German cockroach 100% Killer - The best in the market.Need to do some extra tricks (Read Below)
This product does work. I git rid if the entire population 99.9 in three weeks of regular use. The rest 1% am sure I will get rid of in the coming weeks.
Just simply spreading the power on floor or in corners may not work.
But I had to do a bit more from my side,rather than just simply dispersing or spreading the powder, I spread the powder in small "trays" (the lid of the food containers we get from restaurant) .
Then I prepared a "bait" . I took some left over food,cockroach's favorite food (a little fried rice, potato french fries, oily fried fish and sugar) and mixed it with the powder.
Then I placed a little bait in the mid of the each trays . Placing it mid made sure in order to eat they had to pass through the powder around it.
I placed the trays in potential locations (kitchen, bathrooms ,dining rooms) during the night. I made sure I did clean the area and floor before I placed the tray.
This will make sure the only available food is the one in the tray in those locations.
The bait(good oily food) and powder will easily attract the german cockroachs as the lights go down
Every night they came and ate the bait as well as powder. They passed through the powder and carried home the powder and food along with it.
Next few mornings I just harvested 100s dead cockroach from tray and around the floor. Every night I gave them fresh "bait" (basically oily food with sugar mixed with PF Harris powder) and placed it in mid of tray. They should be able to get into tray and get out easily. Make sure the tray is NOT having TALl smooth surface . Better is paper tray (make one if you can ) . A pizza box is a good one for this purpose.
Some may have went back to the nest and died. They took the powder and food carried along with them to nest.
I read and researched that
The female cockroach (are usually back in nest with egg) and with babies . They ate the powder on the body of these carrier cockroachs coming back and females and babies die.
Once they all start dieing and stop getting the food they start eating the dead ones ( poisoned and having the powder on their bodies) and the rest remaining aldo die.
It will be a chain reaction and the entire population is eliminated.
The point here is you need to let the cockroach go back to the nest after it visited your tray. They will die eventually and will carry the bait and powder back home yk kill the others. Never kill (intentionally) the contaminated carrier cockroachs,let them go back to nest.
It takes more than 72 hours to see a noticeable impact so don't get discouraged or disappointed. It takes time and very slow but effective and eliminates it from the roots.
It worked for me .I have reduced it to 99.9 % for sure in last three I zm going to continue this for next one month until I achieve 100% success.
