Slug and snail control Copper has long been used by gardeners to deter slugs and snails, as they often avoid traveling over it. This is believed to be due to an electrical current or chemical reaction they experience through their slime. Slug copper tape can be an effective tool in your slug and snail deterrent arsenal. Use our copper slug repellent tape to protect your garden by lining your pots and raised beds. Copper tape is an eco-friendly alternative to potentially harmful poisons and chemicals, the perfect control for pets and children. This also makes it an ideal indoor repellent. EMI and RFI shielding Eliminates electromagnetic and radio frequency interference. In our increasingly electric world, electromagnetic interference (EMI) and radio frequency interference (RFI) are always present. Common examples include electric guitars "whining" or speaker distortion. Copper acts as an effective EMI/RFI shield due to its effective attenuation of electromagnetic waves. For this reason, copper is used as EMI shielding in hospital MRI machines and everyday consumer electronics. Electrical use and repair Did you know that copper has the highest electrical conductivity of non-precious metals? Copper is an extremely conductive material. Use copper tape for electrical repairs, wiring, and even for educational "paper circuits". Stained glass Use copper tape to create beautiful stained glass artwork. Copper tape is used in modern stained glass techniques: the copper strip acts as a surface on which solder can bond.
