Scratching in the walls/ceilings

[ Edited ]

Hi. We live in suburbia, west of Brisbane, and we have something in our roof that 'scratches' and 'gnaws' (loudly) at night time. We have set 'mouse traps' and 'rat traps', and 'opossum traps', but we have never caught anything. We even put our two cats up there, for a day, and it did go quiet for a time, but the sounds are back. We have put 'baits' up there, and they are untouched. We have annual inspections for Termites and we have been 'cleared' on that score. (We do have lots of Ghekos, though.) Do cockroaches make a sound like they are chewing wood to splinters?

 

Has anyone else had this problem? What did it turn out to be? How was the problem resolved?

I'd love to hear from anyone.

I had a similar problem when I lived at Nathan. Turned out to be rattus rattus (Black rat) ... I would suggest a trap to catch them rather than bait as with a trap you know where the remains are and can remove them ...

Re: Scratching in the walls/ceilings

We get something similar from time to time in our Sydney home.  Rattus rattus is the villan.  I use the ratsack that comes in paper packets and put it in the ceiling and any wall cavities that I can access so I avoid my dog coming in contact with the bait (she's never yet made it into the ceiling space!!!).  I also put peanut butter on the outside of the paper sachets to lure them to eat it - being careful not to double dip into the peanut butter jar.  Works well even though their cousins do come to visit from time to time.  

 

Good luck.  It's an ongoing war.

Sounds more like possums to me and they probably won't eat rat bait!

Re: Scratching in the walls/ceilings

Do possums tend to get into walls and ceilings? I know they're often dancing on the roof at night but do they tend to seek shelter inside?

Re: Scratching in the walls/ceilings

I agree with Kermit. Possums sound really loud. I have occasionally seen some living in a roof spaces here in Sydney, both residential and commercial. If this is going on, they will probably leave very smelly urine & large stains showing through to the ceiling of your room/s. This is both ugly and stinky.
