If ants, termites, roaches, spiders, or other pests overrun your home or property, you certainly want the best insect treatment possible. Researching insecticide treatments can seem confusing and overwhelming for non-professionals. This article aims to simplify your insecticide options. Demon Max Insecticide and Demon WP Insecticide present two of the most trusted and effective options on the market for eliminating a wide variety of bugs.

What is the Difference Between Demon WP and Max?

Although the same company makes Demon WP Insecticide and Demon Max Insecticide, these products are formulated and marketed slightly differently. Most notably, Demon WP comes as a wettable powder, but Demon Max is a liquid concentrate. Both products are intended to be mixed and diluted with water, giving the consumer a range of choice concentrations. 

Each Demon WP package contains a foil envelope that houses four product packets. Each foil envelope, or four boxes, will make 2 to 4 gallons of the diluted insecticide mixture. On the other hand, Demon Max comes in a pint-size container. Because you can mix 1.3 to 5.1 ounces of Demon Max for every gallon of water, this pint-size results in around 3 to 12 gallons of the final diluted mixture. 

Additionally, both Demon Insecticides have very similar purposes. Although Demon Max is advertised mainly to kill termites, it kills all the same bugs as Demon WP. Both products are formulated with the same active ingredient, cypermethrin.

Demon WP contains a 40% concentration of cypermethrin, but Demon Max includes a 25.3% concentration. However, the attention of the final mixture made with either product depends on how much water you mix with the products.

How Demon Insecticide Works

Demon Max Insecticide and Demon WP Insecticide rely on cypermethrin’s active ingredient to kill many bugs. Cypermethrin is a synthetic pyrethroid used in many typical insecticides. It works by quickly affecting an insect’s central nervous system after ingestion or contact. The insect becomes paralyzed, preventing it from obtaining food or carrying out other necessary functions.

Cypermethrin causes a relatively quick death for insects, although it does not work immediately. Cypermethrin may take a few hours, or even a day or two, to kill insects entirely. However, in terms of insecticides, the results shown by cypermethrin are proven effective, fast, and long-lasting.

How To Use Demon Mx and Demon WP Insecticide?

  • Both of these products should be diluted in water before being sprayed. You can use 1 to 2 packets of Demon WP per gallon of water. Additionally, dilute 1.3 to 5.1 ounces of Demon Max per gallon of water. If you are dealing with a large number of insects or more giant insects (such as cockroaches or scorpions), you may want to use the higher concentration options.
  • However, if you’re going to get rid of a small number of insects or want to spray for maintenance, you should only need one packet of Demon WP or a low concentration of Demon Max. 
  • Demon WP and Demon Max should be poured into a sprayer, such as CHAPIN 20002, available on Amazon, containing your desired amount of water and then lightly shaken.
  • Make sure to evenly distribute the product within the water to achieve the best results.  Demon WP and Demon Max are primarily intended to be used outdoors, but these products can also be used as a spot, crack, and crevice treatment inside.
  • Ensure the product fully dries before allowing the use of that area again. Additionally, you can wear personal protective equipment (PPE) while applying (such as long sleeves, glasses, or a mask). 
  • Both of these products contain detailed instructions that will help you learn how to apply them. Additionally, taking special precautions in certain areas, such as inside or around a pool, would be best.

What to Expect

As mentioned before, the results of Demon Insecticides are not instantaneous, but they’re relatively immediate in insecticide treatments. All the insects inside your garage or on your porch won’t die within minutes but within hours or a day. One of the best features of Demon Insecticide is the residual power it contains. This means that Demon Insecticide will keep working weeks and even months after you first apply it.

Demon WP and Demon Insecticide have residual power for three months. However, you can reapply as often as each week if needed.
