Tratamiento de tejidos con permetrina

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.

No. La permetrina no daña la ropa ni el equipo. A diferencia del DEET, que puede dañar algunos tejidos y materiales, la permetrina es compatible para su uso incluso en tejidos frágiles como la seda, además de todos los tejidos sintéticos y de membrana impermeable. La permetrina no afecta a los plásticos ni a los acabados. EN CASO DE DUDA, pruebe una muestra en una superficie poco visible, especialmente en prendas delicadas, y compruébelo tras 24 horas de exposición.Sawyer® Permethrin Insect Repellent es inodoro, no graso y no mancha después de secarse. La permetrina puede ser perjudicial para las criaturas acuáticas como los peces, por lo que no debe pulverizarse alrededor de acuarios de peces.

Se recomienda que el tratamiento de la ropa con el aerosol de permetrina se realice al aire libre. Si el tratamiento se realiza accidentalmente en interiores, no se esperan efectos adversos para la salud basados en los cálculos de la dosis inhalada. Sin embargo, las personas con problemas respiratorios, como el asma, pueden correr un riesgo mayor. El olor derivado del tratamiento de tejidos con permetrina procede principalmente de los propelentes del aerosol y no del repelente de insectos en sí.

Se forma una fuerte unión entre la permetrina y la mayoría de los tejidos. De hecho, se observó cierta repelencia a los insectos en uniformes militares tras 50 lavados. Sin embargo, los uniformes se trataron utilizando un método de absorción en lugar del bote de aerosol. En los estudios realizados por el ejército de EE.UU., entre el 20 y el 30% del tratamiento con permetrina se eliminó tras el primer lavado. A partir de entonces, se perdía entre un 3 y un 5 por ciento en cada ciclo de diez lavados.

Los estudios en animales han demostrado que no se espera irritación o sensibilización de la piel tras la aplicación directa. En un estudio controlado en humanos, la permetrina no causó irritación cutánea significativa ni sensibilización cuando se probó en 200 sujetos. No se esperan efectos significativos en la piel por el uso de ropa tratada con permetrina.

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.
