Clothes/Food Moth Control with Trichogramma

T-gramma (Trichogramma) are tiny, parasitic wasps (less than 0.5mm) that are natural antagonists of the clothes/food moths. They feel most comfortable at temperatures above 20°C and are then most effective.

T-gramma can be used all year round. Simply hang the cards in your room or wardrobe and do not open the cards. The side opening is sufficient for the wasps to leave the card.

1 Card Treats 1 room, up to 25m²

Each card contains 2000 T-Gramma

How they work

Clothes and woollen carpets can be affected by larvae of clothes moth (Tineola bisselliella). Often the damage is only detected when it becomes visible or moths are seen flying around.

The eggs laid by the female moths are about 0.5 mm long, white and only hard to find in the fabric. The young larvae are about 1 mm in size and of yellowish white colour.

Clothes moths prefer dark and quiet hiding places in dry and warm rooms. During their lifetime, the females lay up to 250 eggs on textiles, fur or feathers.

The larvae feed on real wool, hair or feathers. From these materials the larva constructs its cocoon tube for pupation.

Clothes moths also infest carpets, fillings of old furniture, wall decoration, animal fur, trophies, etc.

The parasitic wasps have an excellent sense of smell and can localise the laid eggs by means of tiny parts of wing scales that the female moths lose when they lay eggs.

Trichogramma parasitic wasps are egg parasites, that is they look for the laid eggs of moths, lay their own eggs inside them and instead of a moth larva a new beneficial parasitic wasp hatches. This cycle repeats as long as there are moth eggs available.

The parasitic wasps are only interested in the moth eggs. Once the moth eggs are gone they die and disappear inconspicuously in the house dust. They are neither dangerous to humans or pets.
