Traitement des tissus à la perméthrine

Permethrin is a synthetic version of the Chrysanthemum flower’s natural insect repellent pyrethrin. The naturally occurring version breaks down rather quickly in sunlight but Sawyer’s pharmaceutical grade, synthetic Permethrin can last 6 weeks or 6 washings on clothing and other fabrics, making it a fantastic odorless barrier of protection from mosquitoes and ticks.

Non. La perméthrine n'endommage pas les vêtements ni le matériel. Contrairement au DEET, qui peut endommager certains tissus et matériaux, la perméthrine est compatible avec les tissus fragiles tels que la soie, ainsi qu'avec toutes les matières synthétiques et les membranes imperméables. La perméthrine n'affecte pas les plastiques ni les finitions. Sawyer® Permethrin Insect Repellent est inodore, non gras et ne tache pas après le séchage. La perméthrine peut être nocive pour les créatures aquatiques telles que les poissons. Ne vaporisez donc pas de perméthrine à proximité des aquariums.

Il est recommandé de traiter les vêtements avec l'aérosol de perméthrine à l'extérieur. Si le traitement est accidentellement effectué à l'intérieur, aucun effet indésirable sur la santé n'est attendu d'après les calculs de la dose inhalée. Toutefois, les personnes souffrant de problèmes respiratoires, tels que l'asthme, peuvent être plus exposées. L'odeur dégagée par le traitement des tissus à la perméthrine provient principalement des gaz propulseurs de l'aérosol plutôt que de l'insectifuge lui-même.

Une forte liaison se forme entre la perméthrine et la plupart des tissus. En fait, une certaine répulsion des insectes a été observée sur des uniformes militaires après 50 lavages. Cependant, les uniformes ont été traités par une méthode d'absorption au lieu de la bombe aérosol. Dans les études réalisées par l'armée américaine, environ 20 à 30 % du traitement à la perméthrine a été éliminé après le premier lavage. Par la suite, environ 3 à 5 % ont été perdus à chaque cycle de dix lavages.

Des études chez l'animal ont démontré qu'aucune irritation ou sensibilisation de la peau n'est attendue après une application directe. Dans une étude humaine contrôlée, la perméthrine n'a pas provoqué d'irritation ou de sensibilisation cutanée significative chez 200 sujets. Le port de vêtements traités à la perméthrine ne devrait pas avoir d'effets cutanés significatifs.

To apply Sawyer Permethrin, follow these step-by-step instructions for clothing and gear:

1. Preparation • Location: pick a well-ventilated area protected from the wind • Shake well before use, Permethrin tends to separate • Garment set-up: lay items out or hang them up, do not treat clothing while it is being worn
2. Application • Spray Technique: Hold the bottle upright 6–8 inches from the fabric surface. • Motion: Use a slow, sweeping motion to lightly moisten the surface of the fabric. • Timing: Treat each side of a garment (front and back) for approximately 30 seconds. • Coverage: Fabric should be well-dampened, often indicated by a slight color change or darkening, but does not need to be dripping wet. • Dosage Guide: Use approximately 4.5 oz. of Permethrin per complete outfit (one shirt, one pair of pants, and one pair of socks).
3. Drying and Storage • Allow items to fully air dry for at least 2 hours or longer, until fully dry. • Heat Bonding: While you should not put wet treated items in a running dryer, you can speed up drying by pre-heating an empty dryer, turning it off, and then placing the items inside. This heat helps the bonding process. • Extending Life: Store treated clothing in black plastic bags between uses to protect it from air and sunlight, which can extend its effectiveness.

Safety Notes • Skin Contact: Do not apply Permethrin directly to skin, face, or eyes. It is for clothing and gear treatment only • Pets: Permethrin is safe for dogs but is toxic to cats until it has completely dried. • Re-treatment: Retreat items after 6 weeks or 6 washings to maintain protection.

To treat your dog, first put a glove on one hand and spray with the other hand while fluffing dog hair, starting at the tail and moving toward the collar area. Spray rapidly to make sure the entire body is covered. Do not spray into the eyes and face - instead, spray a washcloth and wipe it. Pay special attention to the collar area, dog pit areas, and paws, as that is likely where a tick will try to attach. The dog does not have to be fully soaked. Avoid contact with genitalia. If the dog is super short-haired, you can also spray on a washcloth and wipe it on. For extra protection, you can spray your dog's bed, blanket, jacket, etc. It will last 5 weeks for mosquitoes and flea control and 6 weeks for ticks and other insects. Make sure to apply well before bedtime so that the product has time to dry. Do not use on puppies under 12 weeks.

Permethrin should not be applied near cats or aquatic animals. Cats have a very unique and sensitive central nervous system, and you never want to apply it to them or even spray it near them during the application process. However, once the treated clothing, gear, or fabric has fully dried, it is completely safe to wear/use around cats.

Yes, you can spray your clothing/gear with Permethrin outdoors, in a garage or in a storeroom and then bring them in to dry. If the sprayed items freeze, they will need to thaw out and completely dry before using/wearing in order for the Permethrin to bond to the fabric. You can also spray them in your house, just ventilate the area by opening a window or door and leave the room for a bit as you would not want to breathe it in.

Depending on the humidity, it should take between 2 to 4 hours to dry. Do not ever put them in your dryer when it is running, but to speed up the drying process, you can run your dryer while it is empty to heat it up, then shut it off and put your clothes in the warm dryer and leave them in there until dry. If necessary, you can repeat this process. The heat actually helps the bonding process and extends the life of the product.

Yes, Sawyer Permethrin is family-friendly. When fully dry and used as directed Sawyer Permethrin is safe for use around babies, pregnant women, and children. The Sawyer Foundation even equips global non-profits with Permethrin Baby Wraps, which reduces malaria infections in infants by 66%.

Spray the object, let it dry, spray again, let it dry, and spray again. If unabsorbed Permethrin drips off of the garment, catch the drippings and reuse. Apply as evenly as possible until the application is fully absorbed.

If you’re water proofing your own clothing, apply the water repellent first, then apply Permethrin using the process above.
