Cockroach Killer - How to Get Rid of Cockroaches Fast & Efficiently

Cockroaches are hard to kill, they are fast, tiny, sneaky and are considered to be some of the most resilient animal species on Earth. Roaches usually run away when the lights are turned on and hide in narrow places, which makes their extermination very hard. A proper cockroach killer is required for each particular infestation. It can be bought at a store or done as a homemade remedy for cockroaches.

There are 4 common cockroaches species in UK and each of them is pretty hard to exterminate:

  • American cockroach
  • German cockroach
  • Brown banded cockroach
  • Oriental cockroach

The Oriental cockroach likes warm surroundings and usually hides near electrical appliances such as heaters, ovens, drains and waste pipes.

Cockroach Killer – Home Remedies Anyone Can Make

Before you read and try any of the solutions suggested below, think about the difference between a cockroach repellent and a cockroach killer. The repellent doesn’t kill roaches it just keeps them away from the area it’s used on.

The mixtures below are cockroach killers and after application, there will be dead roaches for sure, which means cleaning and disinfection after the extermination should be done. Make sure you can clean up afterwards.

Diatomaceous earth

The diatomaceous earth is the most popular alternative to a pesticide you can use for cockroach extermination. The structure of this siliceous sedimentary rock damages the exoskeleton of the roaches and causes dehydration. This is one of the reasons why after roaches make contact with the diatomaceous earth, their activity increases, they simply look for more water.

The most comprehensive way to make a cockroach killer with diatomaceous earth is to combine it with something that roaches lick such as cocoa powder or flour. Simply mix both and sprinkle anywhere you’ve spotted the crawling insects. Diatomaceous earth is not toxic and is not harmful to pets and humans. It’s even suggested as healthy and edible to people who have problems with their hair, nails and skin.

Boric Acid and Cornstarch or Sugar

Another very effective cockroach killer that can easily be made at home is a mix of sugar (or cornstarch) and boric acid. The sugar or the cornstarch act as a bait for the roaches while the boric acid poisons them by drying their exoskeletons similar to the way diatomaceous earth does.

Sprinkle the mixture where the cockroaches appear and they will get on it usually during the night when lights are off and the bug get out of their hidings.

Soap Solution

This is probably the most budget cockroach killer and is also very effective. Make a soap solution with water by adding a bit more soap and fill an old spray bottle with it. Spray it directly on the cockroaches otherwise, it will have almost no effect at all.

Once covered in the soap solutions, the pores of the roaches will be clogged which will prevent them from absorbing oxygen. The results is quick eradication. The only difficulty with this cockroach killer is the fact you have to wait for the bugs to get out and spray them directly.

Professional Cockroach Killer Spray

Killer sprays for cockroaches are available for a purchase in specialized online stores. They are also provided by pest control companies and are widely available anywhere across UK.

If you don’t want to spend cash on it, consider making one at home. The places where spraying is recommended are doors, windows, ventilation, openings in pipes, behind kitchen appliances, under beds, in cluttered areas, inside and around sinks as well.

Repellents Don’t Kill Cockroaches

As we already mentioned above, the repellents are not able to exterminate cockroaches but are still a good solution when you only need to ward off the bugs from something in particular. You can prevent a cockroach infestation in your bathroom, your bedroom, or kitchen. Some of the most effective natural cockroach repellents available in any local store are:

Tea tree oil
Bay leaves

Use any of these to get rid of cockroaches anywhere you don’t want to the spot insects anymore. Insecticides are best applied nearby places where food is stored (do not apply the insecticide on food). If you find it difficult to deal with the infestation on your own, don’t hesitate to call a professional. Make sure you also spray the cockroach eggs, they need to be treated to prevent hatching.

Best Roach Killer for Apartments

Not any cockroach is handy for usage in apartments. When the premises are smaller and there different types of hiding for the bugs, some pest control methods are more effective than others.

Dealing with cockroach infestations in apartments is very difficult and 2 methods of extermination have proved as most effective. The good thing is both of them are easy to do by a non-expert and the cockroach killers may be bought instantly without the need of permissions or license.

Cockroach Bait Stations

Baits stations are sold in any larger supermarket and are a very good cockroach control solution for domestic purposes. Their great effect comes from the fact that when a cockroach eats from the bait inside it will die later when it gets to the other cockroaches. They will then consumed the poisoned roach or its faeces and will die as well. By poisoning a few of the bugs, the whole colony gets exterminated with ease.

Bait stations are optimal when placed in the corners of the rooms or behind appliances where drops of food may be left accidentally. Narrow places are also preferred as only the roaches reach and use them for cover. When getting in and out they will spot the bait and will take a bite, which is exactly the first and most important step of dealing with the infestation.

Cockroach Gel Bait
The cockroach gel is an alternative to the cockroach bait traps and is just as effective cockroach killer as the baits. There is even an advantage when using the gel – it’s easier for an application. Usually, the gel is injected into small cracks at the door casing where bait traps cannot be placed.

3 to 5 spots of the gel are most efficient on 10 linear feet for heavier infestations in your home, while 1 – 3 gel spots are enough for small and moderate cockroach infestations.

How to Get Rid of Cockroaches Permanently

Remove Clutter
Cockroaches tend to hide in cluttered areas – they provide shelter and block the sunlight. Household items such as appliances, paper, clothes and furniture are usually the cluttered areas which the cockroaches use for cover.

Declutter those and you will most probably spot the crawling bugs coming out of their cover, don’t be scared, they’ll quickly find a crack or any other place to hide. Though, decluttering can help after that when you start the extermination with the cockroach killer.

Leave No Moisture
When cockroaches get dehydrated, they start searching for water and become extra active. Having areas with high levels of moisture makes the premises prone to cockroach infestations. Therefore, it’s recommended to keep your kitchen and bathroom very dry. If there are leaky pipes or worn grouts, inform your landlord about them and demand a repair.

If there are water pots for your pet, consider drying them during the night, especially if cockroaches have been spotted any time soon.

Don’t leave unpacked food
Food is very attractive to cockroaches. It lures them very fast and is one of the most common reasons for roach infestations. Certain foods attract roaches more and may be found in any household that is not regularly cleaned and maintained:

  • Sugars
  • Meat
  • Peanut butter
  • Milk products
  • Decaying leftovers

Fill Small Cracks
