Where Do They Come From?

Knowing how these pests get into your home is the first step in prevention.


Fruit Flies:

  • Attracted to ripening or rotting fruits and vegetables

  • Can come in through open windows or on produce from the grocery store

  • Thrive in garbage disposals, trash bins, compost bins, and sugary spills


Fungus Gnats:

  • Most commonly come from infested potting soil or overwatered houseplants

  • Eggs and larvae live in damp soil rich in organic matter

  • Overwatering or lack of proper drainage creates the ideal breeding ground

Where You’ll Find Them in the House

  • Fruit flies tend to hang out in kitchens , especially near fruit bowls, trash cans, drains, and any area with fermenting food.
  • Fungus gnats live in and around indoor plants , particularly those with moist, organic-rich soil. You’ll spot them near plant pots or flying around leaves.

FAQs

How do I use Arber’s Organic Bio Insecticide and Sticky Traps to get rid of fungus gnats?

To effectively get rid of fungus gnats, start by treating the source: the soil. Arber’s Organic Bio Insecticide should be diluted according to the label instructions and sprayed directly onto the top layer of your plant’s soil. This targets the larvae hiding beneath the surface.

Next, place Arber’s Sticky Traps in the soil around the base of the plant. These non-toxic traps attract and capture adult gnats, helping break the life cycle. Repeat the spray treatment weekly as needed and reduce overwatering to prevent future infestations.

How does Aunt Fannie’s FlyPunch work to eliminate fruit flies?

Aunt Fannie’s Fruit Fly Punch is a pre-mixed, ready-to-use solution that naturally attracts and traps fruit flies using a powerful vinegar-based formula. To use it, simply open the bottle and place it near areas where you’ve noticed fruit fly activity — like fruit bowls, kitchen counters, trash cans, or compost bins.

There’s no setup or cleanup involved. Fruit flies are drawn to the scent, enter the trap, and are unable to escape. Replace the bottle every 30 days or as needed during peak infestations.

How can I tell the difference between fruit flies and fungus gnats?

Though similar in size, fruit flies and fungus gnats have key differences in appearance and behavior. Fruit flies are tan or light brown with red or dark eyes and tend to hover around fruit, trash, or drains — especially in the kitchen. Fungus gnats , on the other hand, are darker (gray or black), have longer legs, and are commonly found flying near houseplants or crawling on moist soil.

If you see bugs flying near your fruit or garbage, it’s likely fruit flies. If they’re coming out of your plant pots, they’re probably fungus gnats.
