Pick the pest and the location, optionally add severity. The tool ranks natural methods by documented effectiveness and flags methods that don’t work — drawn directly from the method pages on this site. Everything runs in your browser.

How the recommender decides

For each pest plus location combination:

  • Top priority methods are those with the strongest evidence and most direct effect for that specific situation. Sealing entry points appears as priority for most indoor pests because exclusion is the foundation of IPM. Eliminating standing water is priority for mosquitoes because it addresses the breeding cycle directly.
  • Supporting methods have evidence but are secondary or context-dependent. Essential oils, companion planting, and pheromone traps fall here for most situations — they add to a combined approach but rarely succeed alone.
  • Methods NOT recommended are explicitly listed when there is published evidence against effectiveness for that pest. Ultrasonic repellers for mice, bug zappers for mosquitoes, and decoy “fake nests” for wasps are examples — research has shown they do not work despite manufacturer claims.

The recommender does not invent confidence percentages or ranked numerical scores. It uses qualitative tiers because that’s what the underlying evidence actually supports.

What this tool does NOT do

  • It does not diagnose pests. Use the pest identifier for that.
  • It does not predict effectiveness. Outcomes depend on individual conditions, application skill, and local factors not captured here.
  • It does not replace professional consultation for heavy infestations, structural concerns (termites, carpenter ants in walls), or any bed bug suspicion.
  • It does not address every pest — only the nine common pests with full pages on this site.

Frequently Asked Questions

How does the recommender rank methods?

For each pest plus location combination, the tool returns methods ranked by documented effectiveness. Methods with strong evidence (physical exclusion for rodents, diatomaceous earth for crawling insects, eliminating standing water for mosquitoes) come first. Methods with mixed or weak evidence get lower scores. Methods with negative evidence (ultrasonic repellers for most pests) are explicitly listed as NOT recommended with the reason.

Why does the tool say some popular methods are not effective?

Several products marketed as natural pest control have been studied repeatedly and the evidence is largely negative. Ultrasonic repellers are the most prominent example — the FTC has taken enforcement action against manufacturers making unsupported claims. The tool surfaces this rather than hide it.

Does the tool recommend chemicals?

It recommends only natural and low-toxicity options. For severe infestations of certain pests (especially termites, bed bugs, and persistent rodent infestations) the tool will suggest professional consultation rather than recommending DIY chemical treatments.
