What will kill roaches but not harm pets?

Diatomaceous earth is an effective and pet-safe option for killing roaches. This natural powder damages the exoskeletons of insects, leading to dehydration and death without posing a risk to pets. Additionally, using essential oils like peppermint or tea tree oil can repel roaches without harming your furry friends, though they may not be as effective for severe infestations. Always ensure to keep any pest control treatments out of reach of pets for their safety.
