Moth Egg Killer Sachets - Trichogramma Parasitic Wasps

Number of Sachets

What are Clothes Moths?

The most prevalent Clothes moth in the U.K. is the Tineola Bisselliella. The larvae of the Clothes moth will damage many different types of garments, particularly those of natural origin: such as natural woolCarpets are also subject to attack and infestation. Warm, contained settings such as; wardrobescupboards 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 moths 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, hard to spot with the naked eye, but identifiable when they are situated on the outside of the packaging. They will 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.

New Moth Egg Killer Sachets Release More Wasps & Kill More Moths

Our brand new Moth Egg Killer Sachets have been designed for improved and longer lasting control of Clothes moth and other moth eggs.

Moth Egg Killer is supplied in a sachet containing the eggs of the tiny parasitic wasp: Trichogramma evanescens. Theses eggs hatch from the sachet over a period of 2-4 weeks releasing a continual supply of adult parasitic wasps into the surrounding area. The sachet has been developed with a focus on timed emergence with 2000 wasps emerging each week, providing you with sustained control over moth pests. It will usually take 2-3 days for the first adults to emerge. 

The longer lasting hatch rate increases the ability of the parasitic wasps to locate more moth eggs, and at that the correct time for when they can be successfully parasitised and killed. The Moth Egg Killer Sachets also release 3x the amount of parasitic wasps than our Clothes Moth Killer Egg Cards.

Sachets ideal for application to wardrobes, draws, carpets & rugs

Recent research has shown that the Trichogramma parasitic wasps like to fly upwards when they emerge from the sachets. For this reason the sachet has been designed without a hook so that it can be laid flat in the bottom of a wardrobe, placed in a draw, or placed on a carpet or rug. The wasps will walk out of the sachets first and spread out horizontally before they fly, so this also makes them ideal for application to carpets and rugs.

The sachets are supplied with a release hole on the top of the sachet, which is marked and already open. There is no need to open or cut the sachet. 

The benefits of Moth Egg Killer Sachets:

  • Sachets release up to 3x more Trichogramma than card introductions: up to 6,000 wasps per sachet
  • Sachets releases adult Trichogramma wasps for a longer period than cards: up to 3 weeks. This improves the effectiveness of Clothes moth egg control
  • Using these sachets reduces required introductions: replacing two weekly introductions of cards with one introduction of sachets a month 
  • Supplied as UK native species: Trichogramma evanescens

When should I use these sachets?

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 sachets?

The Trichogramma pupae are supplied in a paper sachet. Place the sachet on a horizontal surface at the site of infestation: i.e. on top of your clothing. Please be careful not to block the emergence hole. The wasps will emerge from inside the sachet and seek out the moth eggs. 

As the small adult wasps tend to fly upwards, place the sachet low.

Please do not open the sachets since the sachets are supplied with an emergence hole. Please also do not place objects on top of the sachets as you may damage the pupae inside.

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

How many do I need?

From each sachet 6000 parasitic wasps will emerge over a period of three weeks. The sachet is recommended to cover an area of 25m2.

We advise you to check pest numbers after application and consider applying more Trichogramma if numbers of Clothes moth remain high.

Can I store Trichogramma?

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


If you have Clothes Moth emerging from carpets, avoid hoovering entirely for 7-10 days after introduction of our Moth Egg Killer Sachets and reduce hoovering to a minimum for 3 weeks after application of sachet.

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.
