Clothes Moth Egg Killer - Trichogramma parasitic wasps

Number of Cards

What are Clothes Moths?

The most prevalent Clothes Moth in the U.K. are the Tineola Bisselliella. The larvae of these Clothes Moth will damage many different types of garments, particularly those of natural origin; such as natural wool. Carpets are also subject to attack and infestation. Warm, contained settings such as; wardrobes, cupboards and airing cupboards also provide an ideal environment for the larvae to develop. The larvae often produce a silk web that is much larger than the larvae itself. Clothes Moth can be active all year round between the temperatures of 15℃ and 33℃.

What are Trichogramma Parasitic Wasps and how can they help?

Trichogramma are very small parasitic wasps, almost impossible to see with the naked eye. They seek out Clothes Moth eggs and lay their own eggs inside them, parasitising the Clothes Moth eggs. They are harmless to humans and animals and remain only for as long as there are Clothes Moth eggs present.

When should I use this?

Clothes Moths can be active all year round at indoor temperatures, and so too can these wasps. The wasps also require temperatures between 15℃ and 35.

How do I set up the cards?

The wasps are supplied in a carded dispenser which holds the Trichogramma eggs. The cards require no set up process, other than to be placed at the site of infestation; i.e. on top of your clothing. The wasps will emerge from inside the card and seek out the moth eggs.

Please ensure no chemical treatments have been used at 2 weeks prior to the introduction of Trichogramma.

Please do not cut the cards as you may damage the eggs inside. 

How many do I need?

Each card contains approximately 2400 eggs recommended to cover an area of 20m2. 

As the wasps only affect the moth eggs and not the adults or larvae, it is recommended that the cards are introduced at set intervals of 2 weeks (for 8 introductions) in order to completely break the life cycle of the moth.

Can I store Trichogramma?

As the wasps will hatch at ambient temperatures it is recommended that you do not store these cards. It is best to use them as soon as they arrive, opening in situ and ordering repeat cards fresh when needed.


If you have Clothes Moth emerging from carpets, avoid hoovering for 7-10 days after releasing Trichogramma parasitic wasps.

Gain complete control over Clothes Moth by also using our traps

It is also recommended that you first introduce our adult Clothes Moth Traps to assist in controlling infestations. The traps will contribute to reducing the number of adult male moths and prevent some moths from breeding. The traps also provide a visual indication of infestation levels.

Please do not release the Trichogramma wasps close to the traps. They will not be attracted to the traps but may fly in by accident and get stuck on the glue. Place the cards away from where you have set up your traps.

*Please order by 2pm Tuesday for despatch the following Tuesday (we do order surplus stock so your order will shipped sooner if possible)
