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. Powderpost beetles are unlikely to infect structural timbers as these tend to be made from softwood. 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! Common furniture beetle, Anobium punctatum. Beetles have the basic insect anatomy of head, thorax and abdomen, but are characterised by a hard exoskeleton, hard forewings and abdomen with numerous hard plates. Anobiidae. Anobiid powderpost beetles attack sapwood but only rarely heartwood. This enables them to be active in daylight, unlike most moths. As indicated by their name, they are a pest of tobacco, whether it is in the shape of cigarettes or just stored leaves. The citrus longhorn beetle is a pest of over 100 species of tree and shrub. Whether you care about the books you have lying around your home, you should either store them properly- away from areas of beetle activity (remember, they can fly), or get rid of them. The life cycle ranges from three months to over one year, depending on temperature, humidity, and the nutritional quality of the wood. Imported tropical hardwoods are often infested with the beetles. The two most common families to invade wood are the Lyctidae and the Anobiidae. 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. Some species, however, break out into epidemics in forests with high densities of single species, killing trees over large areas. Carpenter ants are common in forested areas around the world, with 1000 species in the genus Camponotus. The females lay eggs on the rotten timber and the eggs hatch in 5-11 days. ANOBIID POWDERPOST BEETLES (Family Anobiidae). 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. The common products infested with the beetles include flooring, panelling, furniture and other hardwood items. 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). How to get rid of spiders in a woodpile Spiders take shelter because there’s plenty of food in woodpiles. Find out different prevention techniques to keep bees away, Learn to spot the signs of a bee infestation in your home. 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. The adults make a round exit hole about 10mm in diameter. This is described by many to be the worst problem encountered in the tobacco industry, attacking tobacco plants, cigars, cigarettes, as well as chewing tobacco. Cigarette beetles will nestle and eat books, book bindings, magazines, newspapers, and pretty much anything made out of paper. The larvae of all the beetles will reduce wood to a mass of very fine, powder-like substance, but the adults do very little damage. One more thought about cigarette beetles is that they belong to the Anobiidae family of pests and look quite similar to powder post beetles that bore into foreign woods (usually bamboo) and can cause damage to the wood it infests. The adult emerges by chewing an exit hole 6-12mm in diameter. The US Forest Service reports it has been detected in solid wood packing material in US ports. There are several families of wasp whose larvae bore in wood or takeover existing tunnels in wood made by other insects. In homes, they can feed off many food sources. Whilst in agricultural and rural settings, wood boring insects are responsible for damaging crops. They also establish satellite nests in drier wood that can contain workers, pupae and mature larvae. The females lay their eggs in cracks in the surface of wood or inside old exit holes. They also have the typical insect lifecycle of egg, larva with several stages of growth (instars), pupa and adult. 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. They also play a major role in making patches where new trees can regenerate, creating a more diverse forest ecosystem. The larvae mature in one to five years, depending on conditions, moving to just below the wood surface before pupating. 2430309 The false powderpost beetles infest hardwoods and some softwoods. They mainly target trees that are already stressed or damaged, such as from drought or injury. 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. The species well known in Europe, and the source of the name, is Xestobium rufovillosum. Unlike the lyctids, anobiids reduce wood to pellets, instead of a fine powder. 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. The larvae of this group pack their tunnels with a coarse, gritty frass, which distinguishes them from other types of wood borer. The parent colony can also be outdoors while the satellite colonies are in a building, with the ants constantly travelling between the two. Unlike termites they don't eat wood but use it to build their nests, Wood wasp larvae bore in wood, or takeover exisiting tunnels in wood made by other insects. The adult female of the Asian longhorn beetle chews a small pit in the bark to lay each egg. If you have spiders in hiding in your firewood, they can be a pain to deal with because spiders will bite when they feel threatened. The tobacco beetles also known as the cigarette beetles, or, scientifically, as Lasioderma serricorne  belongs to the order Coleoptera. 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. This group has recently been reclassified into a new subfamily of the Bostrichidae beetle family, called Lyctinae. Bark beetles can be pests of tree crops — in forestry and agriculture — and logs in storage or transport.
