Also ... late summer is roach time, especially after all the rain, the disturbances of the walls and traffic of the remodeling.

Check to make sure all pipes are sealed with flexible caulk where they come through the walls or floors. If there is a gap, puff some Roachpruf inside the wall, then seal it.

Use something (I use a large syringe with a plastic tube on it) to puff boric acid (Roach pruf) behind and under cabinets, and under all drawer stacks. Behind and under all appliances, and especially under stove and refrigerator.

No need to call a pro..mix boric acid, flour and sugar in equal proportions...put it where roaches may go. They will soon be gone.

You don't even need to mix it with anything. Cockroaches are neatfreaks and groom themselves constantly. If they walk through it, it'll end up in their bellies. Other less fastidious insects might need to have it spiked with something tasty, but if you're going to be putting it behind your walls and under your floorboards, you might want to keep it pure.

What do you mean you mix all that equally but do you put it in a bowl how does it is it just a spot I don't know how do you put it around your house
