Fragment of a broomstick affected by woodworm. Woodboring beetles are commonly detected a few years after new construction. The lumber supply may have contained wood infected with beetle eggs or larvae, and since beetle life cycles can be one or more years, several years may pass before the presence of beetles becomes noticeable.
Wood-boring insects can degrade the wood aesthetically by boring holes, and also indirectly as vectors for fungi and nematodes which can cause structural damage. [ 5 ] Allison et al. [ 11 ] extrapolated information from one mill in southern British Columbia to suggest that wood-boring insects could cause an annual loss of US$43.6 million per ...
Wood affected by woodworm. Signs of woodworm usually consist of holes in the wooden item, with live infestations showing powder (faeces), known as frass, around the holes.. The size of the holes varies, but they are typically 1 to 1.5 millimetres (5 ⁄ 128 to 1 ⁄ 16 in) in diameter for the most common household species, although they can be much larger in the case of the house longhorn beet
The Asian longhorned beetle is a wood-boring insect that attacks 12 types of hardwood trees in North America, including maples, elms, buckeyes, birches and willows. Infested trees do not recover ...

Here are some of the mot common bug, insect and spider bites you might be dealing with — and insect bite pictures to help you figure out what type of creature is responsible. Tick bites
Only for few species the larval biology is known. Orussidae are parasitoids of xylobiontic larvae of beetles or Hymenoptera, particularly of the larvae of jewel beetles (Buprestidae), long-horned beetles (Cerambycidae), and wood wasps (Siricidae, Xiphydriidae). [6] [7] Orussids can be observed running around quickly on dead tree trunks. The ...
Identification of which insect is present in interior timbers is difficult; by their nature, the larvae are tucked away from sight in their galleries. The presence of wood-boring insects may be indicated by frass (fecal residue) and fresh dust. Recent exit holes often have bright rims, while the rims of older holes have become dull.
