If you have ever had a problem with roaches in your home, you know how difficult it can be to get rid of them. Many people turn to pesticides to solve the problem, but these can be toxic to humans and pets. One alternative that has gained popularity in recent years is boric acid. But does it really work?

What is Boric Acid?

Boric acid is a white, crystalline powder that is commonly used as a pesticide. It is derived from boron, which is a naturally occurring element. Boric acid works by dehydrating insects, causing them to die of dehydration. It is also toxic to insects when ingested.

How to Use Boric Acid for Roaches

To use boric acid for roaches, you will need to mix it with a bait. Mix 1 part boric acid with 2 parts sugar and 1 part flour. This will create a sweet, doughy substance that roaches will be attracted to. Place small amounts of the bait in areas where roaches are likely to be, such as under sinks, behind appliances, and in cabinets.

Is Boric Acid Safe?

While boric acid is generally considered safe for humans and pets, it can be toxic if ingested in large amounts. It is important to keep the bait out of reach of children and pets. If you have a severe infestation, it is best to consult a professional pest control company.

How Long Does it Take to Work?

Boric acid can take several weeks to work, as it is a slow-acting poison. You may initially see an increase in roach activity as the bait attracts more roaches, but over time, the population should decrease.

Other Tips for Getting Rid of Roaches

In addition to using boric acid, there are other steps you can take to get rid of roaches. These include: – Keeping your home clean and free of clutter – Sealing up any cracks or gaps in walls, floors, and cabinets – Fixing any leaks or moisture issues – Storing food in airtight containers – Vacuuming regularly


Boric acid can be an effective way to get rid of roaches, but it is important to use it safely and correctly. If you are dealing with a severe infestation or have concerns about using pesticides in your home, consult a professional pest control company. With a little effort and patience, you can get rid of roaches and keep them from coming back.
