Demon Max, manufactured by Syngenta, is a multi-use Cypermethrin-based emulsifiable concentrate used to control termites and other wood-destroying insects, crawling insects, and flying insects found outside or inside various building structures.
This product can be used for pre-and post-construction termite treatments and spot, crack and crevice, perimeter, and broadcast treatments.
Demon Max has a residual effect lasting up to 90 days, making it great for barrier applications to prevent insects from finding their way indoors. It also delivers a quick knockdown to kill insects already invading indoor areas.
Tools Needed
A backpack sprayer, handheld pump sprayer, hose-end sprayer, or skid sprayer is needed to apply as a general insecticide.
The handheld pump sprayer is suggested for indoor crack and crevice applications, and the hose-end sprayer for broadcast applications.
How to Use
- Step 1: Determine how much Demon Max Insecticide to use by measuring the square footage of the treatment area. To find the square footage, measure the length and width of the treatment area in feet, then multiply them together (length X width = square footage). For most pest control applications, the rate is 0.5 to 1 fl. oz. of Demon Max Insecticide in a gallon of water to treat 1,000 sq. ft. Refer to the label for specific application rates and restrictions.
- Step 2: To mix using a hand pump sprayer, fill your sprayer halfway with water. Add the proper amount of Demon Max to the spray tank, and then fill your sprayer with water. Screw the sprayer's lid on tight, and shake your sprayer to mix well.
- Step 3: Apply Demon Max outdoors around your yard and ornamentals where you have seen pest activity. Use a fan spray setting with low pressure for broadcast and spot spraying for uniform coverage. Spot spray outdoors around the structure, focusing on entry points around windows, doors, and under eaves. Indoors, you can use Demon Max as a spot or crack and crevice treatment under sinks, cabinets, appliances, baseboards, and similar areas.
Where to Use
Demon Max Insecticide can be used indoors and outdoors in residential and commercial areas. It can be applied in wall voids, window sills, and baseboards as a cracks and crevice treatment. It can be used as a perimeter spray around doorways, windows, and foundations or as a broadcast spray on lawns and flowerbeds. It is also ideal for trenching subterranean termites. Demon Max is not approved for use in food areas where food is prepared, served, or stored.
When to Use
This product should be used when you have a pest infestation indoors or outdoors in your yard. For outdoor applications, apply during calm days when rain is not in the immediate forecast.
Safety Information
Demon Max Insecticide is safe for children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing or applying this product.
Sprayed surfaces should be avoided until the spray has dried completely.
Special Considerations
Demon Max is an emulsifiable concentrate, and as such, it is important to know that this type of formulation does not perform well on porous surfaces like brick or raw wood as it will absorb into the material and not stay on the surface. Also, when using Demon Max for subterranean termite control, the product is to be used by individuals/firms licensed or registered by the state to apply termiticide products.
