Dr. Rechell's anti mosquito bracelet repels mosquito's for up to three weeks.
Active ingredients : geraniol, peppermint oil
You only need to wear the bracelet when it is needed before going to a zone where there could be mosquitoes.
The bracelet is inside a double envelope, thick blister package. It is a very high quality package. It is the only way to preserve the active inside the bracelets as the actives are very volatile and it is the only way to ensure the 3 year tested shelf life. It is one of the key point that differentiates the product and makes it an ideal addition to your seasonal outdoor supplies.
Once you open the package, the bracelet will be active around 3 weeks depending on weather conditions (Temperature and degree of humidity). If you want to extend the duration of the bracelet after opening the packaging, the best would be to put it tight into aluminum foil. Another option would be to use a Ziplock or aluminum foil. Aluminum foil is more effective to prevent loss of active.
