I need a quick/instant knock down spray for german roaches.
I have a pretty bad German roach problem. Which chemical has a quicker knock down for German roaches? Esfenvalerate or Cyfluthrin? I plan on alternating 2 or 3 different chemicals over the next year to get rid of them but I would like at least one chemical I purchase to be able to kill them quickly in case I run into any nests I am able to spray. I also plan to mix these chemicals with Pyridine when I use them and supplement with roach baits which I will also alternate throughout the year. I have one more question. Which aerosol spray do you recommend for instant knock down of German roaches?
We would recommend using Cy-Kick Aerosol. It will provide a quick knockdown as well as a residual. Apply as crack and crevice or void treatment where insects may be harboring. These may include openings around pipes and sinks, under refrigerators, behind baseboards, washing machines, stoves, cabinets, sewers, floor drains, and meter boxes. Spot treatment may also be made to areas including closets, around water pipes, doors and windows, around refrigerators, cabinets, sinks, stoves and other equipment, shelves, drawers and similar areas.
We would also recommend using Maxforce FC Magnum. You will need to put this in areas that cannot be sprayed so that the gel does not get contaminated. Roaches will be less likely to eat it if it is contaminated.
We would also recommend using Gentrol Point Source as well. This is an IGR (insect growth regulator). It is a birth control for the roaches and will stop them from reproducing.
As an extra preventative, using dust within the walls will dry them out if they are there. Delta Dust Insecticide is a waterproof dust that lasts for at least eight months. It should be applied with a hand duster.
