Thrips (order Thysanoptera) are minute, slender insects with fringed wings. Other common names for thrips include thunderflies, thunderbugs, storm flies, thunderblights, storm bugs, corn flies and corn lice. Thrips species feed on a large variety of plants and animals by puncturing them and sucking up the contents. A large number of thrips species are considered pests, because they feed on plants with commercial value. Some species of thrips feed on other insects or mites and are considered beneficial, while some feed on fungal spores or pollen. Approximately 6,000 species have been described. Thrips are generally tiny (1 mm long or less) and are not good flyers, although they can be carried long distances by the wind. In the right conditions, like indoor grow rooms or greenhouses, many species can exponentially increase in population size and form large swarms because of a lack of natural predators, making them an irritation to humans.
A thrip infestation can be prevented simply by making sure that you do not let them into your garden, thrips and most garden pests are most likely to hitch a ride directly into your garden on clones, garden equipment and on your own clothes and shoes.
If you do notice thrips on your plants don’t panic, they wont kill your garden, but a larger infestation can lower yield and leave droppings in your flowers which is a no go. If you have any intakes make sure they have a filter of some sort to prevent insects and even mold from getting into your environment.
