## Product: Mortein Odourless Spray

## Pros
- Effective in achieving desired results
- Suitable for regular use
- Pleasant and mild scent
- Leaves no residue
- Hypoallergenic and gentle on skin

## Cons
- Reported ineffective for killing flies, requiring close proximity
- Users mention consuming half a can to kill only five flies
- Shaking the can or spraying in a cloud doesn’t improve effectiveness
- Suggests alternative methods, like using a bench spray, for better results
- Recommendation to label it as having low effectiveness for some insects

## Bottom Line

The Mortein Fast Instant Kill Odourless Spray 350g is well-regarded for its overall effectiveness and pleasant user experience. However, if you're mainly dealing with flies, users indicate it might not be your best option, as it reportedly needs close contact to work. For other insect types and general use, it performs as advertised—quick and residue-free. _If flies are your main concern, you might want to explore alternative sprays._
