Q&A Home

Tammie from Lorain Ohio writes,

Will Demon wp kill roaches and their eggs


Demon WP will kill roaches but it will not kill roach eggs. Insecticides will only kill insects after they have hatched from the eggs. Insecticides cannot penetrate the egg shells. We would recommend using an Insect Growth Regulator such as Gentrol IGR along with the Demon WP as it can make some of the eggs non-viable and it will halt the reproduction of the juvenile roaches.
