Firstly, the cute designs makes the disgusting nature of this just a little more bearable. As you can see by the pictures they are indeed sticky enough. They also arrived on time.
The thing about gnats is you don't realise how big of an infestation you have because you only notice a few flying/crawling at a time. This was my first time having an infestation and I had no clue which plant or compost bag was the initial problem but they spread like wildfire.
These traps let you know how bad it is. They are very effective at attracting and catching the adults, however they do not kill the eggs or larvae. So another solution is needed to kill the larvae in the soil in EVERY PLANT (I use two methods, either a Neem Oil drench or repot using sterilised potting medium). However, if there are any adults still flying around the cycle will continue. The key is getting rid of most or all the adults and killing off the eggs/larvae around the same time.
The first two pics show how the pads arrive and what they look like. The third picture is just hours after placing them in the pots. The video and last picture is about a week after the traps.
They are certainly not a beauty to look at nor are they a single solution for gnats but THEY WORK!
