i use liquid dish soap & cayenne pepper, & rubbing alcohol in water for a spray. diaomaceos earth & rotonone dust work also for most all insects. wear a dust mask when you apply it. i would also fill a spray bottle with water & rinse off the flower blossoms. bees love the blooms of cucumbers, melons, & squash. you can but ladybugs. they eat aphids & insect eggs. i also watch the leaves for insect egg clusters & clip those leaves.
