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
Woodworm holes and burrows exposed in wooden floorboard. The first step in pest control is prevention. Particularly important in this respect is to keep the timber dry - below 16% moisture content. A relative humidity within the building above 60% may lead to an infestation, and timber moisture content below 12% is too dry for an infection to ...
The beetle does not infest wood that has recently died; about sixty years must pass for dead oak to reach a suitable condition for attack. [4] These beetles tend to stay on the same piece of wood for several generations until resources are used up and the piece of wood is no longer sufficient. [6]

With the water level lowered, the animals debark and the woodworm couple reunite. After all the animals and the humans left, the woodworms stayed behind inside the ark, which became their home for many generations. Over the course of time, the ark shrank down to the remains where the old woodworm still lives today.
The phenomenon can last from just a few seconds to 45 minutes, sometimes involving tens of thousands of individual birds. In Ireland, starlings’ numbers are boosted during winter, as migrating ...
In spite of their slender, worm-like forms, shipworms possess the characteristic morphology of bivalves. The ctinidia lie mainly within the branchial siphon, through which the animal pumps the water that passes over the gills. The two siphons are very long and protrude from the posterior end of the animal. Where they leave the end of the main ...
