Greenhouse Fumigator leaves no odour or visible deposits and can be used to treat a standard 8ft x 6ft greenhouse.
Kills flying and crawling insects. As with all insecticides, precautions must be taken before and during use. 
Greenhouse Fumigator:

• Can be used as the first step to deep cleaning your greenhouse, garage or outbuilding
• Kills flying insects, ants, cockroaches and other crawling insects
• Contains permethrin

If you have foraging bees in your garden or a bee hive, extra precautions need to be taken to prevent harm to bees. The fumigator should only be used indoors and instructions followed carefully. Once the area has been treated, ventilate the area thoroughly. Ensure no animals or persons are in the area during treatment.
Where possible, avoid breathing in the vapours and keep away from heat, hot surfaces, sparks, open flames and other ignition sources.
Always use biocides carefully and keep out of reach of children.
