You would probably never think to use this to get rid of bugs but finally there is a cheap, easy and safe way to kill unwanted pests.
Borax is a white mineral in some alkaline salt deposits, used in making glass and ceramics. You probably know of it as being a household cleaner, among other things.
Borax is very effective in killing and controlling various types of insects, including fleas, silverfish and beetles. It is always considered one of the most effective methods of controlling cockroaches. It has the added benefit that its residual action is more effective against newly hatched insects than most chemical sprays.
It works perfectly if it is applied by lightly layering the powder in areas that insects are a problem. If you don't know where they are coming from, put it on the edges of all your cabinets, baseboards, under the sink and in bottom cabinets, tipping the spoon and tapping gently to sprinkle the powder. You can make it more appealing to bugs by mixing borax with honey or corn syrup to form a paste and leaving it where insects can find it.
The important thing to remember is to place the borax on a clean, dry surface and if the powder gets damp or wet, clean it up with a wet cloth, dry the area and re-apply.
Borax works so quickly that you will see results within days or a week.
It works because when the insect walks through the dust, it clings to their legs and is eventually ingested, poisoning the insect.
To get rid of fleas, you can sprinkle it on your carpet, hardwood or any floor surface. Leave it for a couple days then vacuum it up. It is safe to walk in, just try to ensure kids aren't touching it or dogs aren't licking it. It is poisonous, but even though a small amount ingested won't hurt you but, it still is not healthy to ingest. If possible, while it is on the floor block animals and children from that room while it's there.
Many existing bug repellent products have Borax as their main ingredient, so by just buying Borax you are savings a lot of money. You can usually find it in the laundry/cleaning aisle of any grocery store or on Amazon.
