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

Trombiculosis is a rash caused by trombiculid mites, especially those of the genus Trombicula (chiggers). The rash is also often known as chigger bites.. Chiggers are commonly found on the tip of blades of grasses to catch a host, so keeping grass short, and removing brush and wood debris where potential mite hosts may live, can limit their impact on an area.
The mite parasitizes a variety of insect hosts and is able to bite humans, causing red, itchy, and painful wheals (welts). The mites are barely visible, measuring about 0.2–0.8 millimeters; their great reproductive potential, small size, and high capacity for dispersal by wind make them difficult to control or avoid.
A human host usually notices the bite within several hours, and the itching is most intense the first one to two days. Chigger bites usually slowly go away after two weeks, per the Cleveland ...
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 ...
