What is Boric Acid and How Does It Work?

Boric acid is a white, odorless powder derived from boron, a naturally occurring element. It works as a slow-acting poison for many insects. When bugs ingest boric acid, it disrupts their digestive and nervous systems, leading to death. Additionally, the abrasive texture damages their exoskeletons, accelerating dehydration.

The key to boric acid's success lies in its dual-action mechanism: contact and ingestion. Insects that walk through boric acid carry it back to their nests, where it continues to spread and eliminate the colony over time.

1. Cockroaches

Why Cockroaches Are a Problem

Cockroaches are among the most resilient pests. They can survive for weeks without food, reproduce rapidly, and hide in the smallest of cracks. Worse, they contaminate food, spread bacteria, and worsen asthma and allergies.

How Boric Acid Eliminates Cockroaches

Boric acid is lethal to cockroaches when they ingest it or come into contact with it. It sticks to their legs and antennae, and as they groom themselves, they consume the powder.

Application Tips:

• Mix 50g of boric acid with 100g of powdered sugar and a few drops of water to form a dough.
• Place small balls of the mixture in corners, behind appliances, and under sinks.
• Reapply every two weeks until the infestation subsides.

Recommended for indoor use only.

2. Ants

Why Ants Are a Problem

Ants are persistent invaders, especially in the kitchen. While some species are merely a nuisance, others can damage structures or contaminate food.

How Boric Acid Eliminates Ants

Worker ants carry boric acid-laced bait back to their colony, feeding the queen and larvae. Within days, the colony starts to die off.

Application Tips:

• Dissolve 5g of boric acid and 25g of sugar in 100ml of warm water.
• Soak cotton balls in the solution and place near ant trails.
• Refresh every 3 days for best results.

Avoid placing in direct contact with food or kitchenware.

3. Silverfish

Why Silverfish Are a Problem

Silverfish are destructive pests that thrive in humid environments. They feed on books, wallpaper glue, clothing, and even pantry items.

How Boric Acid Eliminates Silverfish

Silverfish come into contact with boric acid dust in cracks and crevices. The powder damages their exoskeleton and eventually kills them.

Application Tips:

• Dust 10-15g of boric acid powder in areas like baseboards, behind toilets, under bathtubs, and in closets.
• Apply in thin layers using a hand duster or squeeze bottle.

Keep out of reach of children and pets.

4. Fleas

Why Fleas Are a Problem

Fleas can infest carpets, furniture, and pet bedding. They reproduce quickly and can cause allergic reactions in both humans and animals.

How Boric Acid Eliminates Fleas

Boric acid dehydrates fleas at all stages—eggs, larvae, and adults—by absorbing the waxy coating that protects them.

Application Tips:

• Sprinkle 20-30g per square metre on carpets and upholstery.
• Let sit for 24-48 hours, then vacuum thoroughly.
• Repeat every two weeks during active infestations.

Do not apply directly on pets.

5. Termites

Why Termites Are a Problem

Termites are highly destructive pests that can silently eat through wooden structures, causing costly damage before they're even noticed.

How Boric Acid Eliminates Termites

Boric acid acts as a stomach poison when termites ingest treated wood or bait. It also weakens their ability to digest cellulose.

Application Tips:

• Drill small holes into wood and inject a boric acid and glycol mix (e.g., 100g boric acid in 500ml glycol).
• Alternatively, apply boric acid powder directly into termite galleries.
• Monitor activity and re-treat as necessary.

Consult a pest control expert for large infestations.
