I really want to use in my sealed garden nursery with 650 plants that I grow and sell. Will this kill or harm them, slow plant growth in any way? 🙏Xx

Thank you for your query. This product is the refill for ZER740 Knockdown Mosquito Killer. This product will just deter/killing flying insects on contact. It will not harm the plants in your nursery. Please ensure no plants are directly positioned in front of the plug in unit however. Please do not hesitate to contact us with any further queries.

Can it be plugged into a uk shaver socket?

Thank you for your query. If you have an adaptor plug to enable the 3 pin pug on the repeller, and have checked the voltage of the shaver socket compared to the product, this will be fine to use in a UK shaver socket. However, we wouldn't advise you do this as the product will not work very well in a damp room or a room with steam or high moisture. It is best used in a room such as living room, or bedroom, or caravan. Please do not hesitate to contact us with any further queries.

Does this fit a boots repel diffuser?

Thank you for your query. Unfortunately we cannot comment on other brands which aren't STV products, This is made for the ZER740 Knockdown mosquito killer. Thank you

Has anyone found these helpful against carpet/clothes moths

Not sure if they work for those insects however we are currently vacuuming everyday to remove the multiple, a lot, mosquitoes it kills off
