🌱 Guard’n’Aid PestOFF Plus Maxi Fumer 31g — Guide and Product Information
Product Overview
Guard’n’Aid PestOFF Plus Maxi Fumer 31g is a smoke generator formulated with permethrin for use in controlling crawling and flying insects in enclosed areas. It is especially useful where access is awkward and direct spraying is less convenient, making it a practical choice for grow rooms, empty glasshouses and other difficult-to-reach spaces.
As part of the Pest Control range at Acorn Horticulture, this fumer can be used as part of a clean-up and turnaround routine between growing cycles.
Main Benefits and Practical Use
The key advantage of a smoke generator is its ability to disperse throughout an enclosed treatment area, helping reach corners, crevices and hidden spaces. This makes the Guard’n’Aid PestOFF Plus Maxi Fumer particularly useful when preparing a space before restarting cultivation or when tackling insect issues in empty growing environments.
- ✔ Helps treat enclosed areas evenly
- ✔ Targets both crawling and flying insects
- ✔ Well suited to grow room turnaround and empty glasshouse use
- ✔ Useful in hard-to-access spaces where manual application is awkward
Features and Product Range
This listing is for the Maxi 31g fumer. If you need a different treatment size for smaller spaces, Acorn Horticulture also stocks the Guard’n’Aid PestOFF Plus Mini Fumer 7g Pack of 2 and the Guard’n’Aid PestOFF Plus Midi Fumer 15g.
Choosing the right format depends on the size of the treatment area and your overall pest management plan. For monitoring flying pests alongside treatment, products such as Sticky Fly Traps Pack of 5 can also be useful.
Suitable Applications
Guard’n’Aid PestOFF Plus Maxi Fumer 31g is intended for enclosed spaces where insect control is required and access may be limited. It is commonly considered for empty grow rooms, cleared propagation areas and empty glasshouses before reintroducing plants or equipment.
Good environmental management also helps reduce recurring issues. For more advice, read our guide to the importance of proper ventilation in a grow tent and our practical article on preventing mould and mildew in your grow tent.

For best results, combine treatment with regular cleaning, inspection of surfaces and continued pest monitoring. Addressing environmental factors such as airflow and moisture control can also support a cleaner growing space over time.
