REVEALED: Surge in moth infestations in Irish homes

A surge in moth infestations in Irish homes has been reported.

A 42% increase in callouts for brown house moths nationally in February 2024, compared to February 2023 have been recorded.

The onset of spring typically signals heightened activity among textile moths, including species such as the brown house moth.

These pests pose a significant threat to household possessions, as they feed on fabrics containing keratin, such as wool, fur, and silk. They commonly infest undisturbed areas like spare bedrooms, infrequently used wardrobes and attics.

However, moths can also wreak havoc on clothes, carpets, curtains and upholstery and can cause irreparable damage.

To help mitigate the risk of a moth infestation, pest control company Rentokil advises homeowners to undertake spring cleaning measures.

By cleaning and properly storing winter clothes, employing fly screens and maintaining cleanliness through regular vacuuming, individuals can proactively prevent moth eggs from hatching and infestations from taking hold.

Colm Moore, Area Technical Manager for Rentokil, said: “There are several steps that people can take to guard against the presence of moths in their homes. 

“Always ensure that clothes are clean before storing them – soiled and dirty clothes are more likely to attract moths. Use fly screens or keep curtains drawn at night to help prevent moths from entering your home. 

“Be aware of old textiles that may be stored for long periods in attics and wardrobes. These items may be harbouring long-seated infestations. Also, be aware that old bird nests in attics may also be harbouring textile moths and other invertebrate pest population(s).”

There are four commonly found species of textile moth found in Ireland each with a preference for different textiles, and each varying in the damage that they cause to materials:

• Common clothes moth causes irregularly shaped holes in textiles.
• Brown house moth larvae are attracted to animal-based materials such as feathers and leather.
• Case-bearing clothes moth larvae cause smaller and more regularly shaped holes in textiles.
• White-shouldered house moth larvae are less damaging to textiles as they scavenge a wide range of food.
