The effectiveness of Repelz tag in preventing flea and tick "infestations" is 100%, and in general, the Repelz tags have 95% effectiveness. The only condition in which the Repelz Tags demonstrate lower effectiveness is when the animal has a weakened immune system that prevents the tag from synchronizing with the heart's electromagnetic field. All purchases on Repelz Tag are backed by our 100% money-back guarantee, so you can try it risk-free and see the results for yourself.

After the tag is activated, fleas or ticks are not expected to voluntarily crawl/jump onto the animal; however, if you're finding fleas or ticks on your pet you may consider the following possibilities:

• The precondition to ensure a clean pet (i.e. no existing eggs/larvae/fleas/ticks) was not met. If this is the case, please strictly follow the instructions to meet this precondition.
• The presence of eggs/larvae of fleas/ticks that were dormant for weeks on the pet or in their environment, and have become active since.
• Forced physical contact such as rolling on a flea/tick-infested ground/grass, playing with other infested dogs, or ticks falling from branches. In such cases, the adult fleas/ticks are expected to leave the pet's body within 48 hours. In some cases, by the time the current fleas/ticks leave the body, the pet may pick up more new ones on a regular basis, creating the false impression that the tag is not effective. If this is the case, minimizing exposure to flea/tick-infested areas will help address the issue.
• The only condition in which the Repelz Tags demonstrate lower effectiveness is when the pet has a severely compromised immune system that prevents the tag from synchronizing with its heart's electromagnetic field.
• In less than 1% of the cases reported by customers, we have not been able to determine conclusively the reason for the tag seeming to have reduced efficacy on the pet. Factors such as interference from other devices may have a role; however, we have not seen any direct evidence of such interference. To account for such unknowns, and to ensure 100% customer satisfaction, we offer a 90-day money-back guarantee.

We do not do any custom engraving on the Repelz tag at this time, but this option will be available from one of our partners in 2023. A separate metal name tag may be added, instead, to your pet’s collar, along with the Repelz tag.

Yes. Continue to treat your pet with worm treatments for all worms including heart worm and tape worm. Worms are internal parasites and can enter your pet’s body through their digestive system and are therefore not preventable with any external treatments.

The Repelz tag was only tested on dogs and cats against ticks and fleas. It is a product intended for and approved for pets only. There is anecdotal evidence that it repels other parasites as well, however, we do not offer this guarantee.

No, there are no chemicals on the Repelz tag. It is completely safe to touch. We do advise a thorough delousing of your pet at the time the Repelz tag is attached and that the final chemical treatment is applied at the same times as the tag to provide protection while the Repelz tag is activated by your pet’s circulatory system and the magnetic shield is established.

The Repelz tag has the very beneficial effect of improving circulation which may be seen in the form of increased energy, reduced fatigue, and better immune response. The Repelz tag is safe and beneficial for use on all cats and dogs from the day of their birth, during pregnancy, during convalescence, and in the end stages of life. Repelz tags have absolutely no contraindications or negative side effects.

No. The Repelz tag should remain on your pet while bathing, swimming, and even during veterinary X-Rays. Removing the Repelz tag from your pet’s body will remove the protective shield from its body. We advise loosening the collar during washing. If the Repelz tag is removed from your pet’s body, it will need to go through the activation period again.

We recommend a single Repelz tag for 100 kg or 220 lbs. In the case where weight exceeds these limits, and for large dogs with thick, dense, and long fur, you may consider using an additional tag.
