3 Ways To Kill Cockroaches Without Hiring An Exterminator

Let’s be honest here: hiring a pest control professional is never cheap.  They do provide real value – especially for properties suffering a major infestation – but sometimes money is tight and you need a more affordable solution.

If that’s the case for you, there are cheaper ways to get rid or roaches… simple methods which you can do by yourself… and that don’t require a call to the pest control guys.   Here are a few of them:

Boric Acid

Boric acid was first registered as an insecticide in 1948.  It is a bluish-white powder, and it kills any cockroach that comes into contact with it.

To make use of it, just mix boric acid with equal parts flour and sugar. Then sprinkle the mixture around the perimeter of your property’s rooms.

The sugar in the mixture will attract the roaches.  When they come into contact with it, the boric acid seeps into their exoskeleton, causing fatal dehydration.

Is boric acid safe to use around pets and children?

Only when used intelligently.  Boric acid is hazardous when ingested in large quantities, and the sugar-sweetness of your mixture here might convince the kids or cats to go to town.

With that in mind, it’s best to use the mixture in areas inaccessible by your little ones.  Places like behind the stove, behind baseboards and in cracks. And if your loved one shows any signs of boric acid poisoning (muscle weakness, depression, weight loss, diarrhea, vomiting, seizures, etc.) then immediately consult a physician.

You can buy boric acid for about $10 from

Vegas Roach Trap

This is an effective DIY roach trap, which I showcased in a previous post. The trap works by attracting roaches with a sweet liquid (stale beer, water with coffee grounds, sugar water) and then drown them in that same liquid.

The trap has both pros and cons. Keep an eye out for a future article, where I’ll discuss the Vegas Roach Trap in more detail.

Garlic Repellent

This garlic repellent is a simple, easy and non-toxic spray. You can make it yourself by combining a few items from the grocery store.  Here’s what you do:

  1. Crush one (1) garlic clove.  Set your crushed garlic aside.
  2. Chop one (1) whole white onion. Mix the onion and crushed garlic together.
  3. Add six teaspoons of cayenne pepper to the mixture.
  4. Place all ingredients into one quart of water.  Let it sit for one hour.
  5. Add 3 teaspoons of liquid dish detergent and shake vigorously.

Now, this is important – this garlic based repellent is NOT an insecticide.  It is ONLY a repellent. While it will push roaches away, it will not kill them. This may be a good option if you’re dealing with an incurable infestation (like an apartment in a large complex) or if you’re philosophically opposed to killing insects.
