How to Protect Wood Fence from Termites – 7 Different Ways

Painting fence

Worried termites will lay waste to your new fence?

Worry not, you are not alone!

Research done on termites reveals that termite infestation is a common problem throughout the United States – particularly in the southern half of the country.

Termites usually spread through from the ground levels to reach your fences as well as wooden furniture at home.

They make use of termite tubes (that are made up of mud) to travel over non-wood items like concrete, brick, or metal.

Fortunately, there are several proven ways that can prevent (and help get rid of) termite infestation.

Painting and staining your wooden fence (or other infested articles) using high-quality anti-termite paint for wood are one of them.

In this guide, we’ll go over the different methods of painting a wooden fence that will protect against termites and give your yard an added aesthetic.

We’ll also see how you can use a paint sprayer to get the job done in half the time!

Keep reading to find out the best ways to treat your fence so that it stays termite-free and good-looking!

7 Different Ways to Termite-Proof Your Wood Fence

In general, termites do not tend to eat painted wood.

And the good part is from primers and paints to oil-based stains, there’s more than one way to paint and get rid of termites in your wood fence.

Let’s take an in-depth look at each of these ways so you can better fight off termites your way.

1- Use Termite-Proof Wood

While this may sound to be quite general, it’s one of the best ways to prevent termites, especially when you are building a new fence rather than staining or painting an already existing fence in your backyard.

Termite-proof woods like Redwood, Yellow Cedar, Laotion Teak, and Tallowwood are the best-known options for construction and avoiding the possible termite infestation.

However, since these types of wood are rare (may be unavailable or out of your budget) you can consider using a plank of pressure-treated wood.

These are easily available at your local hardware stores or lumber depots.

2- Use An Oil-Based Primer

If you plan on painting your pine or cedar fence, you should start off with an oil-based wood primer that’s designed specifically for protecting wooden surfaces.

These primers are designed to act as a termite repellant and are highly effective at keeping the nasty bugs away from your wood.

Remember that, for best results, you’ll want to apply two coats.

Make sure that the first coat of primer is fully dry before you apply the second.

3- Use Termite-Repellant Paint

Once you have applied the oil-based primer, it’s time to put on your final coat.

This finish comes in the form of termite-proof paint (on Amazon) that you can apply for even more protection against the pesky critters.

When painting, be sure to follow the manufacturer’s directions and keep in mind that you may need to apply two to three coats in order to get that quality protection (and look) that you’re going for.

4- Use An Oil-Based Stain

You may also choose to stain your fence if you are going for a more natural look.

Before you apply your stain (make sure it’s oil-based), you’ll want to coat your fence evenly with a wood sealer so that you add an extra layer of protection against termites and prep the fence wood for the stain treatment.

Next, you’ll want to apply your oil-based stain.

This stain will give the fence a more natural look and also prevent termites by allowing the oil to soak into the wood.

For best results, be sure to apply more than one coat of each, as this will allow you to reach deeper into the wood for better termite protection.

5- Apply Borate-Based Wood Preservative

Before you apply your paint or stain, you may choose to apply a borate-based wood preservative.

This solution, which comes as either a liquid you can apply or a powder you can mix with water, is highly effective at keeping termites at bay.

For optimal results, be sure to apply the borate wood preservative evenly and pour it into any post holes, as this will allow the chemical to seep into the surrounding ground areas and repel termites even more efficiently.

6- Use Termite Repellent Plants

Plant species like catnip and vetiver grass are effective to repel flying termites and can be used as a natural way to prevent termites near your fence area.

Marigolds, garlic, hot chili peppers, and mint are other few plants that help to deter termites (and vampires) from your garden.  

The good thing is some of these plants are so effective that they can also help in repelling aphids, moles, and fruit tree borers in your backyard.

7- Allow Easy Access to Sunlight

Bright sunlight and heat have the properties to kill termites.

If you are not interested in planting the termite-repellent plants you can clean the vegetation around your house fence which will then allow enough sunlight access to promote termite death.

How to Stain Your Fence with a Paint Sprayer?

Before going to steps, let’s quickly have a look – why you exactly need to stain your wood fence.

  • It refreshes the look and style
  • It prevents the rotting or pest infestations
  • It provides better endurance to seasonal changes and weather conditions

Properly staining the fence requires a little preparation if you want to do the job right.

Hence do not skip the preparation steps whatever the condition is.

Step 1. Fence Preparation

Clear out the workspace, cover the surrounding areas, and use a clean cloth or newspapers to ensure that any stain which does not hit the fence does not go anywhere it is not supposed to go.

You should start by removing all objects near the work area that might possibly be covered when using a paint sprayer.

So, outdoor garden furniture, plants in pots, and the like can be removed.

Plants and other vegetation along the fence will need to be covered to keep the stain from getting to them.

Although being outdoors means plenty of ventilation, you should wear a protective mask to keep from inhaling the fumes and odors generated from the wet stain.

This also means wearing gloves and clothing to protect the skin. You might consider specialized clothing that is easy to wash or simply throw away.

You may not be able to prevent all accidents or injuries, but you can minimize them to a considerable degree when taking the proper precautions.

Step 2. Cleaning & Checking the Fence

Now that you have prepared the area, the next step is checking the fence itself for any infestation.

If there are any termites seen make sure that you kill them before staining.

You’ll want to make repairs (like filling the nail holes, cracks, etc.) before you add the stain.

Plus, you’ll also want to remove or tighten any loose screws or nails in the fence itself.

Now you will need to clean the fence to ensure that you are not covering dirt or other debris.

For cleaning a wood fence before staining you can start by washing the fence and taking notice of any flaking paint.

Just remove all the old stain or paint that is loose. A good fence cleaner can be used to remove any additional debris if left behind.

Now when you have cleaned the fence for staining, you are ready to add the primer coating.

Step 3. Primer Coat

A primer coat will help the stain stick to the old fence. You will need to use a clean paintbrush and apply the coat.

This will take longer compared to using a paint gun, but it will ensure that that you cover all the fences.

As the primer coat dries, use that time to prepare the paint gun.

Step 4. Stain the Fence

Purchase the type of anti-termite paint/stain you want to use, pour it into the paint sprayer, and adjust the settings for maximum effect.

Remember to put the lid back on the can of stain before setting off to the fence. Now you are ready.

Aim the paint gun at the area of the fence you want to address first.

You should be about six inches to a foot away from the fence and spray according to how the fence panels are positioned.

  • For horizontal panels, spray up and down.
  • For vertical panels, spray back and forth.

Try to keep the action even and not to arc or curve when spraying or you might miss some areas.

Keep a paintbrush handy to correct any areas where the stain may puddle or gather. The brush will even such areas out.

How many coats you will need?

In most cases, you should not have to add a second coat of stain unless the coat you applied was too thin.

This can happen when diluting the stain so that it goes through the sprayer properly.

Otherwise, you can now relax and enjoy the day.

Step 5. Let the Stain Dry

Depending on how much stain you use, it will generally take about 18 to 24 hours before it fully dries.

This will depend on the temperature and weather conditions.

A warm, sunny day will mean it takes less, a cold, cloudy day means it will take longer to dry.

Be sure to look at the instructions on the can to see the expected time.

Step 6. Remove the Coverings and Clean the Tools

After you have stained your fence and it’s dried, it’s time to remove all the coverage from your plants.

If you used any plant cane and ties do remove them as well carefully.

Drying the stain before you remove the covering from plants is important as the wet paint can get in contact with the plants and can damage them.

Finally, when you are done do not forget to wash the painting materials you used (like sprayer, brushes, roller, trays, or any other).

Properly cleaning your tools using white spirit or thinner is important before you can store them.

This will help you preserve them in good condition for future use.

What Kind of Stain to Use for a Fence?

Remember, there are lots of products available on the market for staining fences.

Since not all of them are good enough, you will need to have your research done.

Make sure that you check for a product that is weather-resistant and can be used for exterior wood.

By checking the product information, you can easily figure out what exactly is the paint’s intended use.

The stains for fences (like DEFY, KILZ, Wood Defender, etc) are designed to be highly durable and can easily resist harsh weather conditions, no matter where you live.

Plus, you can easily wipe them clean with a soft cloth and lacquer thinner.

Many of these oil-based wood paints for fence painting are best suited for your rough sawn timber, cider, pine, redwood, spruce, and even pressure-treated wood.

Not only you can use them for protecting the wood fences but also for sheds, cabins, backyard wood storage, or any other garden wood.

Whichever brand name or product you pick, make sure you buy the right quantity that is enough to cover all the fence area you intend to paint.

If you are using a paint sprayer, you will also need to check that the stain you choose is good for spraying and can be easily sprayed over.

How Much Wood Stain Do You Need for a Fence?

If you know how much stain you will need before you make the purchase, you can save a considerable amount of money.

You’ll also save time and effort as well in buying what you need the first time.

What follows is an easy way to calculate the coverage and based on that how much stain you will need for your wood fence.

  • Measure the Height and Length of the Fence
  • Multiply the Height by the Length: This determines the square footage
  • Double the Result: If you are staining both sides of the fence

Now that you know the square footage that needs to be covered, you can now go to the store and read the can.

Most stains offer between 150 to 200 square feet per gallon, but this may vary so check the information carefully.

Divide the total square feet by the coverage that is found on the can.

This will determine how many cans you will need to stain your wooden fence completely.

If you have 1,000 square feet to cover and each gallon of stain covers 200 square feet, then you divide 1,000 by 200 and the result is five gallons.

Remember to round up all fraction results to ensure you are getting enough termite-resistant wood stain.

Should You Kill Termites in Your Fence Before Painting?

Yes, it’s important to treat the termites before painting if they are already present in your old wooden fence.

Most of the time homeowners think of removing and replacing the old infested fence as the only viable option.

IMO, if the fence is heavily damaged you should remove them and burn all the pieces.

Get the new one installed and follow the staining process (mentioned above) for protection.

However, if the fence is not heavily damaged and can be repaired you can kill termites and repaint the fence to make it like new.

So, how can you exactly get rid of termites in the wood fence before painting?

One of the best and most environmentally friendly ways of killing the termites in and around your fence is by using termite bait traps.

Remember, killing the termites that are present in your fence will NOT going to stop the termite activity completely.

You will instead need to detect the swarming termites (usually found inside the ground) and kill them for getting rid of them permanently.

Termite traps are basically the bait stations that are placed in or above the ground around your home (near the fence, deck, etc).

These traps do not actually trap the termites.

But it works by providing the bait (that may contain paper, wood, cellulose). These baits are combined with a poisonous substance that can actually kill the termites.

Spectracide Termite killer is one of the best termite baits that I have found and have been using for many years.

Not only it kills the termite fast but also it helps in detecting the termites very quickly around your fence.

Related Questions:

Is it better to stain or paint a fence?

When you are to choose between painting and staining a fence, I would suggest getting them stained rather than painting.

Since wood can absorb the stains to a much deeper extent than it does the paint, the finish you will get with staining will be excellent and longer-lasting.

Plus, it will also prevent the termites from eating through painted wood.

Can you paint over the stained wood fence?

Painting over the stained wood fence to protect it from bugs and insects would not be a problem if there are no signs of peeling paint.

However, if you see any dried-up peeling stain or signs of weathering you should remove the old stain properly before staining the fence fresh.

There are fence cleaners available in the market that can be used for cleaning and removing the stain.

How much does it cost to stain a wood fence?

The price to paint or stain your wood fence may range anywhere from $750 to $4500.

In general, it’s found that the cost may average $1 to $3 per square foot.

However, this will generally depend on factors such as the condition of your old fence, the height, the length, the quality of stain, etc.

The cost will also vary depending on whether you want to get them stained yourself or through a professional.

How often should you stain/paint your wood fence?

For most cases, you will need to repaint or stain your wood fence every 2 to 3 years.

This can be a bit more or less depending on what kind of wood you have, the type of stain you use on them, and the level of termite protection you seek.

Your exterior wood fence is exposed to all kinds of harsh weather conditions.

Mainly the moisture is the worst enemy that can damage your wood fencing earlier.

How soon you will need to repaint your fence will, therefore, depend on the specific weather conditions in your region.

For example, if it’s a region that gets heavy rains, you may need to spray your fence more often.

The same is also true for places with scorching hot days.

Regions with moderate climate will, however, require less frequent fence maintenance.

One of the best ways to figure out when it’s time for fence maintenance is to check for water beading.

On your properly stained and sealed fence surface, if the water does not bead up (but gets soaks in), it’s the best time for repainting.

You may also check for any cracks, chips, or wear on your fence to know whether it needs the repaint or not.

The Bottom Line

By using the right solutions, namely oil-based termite-proof paints and stains, you’ll be able to get your old wood fence properly treated for termites.

In fact, repainting or staining is one of the greatest ways to get rid of termites in a wood fence.

This will also help your fence’s aesthetic in the long term, as these solutions are highly effective at keeping the swarm of termites away from your wood.

Plus, it will also help in protecting the wood against the elements, such as UV rays (that causes greying of the wooden fence over time) and rainwater (that can seep in and can rot the wood or can create splits and cracks).

No matter what you choose to use, be sure to use a good paint sprayer for your fence staining work, as it helps to save time and get tough-to-reach areas with a clean and even finish.

In fact, using a paint sprayer is the fastest way to stain a fence as it allows you to evenly coat the entire surface very soon without wasting your time and energy.

Hopefully, by following the tips in this guide, you’ll be able to get that good-looking, termite-free fence in no time—with no hassle to boot!
