Good afternoon,We have acquired a number of indoor plants in our office and now seem to have these black gnat like bugs as a result. They are quite annoying to say the least. If you have any advice on how to eliminate them our office would be very grateful. Thank you in advance.
It sounds like fungus gnats which are common when plants are being over-watered. Roots drown and start to rot which attracts fungus gnats. Thankfully they are easy to control but you need to back way off on the watering or the plants will die from drowning. HERE’S A LINK that describes how to control Fungus gnats. We sell the neem oil mentioned in the article.
