Atticus Pyrus TR Greenhouse Fogger (2oz) – Total Release Pyrethrin Insecticide/Miticide – Controls Mites, Thrips, Aphids, Whiteflies, and Fungus Gnats (Packaging May Vary)
This total release fogger from Atticus offers a potent combination of 4% pyrethrin and 16% piperonyl butoxide, making it highly effective against a wide range of pests like mites, thrips, and aphids. Compared with the Atticus Ascertain TR, which uses bifenthrin, Pyrus TR’s dual-active formulation accelerates pest knockdown and extends residual activity, but it might require careful ventilation due to the potent insecticide. Its micro-sized particles ensure full coverage over and under leaf surfaces, reaching pests in hidden spots. This product is ideal for growers with a variety of crops—flowers, ornamentals, edibles—who need quick, broad-spectrum control without complex setup. However, because it’s an aerosol, it’s less suited for large, high-ceiling greenhouses or spaces with sensitive plants that could be affected by the potent insecticides. Expect an easy, ready-to-use application for spaces up to 3,000 sq ft. The product’s main strength is its fast action and extensive coverage, but the tradeoff is the need for proper ventilation and cautious handling due to chemical potency.
Pros:- Effective broad-spectrum control with dual-active ingredients
- Complete coverage over and under leaves due to micro-sized particles
- Convenient aerosol format for quick application
Cons:- Requires proper ventilation after use due to potent chemicals

The Hurricane Ultra II stands out for its rugged, durable design and ability to dispense both oil- and water-based products efficiently. Compared with the Atticus Pyrus TR, which is ideal for small spaces, the Hurricane Ultra II is built for larger, commercial settings requiring extended run times and a higher volume capacity. Its three chemical-resistant nozzles provide precise control of droplet size, adjustable from 10 to 50 microns, ensuring optimal coverage and penetration into dense foliage. The blower’s wide dispersal pattern allows for fewer passes over large areas, saving time and labor. Its lightweight, portable design, with a comfortable handle and 1-gallon tank, makes it easy to maneuver in big greenhouses or outdoor environments. It’s perfect for professionals needing reliable, heavy-duty fogging, but it’s less suitable for small-scale growers or those preferring battery-powered units.

This multi-pack of Atticus Pyrus TR foggers extends the same effective broad-spectrum pest control as the single can, but at a more economical per-use price—ideal for larger operations. In comparison to the Hurricane Ultra II, which offers professional durability and larger capacity, the Pyrus TR pack is designed for growers who prefer a simple aerosol format without the need for extensive equipment. Each 2-ounce can treats up to 3,000 sq ft, making it suitable for medium to large greenhouses when used appropriately. Its formula, containing 4% pyrethrin and 16% piperonyl butoxide, provides fast knockdown and residual control, especially under difficult-to-reach pests like undersides of leaves. The convenience of multiple cans allows flexible application schedules, but the aerosol format might be less effective in very large or high-ceiling spaces where larger foggers or ULV systems excel. Its affordability and ease of use make it a good choice for budget-conscious growers managing multiple spaces, though careful handling and ventilation are needed.

How We Picked
To determine the best greenhouse foggers, I evaluated each product based on coverage area, ease of use, effectiveness against common pests, build quality, and value for money. I also considered the versatility of application, natural versus chemical formulations, and user feedback. Products were ranked to balance performance with affordability, ensuring options for different grower needs—from hobbyists to commercial operations. The top picks stand out for their reliability, coverage, and ability to handle various pest challenges efficiently.Factors to Consider When Choosing Best Greenhouse Foggers
Choosing the right greenhouse fogger involves more than just looking at specs. Understanding key factors like coverage area, application method, and formulation can help you make smarter decisions and avoid common pitfalls like under- or over-application. Considering these factors ensures you select a fogger that aligns with your pest control needs, budget, and grow setup.Coverage Area and Capacity
Matching the fogger’s coverage to your greenhouse size prevents waste and ensures effective pest control. Smaller units, like 2oz cans, are suitable for hobbyists or small setups, while larger, bulk foggers or ULV systems are better for commercial operations. Overestimating coverage can lead to ineffective pest control, while underestimating may cause overuse of chemicals, increasing costs and risks.
Application Method and Ease of Use
Ease of application varies significantly. Handheld or portable foggers like Hurricane Ultra II offer quick setup and mobility, ideal for spot treatments or small areas. Larger, automated foggers require more setup but provide consistent coverage for larger spaces. Consider your technical comfort level and the frequency of use—some models demand more maintenance or calibration than others.
Formulation Type: Chemical vs. Natural
Natural formulations like pyrethrins or botanical insecticides appeal to growers seeking organic or residue-free options. Chemical foggers with bifenthrin or chlorfenapyr tend to be more potent and longer-lasting but may raise concerns about crop safety or residue. Balancing pest pressure with crop sensitivity is critical when selecting a formulation.
Particle Size Control and Targeting
Adjustable particle size foggers, such as the Hurricane Ultra II, give you control over droplet size, impacting penetration and coverage. Finer mists are better for reaching small crevices and pests on foliage, while larger droplets settle faster and are suited for surface pests. Understanding your pest profile helps in choosing a fogger with appropriate particle size options.
Cost and Value
Budget considerations play a significant role. While bulk packs or more advanced foggers cost more upfront, they often provide better value for large or frequent applications. Conversely, small, inexpensive units may suffice for occasional use but can become costly over time if they require frequent reapplication or replacement.
Frequently Asked Questions
Can I use greenhouse foggers during the flowering stage of plants?
Using foggers during flowering requires caution, especially with chemical formulations, as residues can affect fruit quality and safety. Always check the product label for crop safety guidelines and recommended application timings. Natural options tend to be safer, but even then, it’s best to apply when plants are least sensitive and to allow sufficient drying time before harvest.
How often should I reapply a greenhouse fogger for pest control?
The frequency depends on pest pressure and the formulation used. Chemical foggers often require reapplication every few days or weekly for persistent infestations, while natural options might need more frequent use. Always follow label instructions and monitor pest levels to avoid over- or under-treatment, which can compromise effectiveness.
Are foggers safe for use around edible crops?
Many foggers are designed with food safety in mind, especially those labeled for fruit and vegetable areas. However, it’s vital to follow the manufacturer’s instructions regarding pre-harvest intervals and application methods. Natural or botanical foggers generally pose fewer risks, but proper drying time is still essential before harvest to prevent residues.
What’s the advantage of an adjustable particle size fogger?
Adjustable particle size foggers provide greater control over droplet size, which can improve coverage and pest targeting. Finer mists penetrate dense foliage and reach pests hiding in small crevices, while larger droplets settle faster for surface pests. This flexibility helps optimize pest control effectiveness across different greenhouse conditions.
Is it better to buy a single large fogger or multiple small units?
The choice depends on your greenhouse size and application frequency. Large, single units or bulk packs often deliver better value and uniform coverage for sizable operations. Smaller units are more portable and easier to handle for spot treatments or small setups. Consider your workflow, budget, and pest management needs when deciding between the two options.
Conclusion
For hobbyists or small-scale growers, a compact and easy-to-use fogger like the Atticus Ascertain TR offers reliable pest control without complexity. Commercial growers or those managing larger spaces should consider bulk packs such as the Atticus Pyrus TR for value and coverage. Growers prioritizing natural solutions might prefer the BASF Pyrethrum TR Fogger, while those needing adjustable particle size and precise application will find the Hurricane Ultra II indispensable. For beginners, simplicity and safety are key, so choose options with straightforward instructions. More advanced users seeking maximum control may opt for professional-grade foggers with adjustable settings. Matching your grow setup and pest pressure with the right fogger ensures effective, safe, and cost-efficient pest management.
