Skin Lightening Treatments. Skin lightening products -- also known as bleaching creams, whiteners, skin brighteners, or fade -- work by reducing a pigment called melanin in the skin. Most people who use lighteners do so to treat skin problems such as freckles, age spots, acne scars, or discoloration related to hormones.he active ingredient in some skin lighteners is mercury, so bleaching can lead to mercury poisoning. Mercury is a toxic agent that can cause serious psychiatric, neurological, and kidney problems.
Spider mites - outdoors. Spider mites are very common pests of outdoor plants. The mites suck juices from the plants, causing the plants to look dull and unhealthy. Mites also cause plants to lose vigor so that they may be unable to overcome a severe infestation, resulting in the plant's death. In Missouri, the most common outdoor spider mite is the two-spotted spider mite.
Broad mites commonly infest African violet, ageratum, azalea, begonia, dahlia, larkspur, gerbera, gloxinia, ivy, jasmine, impatiens, lantana, marigold, mum, petunia, snapdragon, verbena, and zinnia. Cyclamen mites are found on many of the same plants, as well as on strawberry. The saliva of cyclamen and broad mites is toxic to plants and causes twisting, curling, hardening and distortion of growing points. Infested plants typically appear distorted, have crippled crowns, and have premature bud and flower death.
