Ortho Home Defense Insect Killer for Cracks & Crevices is a versatile spray foam designed to target hard-to-reach areas where roaches and other insects often hide. One of its strengths is its long-lasting effect, which can kill German and American cockroaches for up to 18 months and carpenter ants for up to 1 month on non-porous surfaces. This makes it highly effective for prolonged protection both indoors and outdoors.

The foam application method is particularly beneficial as it expands to cover hidden spaces, ensuring thorough coverage compared to traditional sprays. Additionally, the product is non-staining, making it safe for use on surfaces that water wouldn't stain.
