Early Warning Devices
Yellow Sticky Trap - By setting yellow sticky traps out in the landscape early in the spring, near the plants normally attacked by thrips, you will be able to catch the first thrips of the season and thus learn of their arrival. Now you can take effective preventive action.
Controlling Thrips With No Insecticides
Aluminum Mulch
If you can stand them around your landscape plants, aluminum foil and aluminum polyethylene mulches reduce the number of thrips.
Diatomaceous Earth
Sprinkle diatomaceous earth around very small trees to create a barrier for the pest. You can also dust the whole plants, beginning from the ground and working upward. Use diatomaceous earth in the late evening or at night to minimize injury to predator insects.
Organic Mulch
Spreading 4 to 6 inches of heavy organic mulch beneath plants keeps adult thrips from emerging in early spring. It may also prevent thrips that pupate in the soil from finding suitable pupation sites later in the season.
Mist Plants
Thrips prefer a dry environment, so make sure plants are adequately misted and watered.
Massaging Flowers
Try squeezing infested flowers carefully between your thumb and forefinger to kill thrips that have settled in between the petals.
Controlling Thrips With Insecticides
Using Natural Insect Repellents
There are several natural insect repellents that often kill thrips on contact, but then will create a bad taste for the critter and make it go someplace else to munch. Neem Oil Soap, Hot Pepper Wax, and Garlic Barrier all have this potential repellent capability when applied properly on the tops and the bottoms of leaves of the target plant. The repelling effect will last for several weeks to a month depending on the weather conditions. See the Natural Repellents in Yardener's Tool Shed.
