Pet-Safe Pest Control: What to Avoid Indoors

Keep your cats and dogs safe while treating your plants. A guide to non-toxic pest control.

Key Takeaways

  • Check soil moisture before watering.
  • Look for signs of stress early.
  • Consistency is key for recovery.

Many common systemic pesticides are toxic to pets if ingested.

DANGER: Systemic Granules (Imidacloprid)

Highly effective against pests, but toxic to cats and dogs. The plant absorbs the poison, so even munching a leaf can be dangerous. Alternative: Beneficial nematodes or predatory mites.

CAUTION: Neem Oil

Generally considered safe, but can cause stomach upset if licked in large quantities. Tip: Keep treated plants in a locked room until dry.

SAFE: Insecticidal Soaps (Potassium Salts of Fatty Acids)

Usually safe once dry. Always check the label for “Safe for use around pets”.

SAFE: Diatomaceous Earth (DE)

Mechanical killer (microscopic shards). Note: Do not inhale the dust. Use “Food Grade” DE.
