## Description

Gardner&apos;s Insect Monitor Cards are designed to capture all types of insects that harbor in and around plants. Fungus gnats, white flies, aphids, thrips, and leafminers are just a few of the species attracted to our traps.

In order to maximize catch rates of the different species of insects we utilize two insect attracting colors on each trap: Brilliant Blue and Yellow. Traps are packaged as 10 double-sided cards per pack.

Non-Toxic
No Mess
Easy to Use
1&quot; Monitor Grid for Easy Insect Identification
We have perforated the traps to increase the use options:

Use as a 4&quot; x 8&quot; trap.
Fold into triangle-shaped delta.
Tear apart at perforations for use in smaller areas or close to base of plants.
How to use:

Fold or tear trap into the desired format.
Peel protective cover from one or both sides of the trap.
Place or hang traps close to plants. When used in large areas, 
traps should be placed 10-15 feet apart.  For both indoor and outdoor use.
Monitor traps on a regular basis - replace as needed.

    Best Sticky Traps I Have Ever Used!
  

*by A***R on Reviewed in the United States on March 27, 2012*

These work! I had a fungus gnat infestation from starting seeds and tried reducing watering frequency, insecticidal soap and neem oil. None helped and the fungus gnats got worse and worse. Finally decided to try these and could not be happier with the results. The traps are quite large (compared to others I have tried) and really a good deal. The gnats get stuck to both the yellow and blue sides. I could not believe how many were stuck to it in just 1 day. The gnat population has been drastically reduced now. Get these ones! They work!

    great product
  

*by T***C on Reviewed in the United States on August 4, 2013*

this sticky card will trap every insect that is unfortunate enough to land on it.. there were 100s of  wasps , flies , white flies , fungus gnats and various other undesirables on each one after only a week..  these sticky cards are impervious to water as well.. excellent  organic way to control garden pests..  I have tried a few other sticky products but this is the best by far.. its a bit messy to handle , which you inevitably will have to do , so  have some vegetable oil readably available to get it off of your fingers and hands  as nothing else will work..  don't worry , its non toxic..

    Nice n' sticky, but only good for monitoring; read review for the true fix
  

*by H***4 on Reviewed in the United States on August 20, 2017*

these are great monitoring cards, again MONITORING cards.  These will NOT fix your fungus gnat problem, they will only alert you to their presence and help to reduce their nuisance of flying around.  I have been battling houseplant fungus gnats for quite some time.  I have tried just about everything, and I believe that I have ultimately found the fix.  Day one, spray Bifenthrin on the soil surface to saturate.  Day two spray imidacloprid on the soil surface.  Day 3 spray Onslaught FastCap on the soil surface, and then cover the soil surface with about 3/4 - 1" of Quikrete play sand.  Then if you have it, spray neem oil on the sand surface to saturate the sand.  Place your monitor cards out several days after doing all this.  You should not see one gnat!  This method might not work very well for those of you with toddlers, or very young children that might play with the sand in the pots with all the pesticides.I know the process is somewhat a pain in the butt, but if you are serious about getting rid of your fungus gnat problem this is what I have found.  I also have about 1 gallon of hydrogen peroxide 3% to mix with water in a 1:4 ratio to nuke the eggs and larva for upcoming waterings should I see a reemergence of the gnats.I use quite a bit of peat moss and vermiculite in my growing mix so that I don't have to water but once a month on my house plants, but because of the high retention of this water, these gnats love it!
