Signs of a wood borer infestation-How to Identify Signs of Wood Borers ?
You may not realise that you have a wood borer problem until the damage becomes visible, so an early identification is the key before more harm is caused.
Wood borer life cycle ?
There are four stages of wood borer development-Egg -Adult beetles will lay in cracks of wooden objects, floorboard and timbers.Larva -Once hatch, they immediately burrow through the timber, making it very unlikely they would be seen. They safely hide inside the wood, continue to tunnel and feed on wood for several years.Pupa -Once larva matured and increase in size, they bore towards wood surface to pupate.Adult- Emerge as adult on wood surface.
Signs of wood borers ?
Eggs - found in cracks of wooden objects, floorboards and timbers.Wood borer larvae - usually a creamy-white colour and curved in shape.Bore dust / frass - caused by emerging adult beetles, usually visible below the infested wood.Weak and damaged floorboards - in extreme cases, a foot or chair leg going through the floor can indicate a more serious problem.Crumbling wood - around corners or edges of floorboards.Tunnels in the wood - also known as 'galleries' which are often hard to see.Dead borers - usually found near the infested wood or around nearby windowsills.Exit holes on wood - round or oval shaped with sharp edges, the holes will appear clean and fresh.

How to get rid of wood borer ?
When a wood borer infestation is left untreated, they can potentially develop into a serious issue, such as damaging wooden floors, door and furniture. The following step will help discourage wood borer infestations-Wood boring beetles are attracted to the moisture content in the wood, try to keep furniture, door and wooden items dry. Seal cracks and crevices on wood surfaces to deter wood borer from breeding. Remove infected wood to avoid the infestation from spreading to another area.
Wood borer species ?
Wood damaging pests can attack expensive antiques and even a building’s structural components. Knowing the type of wood boring beetles involved can help determine the most effective control methods.
House longhorn beetle-(Appearance)-Adult beetle is 8-25mm in length.Black/brown colour with grayish hairs and 2 black spots on thorax which resemble eyes.
Life-cycle-Larvae tunnel between 3 to 11 years before emerging.(Habits)-Flight holes between 3mm and 7mm.Infests seasoned and partly seasoned softwoods; pine, spruce and fir most susceptible.It is frequently timbers used in the roof space that are infested.Damage can often be severe in timbers around the chimney area. The larvae produce large amounts of bore-dust (or frass) containing cylindrical pellets. Sometimes this is visible in the 'blistered' appearance of the surface wood.Longhorn beetles will fly freely in hot, sunny weather which enables them to spread an infestation from one building to the next.
Powder post beetle-(Appearance)-Adult beetle is flattened and elongated with 1–7 mm in length.Reddish to dark brown in colour. Larva is white in colour, slightly curved and can measure up to 5mm when fully developed.Newly hatched larva is straight, extremely slender and less than 1 mm long.Life Cycle-Under favourable condition, it takes 9–12 months to fully develop.Adult lives 1–3 months.(Habits)-Usually attacks wood that is dry, untreated with chemicals and rich in starch, namely Rubber wood, Ramin, Jelutong, Penarahan, Merbau and Kempas.
Wood boring weevil-(Appearance)-Adults are 2.5 to 5mm in length.The weevils are reddish brown to black. They have a long snout, a cylindrical body and short legs.The larvae are a creamy white C-shaped, wrinkled and legless.Life Cycle-Adults are 2.5 to 5mm in length.The weevils are reddish brown to black. They have a long snout, a cylindrical body and short legs.The larvae are a creamy white C-shaped, wrinkled and legless.(Habits)-Damage is associated with damp and decaying wood, particularly timber already rotted by cellar fungus. Infestations can spread to adjacent healthy wood.
Common furniture beetle-(Appearance)-Adult beetle is 3 – 4mm in length.Life Cycle-Larva will live for 3 - 5 years boring through timber before emerging to breed.(Habits)-They actively fly in warm sunny weather.Within homes and other buildings the furniture beetle is an exceedingly common pest.Despite its name this beetle can invade more than just furniture.Infestations can damage decorative woodwork, musical instruments, wooden tools and on a more serious scale wood flooring, joinery and structural timbers.These wood boring beetles consume hardwoods and softwoods.
Wharf borer-(Appearance)-7–14mm in length.Yellow brown with tips of elytra (wing case) black.3 ridges along the length of the elytra. Life cycle-Eggs are laid on damp, decaying timber.Larvae bore through wood for about 9 months then emerge in Summer.(Habits)-Larvae require wood to be constantly wetted so that fungi break down the wood fibres.Two main sources of infestation in buildings-structural timbers where rainwater leakage occurs, and pieces of timber buried below concrete foundations, paths and pedestrian precincts.
Wood boring insects-Wood boring insects refer to a selection of arthropods which cause damage to wooden structures. This group of insects feature a range of species of insect at different stages of their life cycles from larvae to adults.Wood boring insects are seen as pests due to the damage they create in both urban, and rural areas. Within an urban environment wood boring insects can cause a huge amount of damage to residential properties. Whilst in agricultural and rural settings, wood boring insects are responsible for damaging crops. However, it’s worth noting that some wood boring insects are a key part to the ecosystem, helping to recycle dead trees. There are some cases though where wood boring insects have become an epidemic in some forests killing a large amount of trees.
Beetles-Beetles are the largest group of animals, having about 400,000 species in 500 families. They are extremely diverse with species adapted for almost any kind of environment and to feed on any food source, including many agricultural, horticultural and forestry plants and products. Many species are also beneficial predators of other insect pests.Beetles have the basic insect anatomy of head, thorax and abdomen, but are characterised by a hard exoskeleton, hard fore wings and abdomen with numerous hard plates. They also have the typical insect life cycle of egg, larva with several stages of growth (instars), pupa and adult.
Woodworm-Woodworm is a generic term used for a number of species of wood-boring beetle and refers to the larvae of the beetles, which feed on wood after hatching from the egg, creating tunnels in the process. They only emerge from the timber after pupating and developing into adults, creating the characteristic holes in the wood surface.This characteristic also leads to the misconception that the holes can be treated with insecticide to kill the beetle, when in fact it is pointless as the hole signifies that the beetle has left!The main beetles that cause damage to structural timber and wooden fittings, furniture and items in buildings are classified into three groups, commonly called: deathwatch (Anobiidae family), powderpost and false powderpost beetles (Bostrichidae family).
Anobiidae-(Deathwatch beetle)-Several genera and species of beetle in the Anobiidae family are called deathwatch beetle. The species well known in Europe, and the source of the name, is Xestobium rufovillosum. In the US, however, the Pacific deathwatch beetle Hemicoelus gibbicollis is the most common in California, while in other parts of the world Xyletinus spp and Ptilinus ruficornis are called deathwatch beetles.The beetles get their name because of their habit of tapping on wood, usually at night, to attract a mate, which in European folklore was associated with the ‘grim reaper’ tapping on his scythe to announce an impending death.
Deathwatch beetles mainly infest moist and partly decayed softwood timber that has moisture content over 14%. They are more likely to be found in damp buildings or areas of buildings with poor drainage or water leaks. They are unlikely to be present in buildings with central heating where the moisture content is low.The beetle larvae fill their tunnels with frass that has a slightly gritty texture, but less coarse than false powderpost beetles. The exit holes can be of varying sizes, but are larger than powderpost beetle holes.
Common furniture beetle-(Anobium punctatum)-The furniture beetle only infests dry, seasoned sapwood of hardwood and conifer trees. It causes more damage in structural timbers and joinery than in furniture. The females lay their eggs in cracks in the surface of wood or inside old exit holes. The eggs hatch into larvae in a few weeks and bore into the wood. The larvae mature over 3-4 years, eating their way through the timber. After pupating near the surface of the wood the adults make an exit hole 1-1.5 mm in diameter. An active infection is shown by the presence of wood dust around holes. As the larval stage lasts several years there can be an active infestation with no visible signs during this period. The actual time of development to the adult depends on type of wood, temperature and humidity.
Wood wasps-There are several families of wasp whose larvae bore in wood or takeover existing tunnels in wood made by other insects. The main family that attacks trees is the Siricidae, or horntails, named because of a horn like feature on the abdomen of the larvae.The female wood wasp has a needle-like ovipositor that it uses to drill into a suitable point in the wood of dead or dying trees to lay the eggs. It also squirts a fungus-containing liquid onto the wood that digests the wood for the larvae to feed on. The eggs hatch into larvae in three to four weeks and tunnel into the fungus-digested wood as they feed on it, usually parallel with the grain, resulting in a tunnel about 25-30 cm long. The larvae mature in one to five years, depending on conditions, moving to just below the wood surface before pupating. The adult emerges by chewing an exit hole 6-12mm in diameter.
The wood wasp lays eggs in already damaged trees, but the introduced fungus can rapidly deteriorate the timber. It will not infest wood in homes, but can be brought into homes in finished timber. The damage to buildings caused by wood wasps is mainly cosmetic, resulting from their exit holes in timber, but also through other substances covering the timber, including plaster, linoleum, carpets, and other flooring materials.One species of wood wasp, Sirex noctilio, is regarded as an invasive pest. It is native to Europe, Asia and north Africa, but has been introduced to the US, New Zealand, Uruguay, Argentina, Brazil, Chile and South Africa, probably through international trade involving timber. The US Forest Service reports it has been detected in solid wood packing material in US ports. In its native areas it is a secondary pest of pines, but in other countries it has caused extensive mortality in plantations of pine species introduced from North America.
Bostrichidae-There are more than 700 species in the Bostrichidae family, which includes a number of common wood and also food pests in both temperate and tropical regions.
False powderpost beetles-The false powderpost beetles infest hardwoods and some softwoods. Tropical timber and bamboo transported in international trade are often infested with the beetles. The common products infested with the beetles include flooring, panelling, furniture and other hardwood items.The females do not lay their eggs on the surface of the wood, but bore a ‘gallery’ into the wood to lay their eggs in pores or cracks. The larvae of this group pack their tunnels with a coarse, gritty frass, which distinguishes them from other types of wood borer.
Powderpost beetles-This group has recently been reclassified into a new subfamily of the Bostrichidae beetle family, called Lyctinae. It was previously in a separate family, Lyctidae. Powderpost beetles tend to attack the sapwood of certain hardwoods and bamboo that have large pores in the wood in which they can lay their eggs and that have a high starch content, such as oak, ash, walnut, mahogany. Imported tropical hardwoods are often infested with the beetles. Hardwoods with smaller pores such as birch and maple are rarely infested and softwood, which is from conifers and has lower nutrients, is never infected. The beetles also prefer dry wood, feeding on wood as low as 8% humidity.The starch content reduces with the age of the timber, therefore powderpost beetles are rarely found in old timber. They are more common in new homes and recently manufactured hardwood items such as window and door frames, panelling, flooring, plywood and furniture.
Powderpost beetles are unlikely to infect structural timbers as these tend to be made from softwood. Wood that has a finish, such as paint, varnish, or wax will not have a new infection, but the beetles can already be present when it is processed and can still emerge later.These beetles are called powderpost because the larvae produce a characteristic fine, dust-like frass with the consistency of flour or talcum powder, as they feed on the wood and bore the tunnels. This distinguishes them from other types of woodworm.The adult females lay their eggs on the surface of wood or in cracks. The life cycle ranges from three months to over one year, depending on temperature, humidity, and the nutritional quality of the wood.
Longhorn beetles-(Old house borer, house longhorn beetle)-The old house borer, Hylotrupes bajulus, is native to Europe but has been spread to many areas worldwide through the trade in timber and wood products. It is a pest of seasoned sapwood of softwood timber. It is more often found in new homes, infesting younger timber, rather than timber in old buildings. The life cycle takes up to 10 years, depending on environmental conditions and the nutrient content of the wood, which decreases with age.Infestation in homes is caused mainly by using timber already containing the eggs or larvae. They feed on the wood, mainly near the surface, until maturing into the adults. The larvae are larger than many wood boring larvae, up to 2.5 cm long and they cut larger exit holes 6-10mm in diameter.
Anoplophora-( longhorn beetles)-The Asian longhorn beetle (Anoplophora glabripennis) and citrus longhorn beetle (Anoplophora chinensis) are native to East Asia but have been introduced to other areas of the world, most significantly Europe and North America. The Asian longhorn beetle is a pest of hardwood trees in roadside plantings and plantations in China and has now become a pest in Europe and the US. In the US it tends to attack Acer species. The citrus longhorn beetle is a pest of over 100 species of tree and shrub.In the UK and the US the early discoveries of the beetles were related to plants imported from China and Korea. Both species are listed in the EU Plant Health Directive, while in the US the Department of Agriculture and the Forest Service ask for notification if the Asian longhorn beetle is spotted.The adult female of the Asian longhorn beetle chews a small pit in the bark to lay each egg. The larvae feed within the vascular layers of the tree: the citrus longhorn in the lower part of the tree and the Asian longhorn in the upper trunk and branches. The adults make a round exit hole about 10mm in diameter.
Bark beetles-(Ernobius Mollis)-Bark beetles are now regarded as a specialised section of the weevil family, the Curculionidae, in the subfamily Scolytinae, which has about 6,000 species in 220 genera.Bark beetles can be pests of tree crops-( in forestry and agriculture)and logs in storage or transport. They introduce fungi that attack the wood, killing the tree or introducing decay in stored logs. In the US, where many native species are important pests of conifer trees, the US Forest Service has also recorded 53 invasive species that are thought to have been introduced through international trade.In natural forests, bark beetles are important in recycling weakened and dying trees and creating habitats for other insects and fungi. They also play a major role in making patches where new trees can regenerate, creating a more diverse forest ecosystem.The female lays the eggs in the phloem layer, the moist inner layer of the bark next to the sapwood. Some species mine a short chamber in the bark for depositing the eggs or also mating. The larvae feed on the phloem layer, leaving characteristic patterns of tunnels in the outer wood of the tree.
Moths-The larvae of some species of clearwing moths of the family Xyloryctidae (Australia) and Sesiidae (Europe, North America, tropics, Australia) are important wood boring pests in ornamental and timber trees. There are over 1300 species of Sesiidae, many resembling wasps and hornets, in both looks and behaviour. This enables them to be active in daylight, unlike most moths.The females deposit the eggs in crevices or broken bark and after hatching the larvae burrow into the bark and sapwood of the tree. They mainly target trees that are already stressed or damaged, such as from drought or injury. In the US, clear wing moths infest alder, ash, birch, fir, oak, pine, poplar, sycamore, willow and several types of fruit trees. Commercial products containing nematode worms that are parasites only of the moths are available to control outbreaks.
Carpenter Bees-There are around 500 species of the carpenter bee, Xylocopa, nearly all building nests in dead wood or bamboo. They are often similar in size and appearance to bumble bees, but are distinguished by having a hairless, shiny upper abdomen.Carpenter bees do not eat wood, the adult female bee excavates tunnels 3-6 inches long in the wood to lay the eggs. The eggs are laid in a set of small cells in branching tunnels, or separated by a thin sliver of wood along a tunnel, each provided with a ball of pollen on which the larvae can feed. The entrance hole is perfectly round, about half an inch diameter-the size of a finger. The female can enlarge old tunnels or create new ones for egg laying. The bees are generally solitary, but can ‘cohabit’ or nest in groups.When a bee is active there may be coarse sawdust beneath the entry hole and scraping sounds heard coming from within the wood. Carpenter bees prefer bare or weathered wood, so painted or treated wood is a deterrent.
Carpenter Ants-Carpenter ants are common in forested areas around the world, with 1000 species in the genus Camponotus. They do not eat wood but build their main nests by tunnelling in damp wood where the moisture is high enough for the eggs to survive. They also establish satellite nests in drier wood that can contain workers, pupae and mature larvae. One species, the black carpenter ant (Camponotus pennsylvanicus) is one of the most common pests in homes in the US.Carpenter ants will readily invade buildings to forage for food and establish nests in wood that provides the right environment for colonies-such as wood that is kept moist by leaks, condensation or poor air circulation.
They also nest in any small spaces in a building with the right moisture conditions, such as behind bathroom tiles or round badly fitting window frames. The satellite nests, which require less moisture for the colony to survive, can be established in almost any void in a building.The parent colony can also be outdoors while the satellite colonies are in a building, with the ants constantly travelling between the two. Carpenter ants can be large ants, 0.3-1 inch, but even within a colony there are different sized ants with different roles.The ants feed on protein, often dead insects, and carbohydrates, especially the honeydew produced by aphids and scale insects. In homes, they can feed off many food sources.
