By catching any issues early on, you can take immediate action to prevent further damage.

Use sticky traps

Using sticky traps is an effective and non-toxic method of monitoring and trapping pests in your greenhouse. Place these traps strategically around your greenhouse, especially near vulnerable plants or areas prone to infestation. The traps will capture flying insects, providing you with valuable information about the type and severity of the pest problem.

Keep a record of observations

Keeping a record of your observations is an excellent practice for greenhouse pest and disease prevention. Note down any changes you observe in your plants, any unusual behavior, or signs of infestation. This record will help you detect patterns or identify potential risk factors. Referencing your observations can also guide you in implementing appropriate control measures.

Implementing Biological Controls

Introduce beneficial insects

Using beneficial insects is an eco-friendly and effective method of pest control in your greenhouse. Introduce natural predators like ladybugs, lacewings, or predatory mites to help control common pests. These beneficial insects feed on pests, reducing their populations naturally. This approach reduces the need for chemical insecticides and promotes a more balanced ecosystem.

Use biological pesticides

Biological pesticides, derived from natural sources, can be an effective tool in greenhouse pest control. These products target specific pests while minimizing harm to beneficial insects and the environment. Consider using botanical extracts or microbial-based pesticides, which provide targeted control against pests without posing significant risks to your plants.

Encourage natural predators

Creating a friendly environment for natural predators can help control pests in your greenhouse. Provide shelter and food sources for birds, lizards, or frogs, which are natural predators of many greenhouse pests. Install bird feeders or birdbaths to attract birds, and create hiding spots using rocks or mulch to attract lizards and frogs. By encouraging natural predators, you can establish a natural balance and reduce the pest population.
