I’d love to speak to you about our lord and savior LECA

😂🙏 Preach!

#### Liz ha respondido el 2023-08-11

Do these prevent or get rid of gnats??

#### Brandon \& Michelle ha respondido el 2023-08-11

It’s complicated. Growing in only LECA can be difficult to learn but one of the benefits is it eliminates fungus gnats bc there’s no soil for them to populate in

#### MamaJuju ha respondido el 2023-08-12

I’ll take a pamphlet 😂

try diatomaceous earth. Had a huge gnat problem and that worked within a day.

#### Lani ha respondido el 2023-08-11

How did you use it? Did you just sprinkle a little on the top?

#### Roman ha respondido el 2023-08-16

Just lightly cover most of the topsoil of the plant and try not to water it for as long as possible after because water makes it harmless to the pests.

I used a combo of 3% hyrdogren peroxide and water. 1:3 ratio and just used it when watering to kill the larvae, plus a sticky trap to kill the adults. I didn't want to go the route of just starving them out by not watering. didn't damage my devil's ivy and it's actually flourishing now :)

#### Lani ha respondido el 2023-08-11

Did you use this once, or every time you watered?

#### klaire ha respondido el 2023-08-11

Probably 2-3 times max, but only if I noticed the larvae still crawling around on there. I think for my ivy it took twice for them to all go away

#### klaire ha respondido el 2023-08-11

but also yes, only when it was due for watering ☺️

#### Bean ha respondido el 2023-08-11

Did you use the mix in place of water? Or put some of the mix on top after watering? Or mix then water? I think I’m overthinking this lol.

#### klaire ha respondido el 2023-08-19

Kinda both?? But mostly the first - in place of water

Beneficial nematodes

I had a horrible infestation. I gave them all the hydrogen peroxide and water treatment to kill the babies and then put gravel or sand on top of all of them so the adults couldn’t get back in. Sticky traps will also capture the remaining adults. I also switched to bottom watering because fungus gnats lay their eggs in the damp soil on the top inch or two.
