After hatching, the nymphs go through a series of stages, the final being pupation. Thrips mature very rapidly. The transformation from egg to adult can take place in as little as 11 days with three weeks as a general maximum. Thrips are not generally fussy eaters feeding on a wide variety of plants as well as palm trees. The first step in controlling thrips is finding them.
Detection can be a challenge given the small size of the insect.
Some sources suggest shaking suspect leaves or flowers onto white pieces of paper and then examining them with a magnifying glass. Sticky traps are also available for this purpose. Once detected, insecticides can be an effective way of controlling thrips. Consult your local tree care or landscape specialist for advice. As always in the use of insecticides, remember to follow directions carefully.
