INSECT FLY TRAPS PACK OF 7

Description

Insect Fly Traps Pack of 7 provides a full season of fungus gnat and flying insect monitoring and control for indoor grow rooms, propagation areas, and greenhouses. We have been recommending sticky insect traps to UK growers since 2017 as an essential first line of defence against flying pests — monitoring traps are the earliest warning system available for detecting new infestations before they establish and become difficult to control.

Why Sticky Fly Traps Are Essential for Every Grow Room

Fungus gnats (Bradysia species) are one of the most common and frustrating pests in indoor growing environments. Their larvae feed on root hairs and beneficial microorganisms in the root zone, causing wilting, nutrient deficiency symptoms, and damping-off in seedlings. Adult gnats are attracted to the warm, moist conditions of any indoor grow and can travel long distances to find suitable breeding media. Yellow sticky traps exploit the strong attraction adult fungus gnats have for the colour yellow, drawing them in and trapping them permanently before they can breed in your growing media. This both removes breeding adults from the population and provides you with an accurate count of how severe an infestation is, allowing you to judge whether additional control measures such as biological nematodes or Bacillus thuringiensis var. israelensis (BTi) are required. The pack of 7 provides continuous coverage across a growing season or enough traps to monitor multiple areas simultaneously.

How to Deploy Insect Fly Traps Effectively

Position yellow sticky traps at substrate level — just above the surface of the growing media — where fungus gnat adults are most active as they emerge from the substrate to mate and re-enter to lay eggs. For monitoring purposes, one trap per pot or per square metre of growing area is a good starting point. Replace traps when the adhesive surface becomes covered with insects or debris, typically every 2–4 weeks. Inspect traps regularly to identify pest species early. For broad-spectrum flying insect control in larger spaces, hang additional traps at mid-canopy height to catch whitefly and aphids which tend to fly higher than fungus gnats.

Combine Insect Fly Traps with nematodes, BTi products, and sticky collars around container bases for a comprehensive integrated pest management approach to fungus gnat control. Browse our full pest control range for biological and chemical control options.
