Small Bugs
Posted by Paul Spagnotti (yooper38_2000@yahoo.com) from Upper Michigan on 2002-06-29 13:59:14

We have about 14 house plants and there are these small flying bugs around the plants and soil. We have changed the soil in all the plants and even baked the soil to kill whatever else was in the soil as far as bugs. But there are still small flying bugs. How do I get rid of them?

    Hey there don't you remember the stuff I learned to make in washington?
    Well mix some Dawn soap and tobacco juice with water and spray the plants with that. also the lawn can be sprayed with a mixture of 1 can dark soda (coke works best) 1 can beer, 1 cup dawn, 1 cup tobacco juice.
    to make tobacco juice use 1 cigar or 1 pack of reg, smokes and 2cups of water. boil the smokes for 20 minutes and let set 1 hour strain the juice from the leaves. now pour the mixture in a sprayer that you hook a hose to and set for 2 tbsp. there you go.

    Adult fungus gnats fly around and are an annoyance, but they are not harmful to people. Each gnat lives for about 5 days. The trick is to get rid of the next generation - the gnat larvae that live in the top layer of the soil. The larvae feed on decaying organic matter. Decaying pine bark in potting mixes and decaying plants roots feed the larvae.

    Try to keep the soil as dry as possible. Remove all loose soil from the surface and put a light layer of coir (coconut husk) or sand or diatomaceous earth on the soil surface. These substances have sharp edges that carve up the larvae. Another safe technique is to place ½ inch slices of raw potato on the surface of the soil. After a day or so, discard the slices along with the larvae inside. Repeat this until there are no more larvae in the potato.

    Detection trick: Add a little water to the soil and then look very closely for tiny fungus gnat larvae swimming in the water as it pools on the surface. You need good light and good eyes to see them. If you don't, then your plant is probably gnat free.

    Prevention is often the best remedy. Use sterile potting mixes that are free of bark chips. The potting mix should have ample drainage material, such as perlite so that it drains well and allows the soil to dry out frequently. Fungus gnats can nearly always be traced back to overwatering and/or poor soil quality.
