repel mites, bedbugs, ticks, spiders, fleas, and other insects that hate the smell of essential oils.
- Ammonia and Water Solution
Ammonia gives off a pungent smell that even irritates humans. So, imagine what it can do to roaches. All you have to do is dilute some of it with water to make the smell a little less unbearable before applying the diluted ammonia on places where roaches are likely to be hiding.
Using Ammonia and Water to Ward off Roaches:
- Dilute 2 cups of ammonia with 1 bucket of water.
- Use this solution to wash surfaces in your kitchen, bathroom and other cockroach infested rooms.
- The roaches will escape from your house because of the irritating scent of ammonia. For the best results, continue applying this treatment once every fortnight to keep the roaches away from your home.
Catnip is not toxic to pets and kids. Therefore, it offers a safe way to get rid of roaches. Its active ingredient, nepetalactone, not only repels roaches, but also mosquitoes.
Keep in mind that catnip tends to make cats hyperactive and difficult to control. Therefore, it might not be a good roach repellent if you have a cat in your house.
Methods of Using Catnip to Drive Away Roaches:
- Get small sachets of catnip from your local herbal store. You can also buy catnip seeds and grow the plant in your garden for future use. Place the catnip sachets in places where you have spotted roaches before.
- Alternatively, make catnip tea by mixing one teaspoon of the herb with two cups of water. Sprinkle the mixture on infested areas using a spray bottle.
Apart from catnip, ammonia, essential oils, cayenne pepper, and bay leaf, Listerine also works as a natural repellent for roaches.
- Simply mix this mouthwash with equal parts of water.
- Use a spray can to apply this mixture on places where roaches frequent.
- Alternatively, add a few drops of dishwashing detergent to the Listerine mixture. Spray the solution directly on any visible cockroaches to kill and ward them off.
- Pinesol and Bleach
When you want to draw out roaches and kill them directly, a mixture of pinesol and bleach will do the trick. These compounds give off a potent smell that causes roaches to come out of hiding. In fact, you will even need to keep the windows open because of the extremely strong smell.
Process to Follow:
- First, inspect your home for cockroach nesting places.
- Mix bleach and pinesol in equal parts and add some boiling water.
- Pour the mixture close to roach nests. When the roaches come out of hiding, spray them with homemade insecticide or any other effective treatment that kills them instantly.
How to Get Rid of Roaches Using Medical Options
If you find that the home remedies described above are not effective at solving a roach problem, the next best option is to try medical pest control methods. When we say “medical” treatments, it means using chemicals to control and reduce cockroach populations. Here are some of the effective methods you may want to try.
- Spray Roaches with Professional Grade Pesticide and Insecticide
Professional grade pesticides are far more effective than any homemade cockroach insecticide. Pesticides that contain the ingredient Cypermethrin are quite effective at killing roaches.
If you opt for store bought insecticides, ensure to look for a reputable brand. The chosen insecticide should also be clearly labeled for use on roaches if you want it to be effective.
You should only use this method as a last resort because professional grade pesticides and insecticides are very toxic to pets.
- Use Pharmaceutical-Made Roach Bait
Store bought roach baits usually come in the form of gels. The good thing about them is that they act as a slow poison. So, any roach that feeds on the bait takes back the poison to the nest, which eventually kills the entire colony.
Remember that proper bait placement is important when using this roach killing method. Therefore, place the bait in places where cockroaches are likely to visit or hide such as underneath sinks, furniture, and crevice openings for shelves.
How Long Does it Take to Get Rid of Cockroaches?
Getting rid of roaches can indeed be a big challenge because these creepy pests know how to hide in the most hard to reach places. How long it takes to get rid of them from your home depends largely on the size of infestation and the species.
The tiny German roaches are typically harder to exterminate because they hide so well and reproduce very quickly.
Regardless of the species, the truth is that solving any kind of roach problem will take up to several weeks. In fact, roaches are almost never eliminated with just one treatment.
For heavy infestations, you might need up to eight weeks or more. However, a satisfactory result can be achieved in a couple of weeks when dealing with a light infestation.
Tips to Prevent a Cockroach Re-infestation
- Spray Liquid Concentrate, or apply any natural cockroach repellent around the home once or twice a week. If you choose to spray store bought insecticides, be sure to use different brands as roaches tend to develop a tolerance to pesticides overtime.
- Minimize hiding places for roaches by sealing cracks on walls, pipe openings, window moldings, doors, and floors.
- Check for cockroach nests and destroy their eggs before they hatch.
- Clean your yard and gutters to prevent roaches from breeding outside the house. Store woodpiles far from the house and always treat barns and storage areas with a natural insecticide to ward off roaches.
- Never leave dirty dishes in the skin overnight and keep workstations free from food scraps.
- Repair leaking taps.
- Hire a professional exterminator to perform regular pest inspections.
