Humble1,
Thanks for backing me up!
I use "Demand" CS--Lambda Cyhalothrin 9.7% in the encapsulated suspension from Zeneca.
I bought this from my exterminator years ago, and this little 8 oz. bottle has done wonders.
Luv2Fly,
Keep in mind you can buy the Lambda Cyhalothrin in stores but it is in lesser strength formulations and it isnt the CS formulation. Which ever, read that label!!!!!! I don't use it on or near the countertops, because of the empacsulated product. I don't trust anything that leaves a residue on my food surfaces. The encapsulated products dry on the surface and leave behind a little bubble of chemical if you want to call it that!!!!!!
This product I purchased, is or at the time, was only purchasable by licensed operator's in structural pest control. Don't be misled by the other brands.
Permethrin will flush the roaches out of the hiding places and then band them with the Bifenethrin. Keep this fact, some of these chems will stain walls--baseboards--drapes, so read the label for more adequate educating. I don't have the current label on my bottle, so without googleing, I can't give you any more info.
Good Luck!
