To stop the damage that this pesky insect can cause, it is worth taking a look at these Yellow Sticky Traps from Trapro. These have been intelligently designed to attract specific insects, including Thrips, Fungus Gnats, Leaf Miners and Aphids as yellow is a color they are drawn to. Simply attach them to a stick and place it either in the pot you are growing your cannabis in or in the ground next to your plants.
This product is eco-friendly, suitable for indoor and outdoor use and is a cheap means of controlling pests. The only downsides of these Sticky Traps is that you will need to replace them regularly due how quickly they fill up with pests!
