Arthropod Welfare in Pest Control

Billions of arthropods including cockroaches, ants, and spiders are killed daily with pesticides and traps, raising growing welfare questions.

Key Facts

Insects represent the largest group of animals by biomass on Earth
Evidence for insect nociception is growing but disputed
Sticky traps cause slow death over hours or days
Pesticides often cause paralysis and slow death rather than instant killing
Some arthropod species show behavioral responses consistent with pain avoidance

Welfare Considerations

If arthropods have any capacity for welfare-relevant experience, common pest control methods involving slow death by trap or pesticide represent significant suffering at enormous scale. Sticky traps cause prolonged immobilization with no possibility of escape. Even under significant uncertainty about arthropod sentience, the scale of potential suffering warrants consideration.

What You Can Do

Use more humane pest exclusion methods where possible
Choose instant-kill traps over sticky or slow-acting poisons
Apply the precautionary principle given uncertainty about arthropod sentience
Support arthropod welfare and sentience research
