The adult powder post beetles carve holes in the woods when they emerge to the surface which can be lethal to not only the looks of the wood objects but also their longevity. With continuous infestations, the number of holes increases giving the wood a hole-riddled appearance. The structural integrity is hampered along with the aesthetic damages. The larvae, generation after generation further bore down the woods and turns them into sawdust with time.

An effective buying guide can help you to determine the ways to eliminate the root cause in the best possible manner. The most infestation prone object is an old wood surrounded by moisture. Outdoor storage of wood materials is often a cause for the infestation. Ensuring the wood objects to be kiln dry while buying reduces the risk of powderpost beetle infestation. Proper sanding and varnishing the same reduces the risks by a significant amount. Owners can further protect the wood materials by applying paint, varnish, and shellac to the unfinished end of the wood objects at home.

Maintaining the level of moisture below 12% effectively helps in ensuring the prevention of powder post beetles from damaging old wood items. You can install moisture barriers near the infested materials and objects for guaranteed resolution and killing of the beetles.

Natural Repellents to Get Rid of Powder post Beetles

There are some strong natural processes to get rid of powder post beetles. These natural processes are environment-friendly and at the same time can help you to get rid of powderpost beetles very quickly.

You must start with the correct intention and the right step

The powder post beetles prevention and management should begin right at the wood mill. However, pests can enter the product while it is being carried from the mill to your home. Thus you must thoroughly check all the wood products before you purchase them and take them home. You must fumigate the product if you see any signs of contagion before you carry them home. You must also check the firewood and bring only a particular amount that is necessary for that day.

Give them a drastic temperature change

If the powder post beetles enter into small objects and infest them, then the most effective and quickest way to get rid of them is to place the object at a cold location. Remove the item from the warm place and transfer it to any location which has a temperature less than 10 degrees Fahrenheit. Leave it at that temperature for almost 72 hours.  To check the effectiveness of this process remove the item from the cold place after three days and place it back to the previous location where the temperature is high as compared to the colder place. Keep it in the warmth for about two days. Repeat this process again to ensure the object is free of powder post beetles. The beetles are killed not because of the cold temperature rather due to the drastic change in temperature. They get eliminated and cannot cause any further damage to your furniture or any wooden object.

You can kill the powderpost beetles by placing them over a kiln

There is a particular guideline which must be maintained to kiln-dry any object. You can apply this process only on large pieces and small objects of wood like beams or boards. The heat generated consistently will kill the beetles, but you cannot keep them away with the help of kiln-dry. You must seal the wood or paint it when it is dry.

You must not give them an opportunity to grow

Powder post beetles are attracted to dry and old wood. If you have old wood close to your house, it is most likely that powder post beetles will spread in these wood and in turn enter your house and affect your furniture. You must keep your property clean of dead tree limbs, branches, and wood scraps. By doing this, you are taking away the greatest option of the beetle entering your home.

Provide them with air and reduce the moisture content

Low moisture level in wood is against the survival conditions for powderpost beetles. You must check that the moisture level in all wooden objects at your home has low moisture level. They will die where the wood does not have a minimum moisture level of 20 percent. You must increase the air supply and ventilation or place a moisture barrier if your furniture or any other wooden object is exposed to moisture.

You can use some salt

Borate salt is a common and easy way to treat powder post beetles. This process is not meant for thick and dry wood as the borate salt cannot penetrate deep inside the wood. However, it works on thin wood, and you can see the difference if you sprinkle some salt on the wood.

Throw away the infested wood and replace it with a new one

This process is not quite possible in case of large furniture. However, if the infested area is small and involves wooden paneling or molding, you should consider replacing them.

Apply essential oils

A study was conducted in the year 1993 which proved that eucalyptus, basil, and tarragon oil could help in getting rid of powder post beetles. The beetles got killed within 72 hours according to the research result. There were other oils as well but did not show much effect.

Cedar oil is considered to be the best natural repellent. It not only kills powder post and many variations of these beetles but also helps in repelling them.

Apply finish to all wooden work done at your home

Wooden furniture and other objects attract powderpost beetles if left unfinished. You can use shellac, paint or varnish on the surface of the objects, so that female powder post beetles do not get an opportunity to lay eggs on the unfinished surface of the objects.

DIY Repellents to Kill Powder post Beetles in Home

You can follow these processes to get rid of powder post beetles and their infestations.

You must reduce the level of moisture present in the wood and maintain it at 20 percent. You can use a moisture meter to determine the level of moisture present in the wood. You can place vapor barriers, central heat and have a good ventilation system to control the level of moisture. Any lumber that has been rough-cut must pass through kiln so that any powderpost beetle or larvae present gets killed.

You need to apply varnish or get the wood sanded as maintaining moisture level will not be a complete solution. The powderpost beetles do not get attracted to sanded wood. The beetles cannot find cracks in order to penetrate and lay eggs on the surface of the wood.

You must shift your valuable belongings away from barns and sheds if they are near to any as powderpost beetles are found in these areas.

You can apply wax, varnish, and paint to seal it from infestation. You can use boracare or Timbor to treat the unfurnished furniture so that larvae do not enter the wood.

In case the furniture is already infested you can treat it in a fumigation chamber to get rid of these beetles.

The best possible way is to remove the wood that has been infested with the powder post beetles. There can be beetles seen emerging from the wood structure even after the elimination process has been conducted; this is mainly because of the action that the repellants impost on the beetles. The solution and powder repellants often stick deep as residues on the surfaces, as well as in the inside of the wood structures and remain there along with serving its effect usually for a couple of months to a couple of years depending on the power of disinfection.

The primary point to be noted while using an insecticide is that the lifespan of the powder post beetles often stretches over a period of three months to one year. The wood must not be too dry as the solutions for disinfecting the infested regions will not be able to properly penetrate deep and impose its action on the powderpost beetles. Adding water to the solutions and the sprays accurately help in the process of penetration and reaching to the deep inner parts so that the hidden powderpost beetles can be effectively killed and eliminated.

For certain cases, where the infestation levels are high, and you do not want to replace your valuable wood material; fumigation is the only way that can help. This is generally a costly process but has a full guarantee of eliminating and killing the powder post beetles by exposing the material or space under the highly packed action of gases for a long span of time. The process involves the use of harmful gases that can be toxic to humans and animals nearby.

Ways to Control Powder Post Beetles

You can remove infestations when a small or limited area is affected by these powderpost beetles. However, if you see holes appearing in other places, you must consider going for pest control on an immediate basis. You can apply insecticidal processes to the surface of the wooden items remains exposed to moisture and have a greater chance to get affected by powder  post beetles. However these insecticidal is not enough to get rid of the beetles completely as they are not able to reach the larvae of the powder post beetle burrowed deep inside the wood. Thus this treatment process has some limitations.

You can treat the surface of the wood with insecticides, and they will have residual effects so that re-infestation does not occur and the adult beetles get killed as soon as they emerge on the surface of the wood. You can use essential oils and extreme temperature effects to eliminate the powderpost beetles. However, you can use formulas that contain borates as it will penetrate into the woods and kill the larvae at the core of its dwelling place. If the powder post beetles persist after using DIY and other natural methods you should get in touch with a pest control company and allow the experts to eliminate these pests from the roots s that they do not return. They will not only control the population of powder post they will also take precautions that are necessary to prevent recurring of the infestation.
