Moths

Protecting your home from moths

While moths do not pose a health risk, they are a pest in homes because of the severe damage their larvae cause to clothes, fabrics, furs, leather and carpets. This damage may continue for many weeks after moth caterpillars have hatched. Serious harm may have been done before numbers of flying moths are seen and so prevention of a moth problem is important. While a minor infestation of moths can be dealt with using DIY products, an established moth problem is likely to require professional assistance.

Signs of a Moth Problem

Often the first sign of a moth problem will be damage to fabrics but there will usually be other indicators:

adult moths (often crawling rather than flying).
maggot-like larvae (moth caterpillars).
the silken tubes or cases in which moth larvae live.
pupae (silk cocoons) in which larvae turn into moths.

Please note, another common cause of damage to carpets or fur may be due to fur beetles or carpet beetles rather than moths. Please refer to our guide to carpet beetles for further information.

Professional Moth Control

While DIY products can deal with smaller moth infestations, a professional pest control service will be required for larger or repeat infestations. Swift Pest Solutions technicians have a range of powerful insecticides to deal with moths and provide the reassurance that the problem has been fully dealt with.

Moth Species

There are four common species of moth infestation in the home:
Common Clothes Moth:

Adults 6-8mm with straw-coloured wings and no markings
Larvae creamy white with a brown head and up to 10mm long
The moth larvae make irregular holes in fabrics

Case Bearing Clothes Moth:

Found particularly with imported animal fabrics
Adults 6mm long with a dark-buff colour and three faint spots
Creamy-white larvae up to 10mm
Makes more regular holes in fabric than common clothes moth

Brown House Moth:

Adults 8-14mm and brown with three or four darker spots
Larvae up to 20mm, off-white with brown head
Larvae feed on a wide range of animal textiles including wool, leather and feathers

White-Shouldered House Moth:

Adults 6-10mm with a white head and mottled wings
Larvae up to 12mm, cream coloured with red-brown head
Larvae scavenge on wide range of food. Less damaging to textiles than clothes or brown house moths.
