How well does Cyper TC work for ants?

I am wondering how effective this product is at controlling red ants, crazy ants, sugar ants, etc. Does it leave a residual to continue to kill them for months at a time? How far out do I need to spray around my house? Also most importantly what is the mixture rate for 10 gal tank? The pest man came to my house to use this stuff and on the ticket he used 8 oz for a 50 gal tank, is that safe is that 25.3% cyper tc or is it weaker?


Cyper TC is labeled for ant around the outside perimter of a structure and it will kill ants that come into direct contact with the treated surface. Cyper TC will not kill the ants that are back at the nest (For this type of effect we recommend Termidor SC). According to the Cyper TC product label:

BARRIER TREATMENT: Apply 0.1% (5.1 oz product per gallon of water) to a band of soil and vegetation 6 to 10 feet wide around and adjacent to the structure. Also, treat the foundation of the structure to a height of 2 to 3 feet. Use a treatment volume of 2 to 10 gallons per 1,000 square feet. Higher volumes of water may be needed if mulch or leaf litter is present or dense foliage exists. House siding may be treated if boxelder bugs, elm leaf beetles, earwigs, silverfish or other similar pests are present.
