Repels: Japanese beetles , Spider mites , Harlequin bugs , Root-knot nematodes , Ticks , Silver fish & Bed bugs
A special chemical in the chrysanthemums, called pyrethrum, is the thing that keeps bugs away. Roaches, ticks, fleas, bed bugs, spider mites, Japanese beetles and ants – be gone. The ingredient is part of different insecticides in the USA and is used in sprays and flea pet shampoos. Be careful with the spray bottles, if you happen to have one, since pyrethrum is poisonous to people in certain amounts.
