A commercial source of pyrethrin used for insecticides. The flowers are dried, then pulverized to a powder and mixed with water and a little alcohol for insecticidal spray. Used against aphids, pickleworms, leaf hoppers, spider mites, harlequin bugs, cabbage worms, and ticks.

An insecticidal spray can be made using your own flowers. Two recipes follow.

1. Steep 4 oz. of pyrethrum powder in 2/3 C. denatured alcohol. Dilute with 13 gallons of water to spray.

2. Mix 1 Tbsp freshly ground dried flowers with 2 quarts of hot water; add a little soft soap (should not contain degreasers; use something like Ivory dishliquid); add 2 Tbsp vodka (or denatured alcohol which is better); let stand 20 minutes and spray.
