I was wondering if there's something safe that I could use to get rid of
gnats around my houseplants? They seem to be all over the soil on a
couple of my plants. I also have cats and a dog and didn't want to use
something that might be harmful to them. (or me!) Oh and, any ideas what
might be causing this?
Good day Pat. I would recommend safers insecticidal soap, yellow sticky
traps or diamatious earth. You should be able to find these at most
Gnats are fungus eaters. Sometimes overwatering can casuse the fungus
growth or it could of come in with the potting soil itself. The yellow
traps should work ok. This will attract them to the card and they get
stuck. The safers soap is a potassium salt?.. and it's very safe to use
around you and the pets. You will need to treat for a few days/weeks.
Diamatious earth is a product that you put on the top of the soil in your
pots. As the insects come out of the soil, the diamatious earth shreds
them to bits. If you place sand in the top in the pots, this may work also.
use one medium garlic clove, skin ON, and place stem side down into the
soil...for a 2 inch pot; 4 inch pot? 2 cloves on opposite sites; 6 inch pot:
3 to 4 cloves).
garlic WILL grow but as the garlic aroma on top will make the gnats
literally smash themselves against the windows trying to get out; the garlic
roots will intertwine GENTLY with the plant's roots and will take care of
the fungus gnat's larvae growing on the root hairs.
Spread a layer of perlite on the surface of the soil. It stays dry and
prevents the gnats from reaching the actual soil to lay eggs. The
abrasiveness prevents already hatched nymphs from creeping out. Use
yellow sticky strips to trap the gnats.
Overwatering causes this. I use product called Knock Out Gnats sold by
Garden's Alive. One bottle lasts for years. It's a strain of Bacillus
thurgiensis Israelensis, but it's the H-14 strain which is specific for fungus
gnats. It is host specific and will not harm anything or anyone other than gnat
