What To Look For
Some varieties of thrips will cause a more general type of plant injury to occur, including drooping or wilting leaves, but many types will leave telltale signs of the damage they have done. Be aware of these signs and keep an eye out for them on your home or garden plants. This is an important step in confirming that the damage you have sighted is caused by thrips.

How Can I Confirm I Have Thrips?
Due to their small size, a handheld magnifying glass can come in handy to confirm the presence of thrips if you suspect that they may be the cause of visible plant damage. We have provided several recommended ways to find a sample insect to identify below.
- Set out blue or yellow insect test cards or glue boards around suspected breeding grounds to trap nearby thrips.
- Hold a sheet of white paper under an affected plant and knock or shake the stalk. If thrips are present they will fall onto the paper where you can see them clearly.
