## Questions & Answers

**Q: Can you confirm i will receive the yellow version pen as shown or a black one please**
A: I ordered one fly killer ( yellow) and one insect killer ( black) but received two black insect killer. However I kept both as the black states that it kills flies as well as ants and other creepy crawlies. I put it around the edges of my windows and it certainly kills flies. I have to go around sweeping their bodies off the windowsills regularly.    I hope this helps

**Q: I know it's not marketed as treatment for spiders, but has anyone had experience with spiders?**
A: Spiders are ok, they don’t do any harm. Just put them outside. It wouldn’t kill ‘em anyway because it didn’t kill anything else. The spiders maybe aren’t everything but they do kill flies.

**Q: What's the active principle?**
A: The active ingredient is Cypermethrin 1.5%w/w.  There are precautions for use printed on the packaging and it is probably not a good idea for use where young children could come into contact with the surfaces which have been treated.  However, it does work and as long as you adhere strictly to the instructions, as far as I am concerned, using this is preferable to flies and insects invading your home.

**Q: Would this product also work on spiders?**
A: Had a couple of tiny spiders die but tbh they don't go near it.  Maybe Google the chemical and see if it what it says.

## Customer Reviews

### ⭐⭐⭐⭐⭐ I need another
*by B***Y on 24 July 2023*

I ordered what I thought was this but it was an aerosol spray which I am trying to return. When will I be able to buy another of these very useful items.

### ⭐⭐⭐⭐⭐ Easy to use and store when travelling
*by M***N on 3 August 2015*

Used this with other rentokil fly repellants and it seemed to work. Did not see any ants or spiders around the windows that had this on them. Used in Brazil and am quite afraid of spiders but with using this fly killer pen i did not see any spiders around the windows at all.Will use more often especially when travelling

### ⭐⭐⭐⭐ Works well but expensive
*by N***Y on 1 August 2018*

No nasty fumes and easy to use.Smeared on window sill not glass as it leaves visible mark. Works well flies land on smear than die. Great for keeping fly population down but not instant. Container felt half full but realised only 30mls.
