WHAT CAN WE USE IN THE OFFICE THAT IS NATURAL TO CONTROL GNATS? WE HAVE THEM IN SOME POTTED PLANTS AND THERE ARE A LOT OF PEOPLE WORKING SO IT HAS TO BE SAFE.
There are two organic products that work well for gnat control in an confined area like an office. The simplest thing you can do is set out the BUGSTICKS GLUE TRAPS These are commonly used for aphids and whiteflies but they work for gnats, fungus flies and other potted plant pests too. This would be your safest choice. The following video shows what they look like and how to set them up.
If you prefer to spray, get the ORGANIC HOUSE PLANT SPRAY. This non toxic aerosol is effective on many insects and can be safely used inside around people and pets.
