The webbing clothes moth is generally light yellow in colour and has a shiny lustre. The hind wings are grey-yellow and both fore and hind wings are fringed with fine hairs. The wings are quite thin and the wingspan is between 12 – 16 mm. The adult moths have a reddish-gold tuft of hair on the top of their heads. The larvae are a dirty yellow with a yellow-brown head and can reach a length of 7 – 9 mm.
Eggs are laid amongst fibres or scattered at random. Each female lays up to 160 eggs during a period of 2-3 weeks. During the summer these hatch in 4-10 days to give an active, white translucent larva. This grows up to 10mm in length and the head becomes darker in colour, there are at least 5 moults. The full cycle takes between 88- 254 days, depending upon conditions.
It is important to avoid conditions suitable for textile moths. Keep all wardrobes and clothing areas aired. All affected clothing should be thoroughly cleaned. Regular inspections of clothing should be done, looking for holes, larvae etc.
Frequent use of a vacuum cleaner, in wardrobes, storage cupboards and carpets can also help to reduce population numbers. Please always remember, after using a vacuum, to remove the collection bag and dispose of it in an outside bin. Clothes, fabrics, and linens that are not in regular use, should be stored in a sealed bag or wrapped in plastic.
Locate the source of infestation before treatment. Examine wardrobes and drawers for larvae cases, moths, and damage. Larvae prefer to feed in secluded, dark places. Look for signs of damage in carpets at the corners of the room and along edges, in stored clothing, and in other places not readily accessible.
Adult moths do not feed in fabrics but may be seen in darkened corners at night. Where old bird’s nests are present they should be removed and destroyed. Where necessary a residual insecticide can be applied to wall/floor and ceiling floor junctions and around carpet edges. If adult moth numbers are high a one-shot aerosol, smoke generator, or ULV treatment can be used as a quick knockdown
