Pesticide Types Explained: Pyrethroids, Neonicotinoids and Others in Plain Language

Pesticide names can be confusing. A basic grasp helps you ask better questions.

This is a simple overview, not a safety assessment of any product.

The short answer

Pest control products use different active ingredient groups. Pyrethroids are common insecticides in sprays; neonicotinoids act on insects' nervous systems and appear in some baits and gardens; insect growth regulators disrupt development; anticoagulants are used in rodent baits. Each has its own use and precautions. Read labels and ask your provider about products used.

Common groups

• Pyrethroids: widely used in household sprays.
• Neonicotinoids: used in some baits and garden products.
• Insect growth regulators: affect juvenile insects.
• Anticoagulant rodenticides: used in rodent baits.
• Boric acid and other minerals: used in some baits.

What matters

1. Use only as labelled.
2. Keep away from children and pets.
3. Protect water, bees and wildlife.
4. Ask your provider what is used.

A note

Safety depends on the product, dose and exposure. Ask your provider for the safety data sheet.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.
