## Questions & Answers

**Q: How long will it take to kill the rats. Mine keeps eating no dead body or smell found yet**
A: I found these blocks to be very efficient and fast working (have actually only used one so far).  A tiny amount had been nibbled overnight and the following morning we found a dead mouse in the next room.  I left the block in place and a couple of days later the whole block had disappeared completely!  We never did find it but didn't find any more mice, either dead or alive.  I can only assume that another mouse had found it and somehow taken it through a hole under the floorboards, which is amazing as these are big blocks! (We live in an old Victorian house with lots of drafty holes and gaps).  Mice are so small so there is not a lot of smell anyway when they die (apart from their urine) if they are under the floorboards.   I would recommend these blocks as they really seem to work well (although I still don't like killing creatures, but you can't have mice damaging your house etc :-(   )

**Q: How does rat find them if it's wrapped up do they chew through the packaging**
A: It is best practice to remove the block out of the individually wrapped red block.

**Q: Do you have to have bait station**
A: Recommend using the bait station so the rodent doesn’t spread the bait around too much,

**Q: Got a rat coming up sewer and chewing through waste pipe - will this be any good?**
A: Is it the pipe to the wc? Rats are attracted to the light so you can get a fitting that has a hinged flap which lets the waste go down but blocks out the light and won’t let the rodents through. Painting white pipe work a dark colour or using a dark coloured pipe will also help
