Sticky traps are glue-based traps valuable for growers and serve two purposes- to trap and monitor pests. Generally, a sticky trap is a sticky layer mounted on a piece of cardboard. They usually don’t contain pesticides though some contain aromas are infused to attract pests. They are effective in trapping airborne adult pests.
You can purchase sticky traps at The Grow Depot. Their brightly coloured yellow sticky ribbon traps are designed to attract pests. You can also find whitefly traps and Leafminer traps in their site and protect your plant from pests. Their sticky traps are eco-friendly and perfect for greenhouse, garden and farm use.
Benefits of installing sticky traps:
- Estimate pest population: Using lens you can count the number of pests and have an accurate record of number of pests and type of pests.
- Lower the use of pesticides: When regular inspections are done after installing sticky traps, there is estimated to be 50% reduction in pesticide usage. Less use of pesticides puts the gardeners/ workers to less exposure of chemicals and improves plant quality thus resulting in substantial profits for the growers.
- Warns in the initial stages of pest occurrence: Sticky traps provide early warning of pest occurrence before the plant starts showing symptoms of pest attack. More visual inspections must then be carried out and pest-control strategies must be implemented.
How many are to be installed?
The number of traps required depends on various factors including the type of target pest. In general, one sticky trap needs to be installed per 10,000 square feet. When it comes to whitefly infestations, a sticky tap per 1000 square feet is needed to get an accurate picture of infestation. Number all the traps and map their location.
Placement of traps:
The traps should be placed a little above the plant canopy and should be raised as the plants grow taller. Whilst monitoring pests like fungus, the traps should be oriented horizontally and in majority of cases, orienting the longer part of the trap vertically proves effective. Inspect the traps twice a week and replace them after visual inspections.
Can I reuse the traps?
Reusing the traps may seem cost-effective but keeping count of insects when reusing traps in labour-intensive. When left on for too long, traps are accumulated with many insects and it would be challenging to count them.
To make the counting easier, you can wrap the traps in a clear plastic and do the counting in a convenient location. Trap data alone isn’t an effective indicator of pest infestations. Traps tend to also catch other migrating insects. Talk to a specialist and determine the best course of action after visual inspection.
