Tips for Bulb Fly Control: Keep Your Garden Safe and Beautiful

Have you ever experienced a beautiful garden destroyed by bulb flies? If yes, then you know how frustrating and overwhelming it can be to control them. The good news is that you don't have to give up on your garden just yet. In this article, we will provide you with some tips on how to control bulb flies effectively.

What are Bulb Flies?

Bulb flies, also known as Narcissus fly or Onion fly, are small insects that belong to the family of flies. They lay their eggs in the soil near bulbs, and when the larvae hatch, they feed on the bulbs, which can cause severe damage to plants. The adult flies are around 6-9mm long, and they have a yellowish-grey color with shiny black stripes. They are active from March to May.

How to Identify Bulb Flies?

The first step in controlling bulb flies is to identify them. Here are some signs that your garden may be infested with bulb flies:

• Yellowing and wilting leaves
• Stunted growth
• Holes in the bulbs
• Pupae in the soil

If you see any of these signs, it's time to take action.

Tip #1: Remove Infected Plants and Soil

The first tip in controlling bulb flies is to remove infected plants and soil immediately. This will prevent the spread of the larvae and pupae to other plants. Be sure to dispose of the infected plants and soil properly, so they don't contaminate other areas of your garden.

Tip #2: Use Netting to Protect Bulbs

Another effective way to control bulb flies is to use netting to protect your bulbs. Cover the bulbs with a fine mesh netting during the growing season to prevent adult flies from laying their eggs on the bulbs. The netting should be secured tightly around the bulbs to prevent the flies from entering.
