Natural Roach Repellant: Vinegar
Because vinegar is such a potent cleaning agent, any house cleaned with a water and vinegar solution will automatically discourage cockroaches from setting up shop inside.
Cockroaches are discouraged by the smell of vinegar, as well as the fact that this solution will disinfect surfaces and dull the scent of food or drink spills.
Baking Soda and Sugar
Baking soda is a popular leavening agent in breads and baked goods, helping to ferment the dough and expand it during the baking process.
When eaten by a cockroach, the same process takes place. However, when it happens inside a cockroach’s body, the effect spells out death to the pest.
Essentially, a cockroach that eats baking soda will expand from the inside-out, eventually bloating so much that it keels over.
To lure a cockroach to eat baking soda in your home, simply mix it with sugar and deposit small piles of the powder around cracks and crevices in your home, or wherever you’ve seen cockroaches in the past.
Citrus Juice Repellent
Lemon and lime juices are another scent which serve as an irritant to the cockroach. Because of their overbearing smells, cockroaches will be deterred in homes that smell strongly of lemon or lime. This is actually one of the reasons that so many household cleaners use a lemon scent!
Here’s how you can make it work for you: if you’re not already using a lemon-scented cleaner, you can make your own repellent by mixing pure lemon juice with water in a spray bottle and spraying clean areas of your home.
Occasionally, people will turn to their cleaning closet for cheap quick solutions to kill roaches. Bleach is a popular solution in most homes and constantly comes up as a question. Can bleach kill roaches? We recommend avoiding it. Checkout out guide here for more information on why.
Our 4 Pronged Approach To Killing Roaches Fast
Cockroaches may be disgusting, but they are thankfully one of the more “beatable” pests you could have (unlike bed bugs).
Here at Pest Strategies, we’ve developed a four pronged approach to defeating cockroaches. Each “prong” if apart of an overall strategy you should deploy.
Using professionally-developed chemical cleaners will always be the best way to get rid of cockroaches.
While there are a few different types of chemicals that work in different ways, we recommend that you maximize the effectiveness by combining all three.
Take a look below to see what the best chemicals are, and how you can use them.
Prong #1: Using Roach Traps
The first prong in our four pronged roach killing strategy includes cockroach traps.
Roach traps provide for a very easy way to monitor and locate the source of your infestation.
The idea is simple…
Buy a number of roach traps and place them in potential areas of roach infesation. These areas include:
- In or around cracks and crevices of your house
- Underneath refrigerators or sinks
- On top or inside of shelves where they would be left undisturbed
- In the corners of your kitchen (area with food) and basement (dark area)
- Any other area where you suspect roaches might be hanging out
Once you’ve deployed your traps, just wait for a bit for some of them to start catching. This will help you decide where to start spraying (prong #2).
Prong #2: Using Roach Sprays
The second prong in our strategy requires the use of roach sprays.
After you’ve deployed your traps, you should have some idea where they are coming from and can strategically spray places in your home to reduce the infestation.
Remember however, a spray acts more like a barrier and an instant contact killer. If used incorrectly, you could end up making your infestation worse by spreading out the colony into new parts of your home (this is bad).
The best use of sprays is clear out the insides of walls (wall voids) and the hard to reach crevices.
Ideally, you would have already deployed cockroach baits (prong #3) to help drive the remaining roaches to spread the poison throughout their nests.
Sprays work because cockroaches have millions of small holes throughout their bodies, which can immediately become susceptible to an insecticide that’s been sprayed in an certain area.
Roach spray works to quickly irritate and short-circuit a cockroach’s central nervous system, leading to death. The active ingredient for most sprays is pyrethoid, which stems from chrysanthemum flowers in the wild.
When you’ve deployed roach traps and have begun to spray in hard to reach crevices of your home, you can move onto prong #3 and prong #4 of our 4-part strategy.
Prong #3: Using Roach Baits
Roach baits are the 3rd prong in our strategy because by now you should have a good sense of where your infestation is hanging out (via the traps).
The baits should be placed in such a way where the roaches can get to them and bring the bait back to the nest with the remaining roaches.
This method of killing a cockroach is often a slower process than using a roach spray, as the insecticides contained in the bait are in smaller portions, as not to overpower the attractant.
The upside of using a bait is that it’s pre-mixed and ready to be set around commonly-infested areas of your home. Simply leave a few baits sitting in dark spots where you found the traps to be working, and you should be sweeping up dead cockroaches within a few days.
After you’ve seen some success with the baiting, you should also be deploying IGR or Insect Growth Regulator according to the 4th and last prong on our list.
Prong#4: Using Insect Growth Regulators
The one downside of both cockroach sprays and cockroach baits is that they’re usually only effective on mature cockroaches.
This is where an Insect Growth Regulator (IGR) steps in.
Cockroaches lay eggs in white clusters which can be nearly indestructible, glued to a surface and glazed with a protective casing.
An insect growth regulator works as roach baby birth control an makes it difficult if not impossible for roaches to reproduce stopping the lifecycle and your infestation.
