Be clean , keep rooms clean. Perimiter spray your property with very harsh chemcials.
Use employ enthropogenic fungi and bacteria as clean ups/control, botanicals and oils as preventatives and rotate MoA when using different products for control.
for example... dont use an ingestible poison before you use a contact killer use it after when their populations spike from the the contact kill, use botanicals and neems inbetween ..and so forth understanding the interaction of your products with their target pest.
normally erradication will come with control of reproduction, feeding, bug growth or life stages and then finding a product that affects all lifestages is always a great clean up to a mixed MoA program.
