Two of the most annoying bugs that I can think of (other than mosquitos) are two that we deal with in our greenhouses and our home. These two are fungus gnats and fruit flies.
If you know how annoying it is to have the little bugs swarming around over-ripened fruit on your kitchen counter, then you will also understand fungus gnats. Now, these are not the same bugs, they only look similar to the naked eye. Fruit flies can be found in your kitchen by the bananas and fruit, but Fungus Gnats love to feed on organic material on top of the soil of plants, whether they are house plants or in a greenhouse setting.
One of the best ways we have found to eliminate these pests is with sticky traps. Both will effectively get caught on the sticky surface when placed near their habitat.
For Fruit Flies set up a small bowl with apple cider vinegar and place a trap in the bowl (see video below.)
For Fungus Gnats just set the traps near the soil surface of the plant that they are affecting.
