Preventing termites is many times cheaper than treating them and repairing the damage. It rests on three things: deprive them of moisture, separate wood from the soil, and inspect the building regularly.
These steps complement getting rid of termites and address the causes covered in why termites appear.
The idea: Preventing termites is far cheaper than treating them, because they work in secret for years before the damage appears.
Before building: A chemical treatment of the soil around the foundations and at the joints is the strongest and longest-lasting protection.
Around the building: Keep wood, leaves and construction debris away from the walls, and prevent water from collecting near the foundation.
Inside: Fix pipe and roof leaks right away, because moisture is what attracts termites.
The rule: An annual inspection by a specialist of the wooden and damp areas reveals an infestation early, before the damage.
Before Building
The easiest time to protect a building is before the foundations are poured:
- Soil treatment: With a chemical barrier under the concrete and around the foundations.
- Physical barriers: Metal mesh or resistant membranes at pipes.
- Site cleanup: Remove tree stumps and buried wood.
- Choosing the wood: Treated or resistant wood in the parts that touch the ground.
Around an Existing Building
An existing building can be protected with simple measures:
- Drainage: Slope the ground away from the wall and repair the gutters.
- Moving wood away: Keep firewood, outdoor furniture and mulch at least about thirty centimeters from the foundation.
- Raising the wood: Above ground level on a concrete base.
- Ventilation: For basements and under floors.
Inside
- Fixing leaks: As soon as they appear.
- Cardboard and paper: Do not store them on the floor or near a damp wall.
- Sealing cracks: Around pipes and floor joints.
- Checking used furniture: Before bringing it into the house.
Inspection Program
- At least once a year: Inspect the foundations and the lower wood.
- After heavy rain: Look for winged termites and wings.
- Record: Note any tube or pellets and photograph the spot.
- Renew: Renew the chemical barrier according to the product recommendation.
An Annual Inspection Map
A short checklist to inspect your home in twenty minutes:
- Foundations: Walk around the house and look for mud tubes.
- Doors and windows: Tap the lower frames with a screwdriver.
- Shed and storerooms: Cartons, wood and ceilings.
- Pipes: Under sinks and in laundry rooms.
Mistakes That Open the Door to Termites
- Storing firewood next to the wall: A direct bridge to the wood.
- Watering onto the wall: It dampens the soil at the foundation.
- Ignoring a small leak: One damp spot is enough to start activity.
- Sealing openings with paper or cardboard: It is itself food for termites.
Managing Irrigation and Drainage
Moisture near the foundation is the first invitation to termites. Direct drain outlets away from the walls, fix any leak in outdoor taps, and do not let irrigation systems wet the wall. For dripping air conditioners, run a pipe that carries the water to a spot far from the foundation.
Storage and Debris
- Do not store firewood, boards and cartons against the outer wall or directly on the ground.
- Raise stored items off the ground on metal or plastic shelves.
- Get rid of old tree stumps and leftover wood in the garden.
- Do not bury wooden construction debris when leveling the ground.
New Wood and Furniture
When buying wooden furniture or building lumber, inspect the piece before bringing it in: small holes, pellets or a hollow sound mean you should think again. Choosing treated wood or species more resistant to termites helps in the parts near the ground. In damp places, use non-wood alternatives where possible.
Annual Inspection Schedule
Set aside one day a year before the rainy season for an inspection round: the foundation from the outside, doors and frames, bathrooms and kitchens, the shed and roof, and storerooms. Write down what you notice and photograph it. If you live in an area known for termites, ask for a periodic professional inspection and do not rely on self-inspection alone.
A Maintenance Contract?
If the problem is large or keeps coming back, visit your nearest Orkida branch with a photo or a sample and we will point you to the right product. Before subscribing, ask what is included: the number of visits, whether a written report is covered, and what happens if the infestation returns after treatment. Do not accept absolute promises. A clear program that documents every inspection is better.
Products from the Orkida Store
We choose the treatment according to the type of termite and where the infestation is, and we recommend reading the dose and safety interval on the label before starting. For large infestations, it is better to use a specialist to apply the full barrier.
- Professional Termite Control Package for Homes: A professional termite package combining the specialized insecticide and application equipment, and it is the most suitable starting point for most homes.
- Premise 200 SC Insecticide for Termite Control, 1 L: Premise (imidacloprid) is non-repellent, so termites do not avoid it. They pass through it and carry its effect to the colony, making it a strong option around foundations.
- Biflex TC Insecticide for Termite Control, 1 L: Biflex (bifenthrin) is a repellent, fast-acting soil barrier at foundations and entrances.
What Should You Do If You Find an Early Sign?
If you spot a mud tube, a pile of pellets or wood that sounds hollow, it is best not to sweep or remove anything before photographing it. Photograph the spot from more than one angle, note the date, then call a specialist to inspect. Try not to move the infested furniture or carry it to other rooms, so you do not spread the infestation with it. Meanwhile, fix any nearby moisture source if there is one, and move cartons and wood away from the area.
Early detection can turn a major loss into a limited treatment, and that is the real value of regular inspection.
Frequently Asked Questions
Does the chemical barrier last?
It lasts for years depending on the product, the soil and the weather, and it needs periodic inspection.
Can I skip inspection after treatment?
No, because new colonies may arrive even after treatment.
Is treated wood enough?
It reduces the risk, but it does not replace moisture management and inspection.
Do natural methods help?
They may offer some simple local help, but they do not protect a building the way approved barriers do.

Frequently Asked Questions About Preventing Termites
What are the most important steps to prevent termites?
Eliminate moisture sources and water leaks, keep wood and cardboard from touching the ground, inspect the foundations and wood regularly, and treat the soil around the building when needed.
Is prevention enough once there is an infestation?
No. If signs of infestation appear, such as mud tunnels or hollow wood, direct treatment is needed, and prevention comes afterward to stop the return.
How often should I inspect the house?
Once or twice a year is preferable, especially in older buildings, damp places and wooden surfaces.
Is the chemical barrier in the soil useful?
Yes. It forms a barrier that keeps subterranean termites from reaching the building, and it must be applied the right way, following the label directions, or by a specialist.
