This invention relates to insect control with Camptotheca products, particularly, termiticides, baits, preservatives, and termite-resistant products. Natural or synthetic Camptothecin and/or one of its natural or synthetic analogs is applied to deter and/or eliminate termites, while flavonoids are applied to attract termites. CPTs and/or CPTs-containing plant matter is processed with cellulose products to produce termite-resistant products and structures.
