The food moth

It looks like a small butterfly in brown / gray tones; it is up to 25 mm wingspan and lives for about 2 weeks.

Her reproductive cycle is that of butterflies: a female can lay between 200 and 300 white eggs. After 4 days, the larvae are born and after about 1 month, after passing through the chrysalis (the cocoon), this results in a multitude of mites which are ready to feast on your foodstuffs in sachets. It can be born between 3 and 6 generations per year. The moth's development capacity is exponential.

It is important to pay attention to the condition of the food packaging (flour, sugar ...) and to change the container for glass, plastic.

The clothes moth

The textile moth, also called ringworm, is a small butterfly. The larva of this species can only complete its life cycle by feeding on animal fibers such as wool, hair and feathers.

The female prefers to lay her eggs in dark and quiet corners, near animal materials (eg wardrobe, storage room, chest, attic, etc.). The whitish eggs measure 0.5 mm and are very difficult to observe in the tissues. At birth, the small larva measures almost 1 mm.

When temperatures are 25 to 30 Celsius, the larva completes its cycle in 2 months. At the end of its larval stage, it measures almost 10mm. With the animal material on which it feeds, it will make a small cocoon in the shape of a tube.

The adult emerges after 1 to 2 weeks. It has atrophied mouthparts and is therefore unable to feed. At room temperature, the butterfly can live up to 14 days. Once mated, the female will be able to lay up to 250 eggs during her lifetime.

Keep your closets and cupboards closed

Inspect your second-hand clothes, which are generally less worn

Vacuum your wool rugs regularly

Please insulate the house well, as butterflies can enter through very small openings (ventilation, walls, etc.).
