Will Cockroaches Eat Catnip?

Cockroaches will not eat catnip, which is why it can be used as a nontoxic repellent against insects. Iowa State University researchers found that nepetalactone, the chemical in catnip that attracts cats, effectively repels cockroaches. In fact, nepetalactone from catnip was found to repel cockroaches 100 times better than DEET, the common commercial repellent for cockroaches, mosquitoes, and other insects.

Although scientists don't know exactly why cockroaches are repelled by the nepetalactone in catnip, this discovery could have a positive impact on pest control. Nepetalactone could be used to prevent infestations from reoccurring after an extermination, or it could serve as a preventative measure to reduce the need for more toxic chemicals.

More about cockroaches:

• Cockroaches are social creatures that prefer to eat while in a group, even when they could have a food source all to themselves.
• The name “cockroach” comes from cucaracha, the Spanish word for “crazy bug” -- a reference to the zigzagging motion the insects make when they run.
• Because they possess sensory organs known as palpi, cockroaches can taste without actually eating, which can allow them to avoid poisonous chemicals.

Frequently Asked Questions

Can cockroaches be repelled by catnip?

Yes, cockroaches can be repelled by catnip. Studies have shown that catnip contains nepetalactone, a compound that is a natural deterrent for cockroaches. According to research by Iowa State University, catnip is more effective at repelling cockroaches than DEET, a common ingredient in insect repellents.

Will cockroaches eat catnip if they come across it?

Cockroaches are unlikely to eat catnip because they are repelled by the essential oils it contains. While cockroaches are omnivorous and not particularly picky eaters, the nepetalactone in catnip is a natural insect repellent that makes it an unattractive food source for them.

Is catnip a reliable method for keeping cockroaches away?

Catnip can be a part of a pest control strategy, but it should not be relied upon as the sole method for keeping cockroaches away. It is most effective when used in conjunction with other pest management practices, such as maintaining cleanliness and sealing entry points in your home.

How does catnip compare to other natural cockroach repellents?

Catnip is considered one of the more effective natural cockroach repellents due to its active compound, nepetalactone. It is comparable to other natural repellents like bay leaves, cucumber slices, and garlic, but its efficacy is particularly notable. However, its effectiveness can vary based on environmental factors and cockroach species.

Can catnip be harmful to pets or humans?

Catnip is generally safe for both pets and humans. In fact, it is well-known for its stimulating effect on cats, which is usually harmless and temporary. However, consuming large quantities of catnip may cause mild stomach upset in some animals. For humans, catnip is often used in herbal teas and is considered safe.

How should catnip be used to repel cockroaches?

To use catnip as a cockroach repellent, place small sachets of dried catnip leaves in areas where cockroaches are likely to enter or hide, such as near baseboards, under sinks, and in cupboards. Alternatively, a catnip tea can be made and sprayed around these areas for a similar repellent effect.
