Therefore , keeping new or infected plants inquarantinecan be very in force at melt off the spread of fungus gnat to other potted plants . That way , you could focus your intervention on just one plant rather of them all ! For severe infestations , some folks may choose to completely remove the infected plant from the firm .
5 WAYS TO GET RID OF FUNGUS GNATS
1) Eliminate Excess Moisture
At the first star sign of a fungus gnat issue , this should be the initial footmark . permit the top few inches of the plant ’s territory to dry out . This will make the soil untempting to adult flies , forestall them from laying more eggs . If you ’re lucky , this can kill a mickle of the testicle and larvae too ! what is more , eradicate standing water . This include in the pot drainage tray , or even from other generator nearby – such as leaky pipe , condensate puddle , and so on .
2) Sticky Traps
Fungus gnats are drawn to light , as well as the colour xanthous . Use yellow embarrassing sand trap near , attend from , or inside the potted plant to catch adult fly . These sticky traps on stakesare project specially for potted plants ! We also hangthese large onesto catch gnats and other flying pests inour greenhouse .
However , keep in mind that fungus gnats expend the legal age of their lifecycle as ball and larvae , so gluey traps will only serve a constituent of the trouble right aside . If the adult flies have already laid more testis , the bike will continue . Yet reducing the grownup fly population with sticky traps does help put a dent in the problem overall ! Continue to use sticky traps forseveral hebdomad to to the full go the cycleand get rid of fungus gnat .
3) Use Hydrogen Peroxide to Kill Fungus Gnats
If the dim-witted combination of dry out the territory and hanging a few viscous traps does n’t get the business done , there are severalnatural and non - toxicproducts used to down fungus gnats as well . One pick is to utilize something you probably already have around your house – H hydrogen peroxide ! The in force tidings ? It is pronto available , well-to-do to work with , and wo n’t harm your house plants . The best newsworthiness ? Hydrogen peroxide reportedly kill fungus gnat eggs , larvae , pupae , and adult flies on contact . arrivederci , sucker .
To make a hydrogen hydrogen peroxide resolution , first be trusted you ’re using the distinctive 3 % household hydrogen hydrogen peroxide , not the industrial - strength hooey ! Dilute it down slightly andmix 1 part 3 % atomic number 1 hydrogen peroxide to 4 parts water(e.g . 1 cup peroxide and 4 loving cup water ) .
tolerate the soil to dry slightly before app . Then , either spray the surface of the soil exhaustively until it saturates down a duet of inches . Or , for a deeper and more effective treatment , water the entire plant with it – soaking all of the dirt . It will fizz and froth , which is totally normal . It quickly breaks down into molecules of water and oxygen , which clearly are n’t a danger for plant !

4) Biological Control of Fungus Gnats – Bacillus Thuringiensis
Another non - toxic way to care for fungus gnats is to use biologic control , such as Bacillus Thuringiensis . Specifically the subspeciesisraelensis , also known asBti . Bti is a by nature - occurring bacteria that is found in dirt . accord to the EPA , Bti curb spores that bring forth toxin that specifically target andonlyaffect the larvae of the mosquitoes , bean aphid and fungus gnats . substance , it is not harmful to other organism .
You may have heard us talk about Bt before , but note that there are a few different types of Bt ! Bti is the one that is effective against fungus gnats , whilethis Bt product(Bacillus thuringiensis kurstaki ) fair game cat such as moolah moth worms and lucre measuring worm , but is ineffectual at killing fungus gnat .
To apply Bti , follow the instructions for a“soil drench ” on the product that you purchase . It is unremarkably advocate to irrigate the plant with the solution , since only spraying the airfoil of the soil may not penetrate deep enough to kill all of the fungus gnat larvae . repetition as needed , follow the instructions . Another popular option is call “ Gnatrol ” .

5) Neem Oil Soil Drench
In a exchangeable method to H peroxide or Bti , a neem oil drench can also be applied to the infected soil to kill fungus gnat . Do not apply flat hard neem oil though ! make and apply a dilute neem oil solution by follow the manufacturer ’s instructions on the neem fossil oil product you choose . Watering with a dilute neem fossil oil solution can aid to pop fungus gnats , and also fight off them in the future .
When shopping for neem fossil oil , I always suggest pick out ahigh quality cold - exhort stark neem oilover pre - miscellaneous Cartesian product that contain a lot of other additives . to fully combine neem oil with water for an even and in effect covering , the neem oil will need to beemulsifiedfirst – because oil and body of water do n’t well fuse . Check outour clause all about the right way mixing and using neem oilin the garden , or , for houseplants !
