Moth
Classification
Order: Lepidoptera, Family: Tineidae
They do not pose a risk to human health, however they are pests that infest homes and professional spaces such as museums.
Their larvae are particularly harmful, as they cause serious damage to clothing, fabrics, furs, leather and carpets, destroying these materials.
An important observation is that damage to fabrics has usually already occurred before the flying adult insects become visible.
For this reason, it is necessary to take preventive measures to deal with moths, as when the adults appear, the damage has already been done.
Signs of infestation
Often the initial signs of a moth infestation are damage to fabrics, but there will usually be other signs:
Perfect moth insects (often crawling instead of flying).
Worm-shaped larvae (moth larvae).
Silky-textured tubes or pouches in which moth larvae live.
Nymphs-chrysalises (silk cocoons) within which the larvae transform into moths.
The main species
Common Clothes Moth (Tineolla bisseliella)
Wool and fabric moth (Tinea pellionella)
Hofmannophila pseudospretella
Perfect insects are 8-14mm long and brown in color with three or four dark spots.
Larvae up to 20mm long, pale yellow in color with a brown head.
The larvae feed on various animal fabrics, such as wool, leather, and feathers.
Endrosis sacritrella
Perfect insects are 6-10mm long, the head is white and has variegated wings.
Larvae up to 20 mm long, cream-colored with a reddish-brown head.
The larvae feed on various materials. They cause less damage to fabrics than other moths.
Treatment
It is difficult to completely prevent moths from entering a home through open windows or doors. However, we can take the following preventive measures:
Close curtains or use protective screens when windows are left open at night, as house lights attract moths.
Maintain high levels of cleanliness, as dirty or soiled clothes are particularly attractive to them.
Clean clothes before storing them.
Store fabrics for long periods of time in sealed plastic bags or suitcases.
Vacuum regularly under furniture to remove any eggs before they hatch.
Maintaining low humidity, repairing cracks and crevices.
Moths seek out dark and quiet places to lay their eggs, such as guest rooms, under beds, closets, attics. Particular attention should be paid to areas with bird nests where moths are attracted.
Before storing, each item of clothing should be checked for moths, washed, and placed in an airtight box or bag.
Insect repellents should be installed.
Hot method, Cold method, Dry ice smoking.
Repellents, insecticide sprays.
Mothballs are very effective but dangerous to health.
Lavender oils are not very effective.
Trapping is a relatively easy method that helps in monitoring and controlling the population.
Pheromone traps exist for Tineola bisselliella but not for Tinea pellionella.
If other methods cannot be applied when an infestation is detected, spray the clothes with an insecticide.
Be careful with petroleum solvent formulations, they may stain some clothes.
