Final Thoughts

Depending on the termite situation and area of treatment, a type of termite treatment method may be more ideal than the other. For house perimeter treatment and protection, insecticide and granular termite killers are great options as they are easy to apply and can cover a wide area relatively quickly. 

For spot treatment or treating areas with narrow openings, the foam termite killer will make an ideal option as the foam termiticide is able to easily reach into these small areas and quickly expand to cover the internal area, killing all termites or other pests on contact.
