Pyrethrin products such as the Pyganic Pro concentrate or the 565 Plus XLO aerosol spray work very well to kill just about any insects that is sprayed directly. Pyrethrin products have no residual effect, so any insect that is not sprayed directly will not be killed. A good all around spray that works very well for roaches and spiders is Cy Kick CS. This spray can be used indoors and outdoors, has almost no odor, and is labeled for just about any insect that is likely to infest a house.
