https://achilleagway.com/catalog/product/117325/bayer-advanced-2-in-1-insect-control-plus-fertilizer-spikesUgg so frustrated. For 4 years I used the above product before bringing inside the house my tropical plants I put outside in the summer. No fungus gnats in the house for 4 years. Now, my state has banned it...imho an over reach. Since the chemical banned supposedly may impair pollinators. Well, I don't harvest pollinators inside my house and put the sticks in the pots inside only.
Now we have a gnat of some kind infiltrating the house as the product above could not be delivered.
Have been studying the difference between drain flies, fruit flies, and fungus gnats. These are hard. Don't think they are drain flies or fruit flies..my kitchen is clean and my drains have been cleaned.
anyway, they don't bother me that much but my son hates insects..typical fruit flies and such will disappear within a month. But, this has been going on too long. I brought my plants inside I believe in September.
My search will continue for any of the 3 above and have ordered mosquitoe bits from amazon for my plants as an alternative and have also e mailed Bayer for their own recommendation given their product can't be delivered here.
