Short Review of Demon WP

Demon WP Insecticide is a water-soluble powder formulation, providing both fast-acting and lasting residual control of over 30 types of pests. From cockroaches and ants to spiders and wasps, Demon WP has made a name for itself due to its efficacy and broad-spectrum control.

Key Ingredients
The primary active ingredient in Demon WP is Cypermethrin, a synthetic pyrethroid. It acts by targeting the nervous systems of insects, disrupting their normal function and eventually leading to their death. Understanding this is crucial, as its mode of action helps determine its efficacy and possible side effects.

Mode of Application
Being a water-soluble powder, Demon WP is typically mixed with water and applied using sprayers. It forms a milky solution, which, when dried, forms a protective barrier, ensuring that any insect coming into contact with it gets exposed to the active ingredient.


  • Broad-spectrum Control: Demon WP is effective against various pests, making it versatile for indoor and outdoor use.
  • Residual Effect: Once applied, its effect can last for weeks, ensuring long-term protection against re-infestations.
  • Economical: A single envelope can be mixed to create several gallons of solution, offering cost-effective pest control.
  • Low Odor: Demon WP has a low odor profile unlike some insecticides that can leave a strong chemical smell.



  • Safety: As with all pesticides, proper precautions should be taken during its application. It’s essential to keep it away from children and pets and ensure good indoor ventilation.
  • Environmental Impact: Cypermethrin can be toxic to aquatic life. Hence, avoiding runoff that might reach water sources is crucial.
  • Possible Resistance: Over-reliance on any single mode of action can lead to pest resistance. Rotating with other pesticides or using an integrated pest management approach can be beneficial.

What Pests Does it Target?

Demon WP has a broad spectrum of target pests, which include:

  • Ants
  • Cockroaches
  • Spiders
  • Crickets
  • Earwigs
  • Wasps
  • Bees
  • Fleas
  • Mosquitoes
  • Termites (above ground only)

This makes it an all-in-one solution for most common insect-related problems that one could face in various settings.

Easy Application
One of the standout features of Demon WP is its ease of application. You can opt for a 0.1% concentration solution by mixing one packet with a gallon of water or go for a 0.2% concentration by using two packets. Several instructional videos are available for a detailed understanding of how to mix Demon WP.

Feedback & Testimonials
Numerous users have cited Demon WP’s quick knockdown effect and its lasting residual action as significant benefits. However, some users have mentioned the need for reapplication in areas with heavy infestations or in regions with frequent rains.

Demon WP Insecticide offers a promising solution for those plagued by a myriad of pests. Its broad-spectrum control, residual effect, and economic benefits make it a worthy consideration. However, like all pesticides, it’s crucial to apply them responsibly, bearing in mind its potential impacts and the safety of those around them.

If you’re considering integrating Demon WP into your pest control strategy, it’s always advisable to consult with a professional or thoroughly read the product label. Remember, the key to effective pest control is not just the product but also its judicious and informed application.
