14 Termite Prevention Tips

How do you prevent termites from damaging your home? They are called ‘silent destroyers’ because they may be tearing up your house without you noticing any signs of destruction.

So often you don’t know that you have termites. Still, there are various things you can do to inhibit the threat.

 

Experts estimate it generally takes 3 to 8 years for termites to cause considerable damage although some of the more destructive termite types can cause major structural damage in as little as a few months.

They are significant pests because of the severe damage they can cause to wooden structures such as your home, the fence, a barn or what not.

Termites can be very destructive

How to recognize a termite infestation

You can generally recognize a termite infestation by watching the insects swarm, by noticing “the flying ants in spring”,  by noticing the mud tubes they build as they forage for new food sources, the bubbling paint on the walls, and by noticing damaged wood where termites have been active.

  • Termites generally are about the size of ants, are white to tan in color, have long segmented bodies, round heads with two prominent antennae attached, and six legs.

 

How to Prevent Termites: 14 Tips

Below are 14preventive measures you can take to guard your house and property against termite infestations. You may use these tips to help keep termites away from your property.

1. Identify and fix all water leaks in your home, both inside and outside

Termites need water (even drywood termites need water), and if the water source comes from your home, the colony will not have to work as hard to get water. Eliminating their water source might induce them to look elsewhere to establish their colony.

  • Repair leaking water pipes, A/C units, and faucets.
  • Seal entry points around water and pipes or utility lines.
  • Divert water away the foundation of your home.

2. Eliminate any standing or pooling water from around your home

This might include installing French drains that allow water to percolate into the soil more quickly after a rain storm so it doesn’t pool near your home’s foundation.

It also means getting rid of standing water on the roof and other locations. This measure will help reduce mosquitoes in the yard too.

3. Keep all rain gutters and drain lines clean of debris

Gutters serve to efficiently convey water from your roof away from your home. Clogged gutters and drain lines leak, and allow water to pool in the gutters along the roofline and on the ground near the footers of your home. Make sure your gutters are serving their purpose.

4. Remove any brush or heavy growth from around your home

Vegetation can create areas of trapped moisture which termites can then use to support their colony. Vegetation can also facilitate a pathway for termites to find new wood to feed on (like your home’s wood siding).

Therefore, keep the area around your foundation raked and clean to enable proper drainage and keep your shrubbery trimmed back from your home’s exterior walls.

5. Seal potential access points

Proper sealing/caulking of any openings on the outside of your home can help limit the access to your home’s interior by termites.

Therefore, seal any holes, cracks, open seams, and fissures in places such as your foundation, footers, between siding boards and window-frames, etc.

Place screens on outside vents. Remove vegetation growing over vents.

6. Install physical termite barriers

There are various options:

  • Chemically treated soil (a.k.a. chemical termite barrier) around the outside of your home. Deadly to termites, safe for humans, pets and other animals. Generally, 3 types of chemicals are used; Fipronil, Bifenthrin and Imidacloprid. These are sold under the brand names Termidor, Premise, Prothor or Biflex.
  •  A physical barrier between the soil and the home often in the form of a stainless steel mesh. These barriers will help keeping termites at bay but are not 100% effective.
  • A combination of both in the form of a chemically treated physical barrier. For instance a layer of chemical-treated webbing sealed between two sheets of plastic.

 

7. Ventilation

Make sure your home is properly ventilated, including your attic and any internal crawl space areas. Adequate airflow prevents the buildup of moisture needed by termite colonies.

8. Remove dead trees, old stumps, or roots in your yard

As these decay, they provide food and habitat for termites. When the food is gone, the termite colony will look for new sources of food, including your house.

9. Never bury waste lumber or wood scraps in your yard

This will attract the termites and serve as a beacon for them to become established on your property.

10. Do not allow excess building materials or firewood to be stacked against your house

Remember, termites are attracted to wood. Why offer them an appetizer, and a bridge to a main course (your house)? Scrap wood touching the ground is an open invitation to hungry termites.

Keep  firewood at least 20 feet away from the house.

If your property is not large enough for wood storage away from the house, put a barrier beneath the wood to prevent direct access by the termites.

Stack the wood on a concrete slab or on a heavy metal stand that raises the wood off the ground (this will also help keep the wood dry and ready to be burned in your fireplace).

11. Use termite-resistant wood for any wooden structures that will have direct contact with the ground

Unprotected wood used for outdoor decks or landscaping is vulnerable to damage by termites. Over 90% of all termite infestations start from wood-soil contact.

If possible, keep an 18-inch gap between soil and your home’s wood structures.

Naturally termite-resistant wood types include redwood, cypress, and cedar.

Treated lumber includes pressure-treated pine, which is extensively used in the Southern U.S. for fences, decks, gazebos, etc.

Treated lumber is more long-lasting than naturally resistant wood.

The chemicals in treated lumber do not guarantee that termites will not invade the wood, but they can act as a deterrent for several years (whereas untreated pine might last just a few seasons).

Home improvement centers now offer concrete supports that raise the wooden support beams for decks and patios off of the ground.

You might also use composite boards in your deck or fence-construction in lieu of wooden boards. Composite boards are composed of woodchips and/or sawdust and plastic, and offer superior termite-resistance, compared to wood.

12. Avoid using mulch near your home

Mulch does two things for termites: (1) it provides a food source, and (2) it collects moisture, providing them with their water source.

If you place mulch too close to your home’s footers, it is only a small step for a termite colony to move from the mulch into your walls.

As an alternative to wood mulch, try using rubber mulch (made from shredded used auto tires). Rubber mulch provides the utility of natural mulch without the risks.

13. Periodically have your home inspected for termite damage

An annual termite inspection can save your home with early detection. Also, a trained pest control specialist can offer recommendations to help you prevent a termite invasion.

They also might find something that your own termite-prevention measures missed.

14. Special notes on Formosan Termite Prevention

The worst of any termite species is the invasive Formosan Termite, which is likely a native of southern China.

Formosan Termites have spread to many areas of the world, including the United States. These termites are subterranean termites, and what separates them from other subterranean termites and makes them much more dangerous to structures is their colony size.

A standard native subterranean termite colony might number a couple hundred thousand termites, while a Formosan Termite colony can number millions of termites.

They make a much larger infestation and can destroy wood at a faster rate. Their colonies extend for hundreds of feet underground from their food source, so this makes eradication efforts very difficult.

Formosan termite prevention includes all steps used for native subterranean termites, and one other thing:

Be on the lookout for extensive networks of soil-tubes climbing basement walls or other non-wood surfaces, which the termites build in their search for new wood to invade.

Types of termites

Termites in the United States are generally of four types:

  • Subterranean termites,
  • Drywood termites,
  • Dampwood termites,
  • Formosan termites.

Subterranean termites make their nests underground and emerge to attack wood they can easily reach. These termites are the most common cause of termite infestation.

Drywood termites remain entirely above ground and do not connect to the soil—infesting dry wood, such as structural lumber, dead limbs on trees, utility poles, decks, fences, lumber in storage, and furniture.

Dampwood termites are most often found in cool, humid areas along the coast, and infest decayed wood that remains moist from water contact.

Formosan termites are subterranean termites from Asia—now in 11 states in the U.S., and known to establish huge colonies that voraciously feed on the structures they attack.

  1. I thought that your tips were great! My husband and I recently moved into a neighborhood where termites have been known to cause damage to homes, so I’m glad I was able to find your post. I especially liked your tip to remove any dead trees, old stumps, or tree roots in my yard. I had no idea that these things, especially stumps, could house termites! There’s an old stump in our front yard, so I’m going to talk with my husband about removing it as soon as we can to avoid having any problems with termites in the future. Thank you for the information!

  2. There are some great tips in this post for preventing termites. After repairing my foundation from termite damage, I want to know how to prevent them from damaging my property again in the future. Your tips for being careful about where I place mulch is really helpful. I usually keep mulch against the back of my home to have easy access to it when I need to use it for gardening. Now that I can see that I shouldn’t be doing that, I’ll place it away from the walls of my home to prevent termites from using it as a food source and causing an infestation. Thanks for the tips!

  3. I have mulch in the flowerbeds closest to my home, and I had no idea that could contribute to our termite problem! I should probably change to rubber mulch, as you suggest. I will have my home treated for termites and then make sure to replace all the mulch! Thanks for the help!

  4. I didn’t realize that standing water could attract termites, so I’m happy that I read this article. The thought of having to deal with termites is terrifying to me and I want to avoid them at all costs. I will be sure to evaluate my home and make sure that it doesn’t seem at risk of termites coming and setting up camp.

  5. I can’t believe that 90% of termite infestations start from wood-soil contact. Honestly I didn’t even know that they lived in the dirt I just thought they somehow came from the wood. It is good that they offer termite resistant wood like redwood. Getting wood that already repels these bugs is better then trying to get termite treatment after. When I build a house we will be sure to get the resistant stuff!

  6. I did not know that termites needed moisture in the wood to thrive. Definitely checking for any leaks or standing water is a good start to pest control. I think it’s also a great idea to have a termite inspector come check the house a couple times a year. Thank you for the information!

  7. These are some great tips, and I appreciate your advice to cut back any heavy growth around your home to prevent termite problems. I noticed some piles of discarded wings on my window sill the other day, so I think we have a termite infestation. I’m going to have a professional come and take care of that, but I’ll definitely look into cutting back some of the plants against my house to make sure this doesn’t become a problem again in the future. Thanks for the great post!

  8. I never thought that cluttered rain gutters could cause termites! I wonder if that is where the ones in our attic came from. We discovered termites in our attic a few days ago and luckily, the damage isn’t too bad. We will have to keep these tips in mind while we look for a pest control service to come and help us out.

  9. okay I HAVE A MITE PROBLEM
