They're back!!! The past couple nights we've been hearing 'rummaging' noises and last night my wife and I both heard squeals outside our master bedroom window on the deck area. I flipped the lights on and looked outside - sure enough a big rat came running out. I'm pretty sure there were at least two of them probably fighting with each other. My shed door was flung open but I may have left it that way when getting bug spray earlier. I thought I had closed it or at least pushed it mostly closed...wouldn't be surprised if they nosed their way in and were looking for food.

I'll have to lay some traps out. I only have two right now and am tempted to get a dozen of them. We have a small yard so I feel that many is unnecessary but what do I know...

Several months ago I was actually able to get one that was sneaking in under the yard wall through a small burrow hole. I set the Tomcat up right near where they were coming in and heard a loud snap in the middle of the night followed by high-pitched squealing that woke me up... the rat was struggling to free itself from the Tomcat when I walked outside to check, and it was pulling the trap around with it lol. I had to quickly dispatch it with a 1x6 plank, guillotine style execution.

I was looking into electric traps but those just seem cost-prohibitive. I'll probably buy at least a few more snap traps from Home Depot and line the walls and edges of shed with them. Perhaps I'll try unbaited. Right now I just have the traps laying out there for the rats to get 'accustomed' to. I'd also like to modify them by adding some screws or nails so the bigger ones can't pull themselves out if caught. I haven't caught anything on the Victor trap yet. The bars are slightly rusted too, so it's probably a good idea just to get some new ones anyway.

Wish I could poison these but the *effective* poisons are banned in CA and if you poison these things they may get scooped up by other wildlife that will then in turn be poisoned as well.

This is the stuff I have used for years.  The large bars are great because the rats have to consume them where you place them, instead of carrying the small pellets away, so you can monitor what they are actually eating.  (The line above is a link.  Don't know why it looks like that.)


I don't think the dead rodents are considered toxic to other animals because active ingredient is an anticoagulant. 


If you decide you need it I'm sure you could find a sympathetic mustachian to send a box.

Thanks! Yea looks like Ramik is OK in CA - at least when I add it to my cart on Amazon I have the ability to actually place the order.  Maybe I should pickup a box of that stuff if the snap traps aren't effective. I have both the Tomcat and modified Victor setup. I screwed the Victor to a short 1x6 plank and weighed the other side down with a brick. The Tomcat also has what appears to be an attachment loop so I passed some butcher's twine through and secured the other side to a nail I partially drilled into the same 1x6 plank. I turned the Victor into an instant death trap, adding more pressure to the springs with popsicle sticks and drilling a handful of 1-1/4" sheetrock screws from the bottom up:

I have only once encountered live rats in the snap traps.   Came down on the back of it's head and he was perfectly fine.  Pissed off but fine.  and big.   gave that one a gas pedal till he died.  Then I threw him in a bucket of water and he started swimming around.
Ratsputin!

I have seen several rats come back to life after being seemingly very dead. Itís crazy.
I had a dead rat come back and jump out of a freezer that he had been in for 2 days. Freaked the fuck out of me but one of the other scientists just laughed and said ďoh yeah, watch out for the rat zombies, they come back sometimesĒ

Oh, and rats are crazy smart, but blind as fuck. Thatís why PP above has so much success with putting unbaited traps in their known path. They literally canít really see them. They can smell bait and learn to avoid it, but they do almost always stick to the same walking paths, which are almost always up against walls, so unbaited traps on their known path really is a smart approach.

Also, yeah, you almost never have 1 rat. Theyíre ultra social, love friends, and literally go insane and die if they donít socialize enough.
They can also chew through concrete, so itís hard to plug them out of the holes that they know about, because if they are determined to get back into their home to see their friends, then they will do their best to find a way.

I worked with rats for 6 years and had them as pets for even longer. Itís made me very grateful for every time Iíve discovered mice because that has always meant that I donít have rats (mice wonít live near rats). I have a healthy respect and fear for their cleverness and adaptability...plus their zombie powers.

So I woke up to a TON of email notifications from my IP cam and now I can't go back to sleep... rats set it off. TWO of them but one leading/clearing. Pretty ridiculous but there's one (or maybe two working in tandem, one at a time) that grabbed the bait right out of the Tomcat bait cup and the other snatched the bait right out of a modified bait cup (bottle cap slid onto the Victor metal pedal notch) and was walking all over the trap (sans the screws). I've seen where it runs now and it'll run *around* the screws. It was nosing the pedal/cup but never managed to set it off. I tried using pliers to clamp down the notch as well to try to make it more sensitive but was struggling with making it *too* sensitive (that it would set off at the slightest movement, including me setting the trap). Anyway, wicked smart.

I bought 3 more Victor traps and need to put some screws in them as well. Maybe the screws I have are too long (they stick out probably more than 1/2") but I don't know if I have anything shorter. As far as the path they run, in this particular area it seems they're running all over the place and not necessarily staying by walls. They'll scurry through the open places but it's a little cluttered back there (garden cart, waste bin, shed and maybe no more than a few feet of open space). The camera is setup to a place where it can't see the *entire* area to see the path(s) they're running but they are running across the shorter open spaces it seems. In this case, any new 'obstacle' you place out it seems they'll sniff it out and not necessarily blindly cross... then again, maybe that's only because I'm putting bait in the traps. But you'd think they'd be smart enough to know if there's a new object in their path, not to necessarily cross it but sniff and check it out, then go around. I think I'll try placing an unbaited trap along at least one path I know for sure they are traveling down. I'm assuming place the trap perpendicular to the run so the rat has to cross it, with the pedal side closest to the wall? And do you still clamp the traps down to a larger piece of wood?

The other thought I have - aren't certain types of traps perhaps better-suited for the unbaited approach? Like the plastic/yellow large pedal Victor traps as opposed to the small metal plate pedal Victor traps? The only ones I have are the smaller metal plate ones. I'm gonna try another tactic of shoving a small seed in the notch and pasting peanut butter under the pedal and some against the wood board directly under the pedal, in hopes that the rat will either try to pull the seed off and set the trap off OR sniff/lick the PB and cause the pedal to release the spring. As I type this the jerk rat came back to sniff on the trap again and laugh at me.

Look at this bastard!

I wrap the bait lever with something like a baggie tie or a pipe cleaner and smear peanut butter into all the crevices.  That makes the bait stick a lot better.


Maybe you need a cage type trap, like a "Have a Heart".  I caught a heard (20+) of flying squirrels with one, but I think rats are a lot smarter. 


It might take you a while to figure out how to catch them, but after you do you'll relish the memory of the hunt.  ;)

Nice, I'll have to try that. I set up several more traps just now but probably scared off all the rats for a while lol. One of the traps I set out went off prematurely while moving it around since I was messing with the pedal notch and trying to make it more sensitive with pliers before that. I nearly snapped my fingers off a few times setting these things up haha. I haven't yet reset the other traps but may do that tomorrow and reconfigure placement of the traps. Right now it's just a mess but it's way too early to be messing around like this... I couldn't go back to sleep after initially waking up and seeing all the notifications. Maybe I should turn those off or something :P

You can also try a night vision scope and a pellet gun.  :)

LOL! I was gonna say but totally forgot! That would be ideal but this is a small enclosed patio/backyard area at my condo. I don't think I'd be able to get far enough away to where the rats wouldn't know I'm there. The angles are bad and the area pictured is a small 6x8 covered deck area. I wish I could pop them with a pellet gun but it's not gonna happen lol. I'd also risk shooting our master bedroom sliding glass door/window out.

The new setup. There's one unbaited trap out of picture because I set it along the wall to the left of the tripod/camera. The other unbaited trap is on the leftmost side and the baited trap with a sunflower seed & PB is on the right - I'm not sure if that ones really going to work but I've been watching the rat(s) run through that opening all night. The Tomcat is pretty much useless now that the bait is out of the bait cup (I didn't bother resetting it or the spiked trap just because I didn't want to 'disturb' things and wanted to add the extra traps in case these bastards start running through again, in hopes that they'll get snapped up. I didn't have time to drill any screws in either, so there's a chance that it'll get away.

What's crazy is that you'd think the traps would trip up even with a rat brushing against the bar holding the pedal up - I just watched video of the rat casually walking all over the trap, including the bar, and nothing happening. Now that trap is older and parts of the metal are 'corroded' and rough from weathering. What I probably should do is take some sandpaper/steel wool and smooth all that out - perhaps that's affecting the sensitivity.

I recall what worked the last time I got one was cheese rinds. I stuffed them into the bait cup of the Tomcat along with PB to make it stick. I have the Tomcat setup along one passageway this way so we'll see if that works. The remaining Victors I've setup in various ways: a couple are setup with cheese rinds pushed onto the notch so it'll be near impossible to remove them and then pasted PB under the pedal. One of the others I followed this guy's suggestion: https://www.youtube.com/watch?v=6surVql9hHk and then the other: https://www.youtube.com/watch?v=La-EgIsevlQ but using a small sunflower seed and no other bait around. I may sprinkle some sunflower seeds and other crumbs to form a 'trail' later on. I nearly took my finger off setting on of the traps - I hate setting these things!

GOT ONE! The Tomcat is up by 2 now.... I put some PB in the bait cup and took a small piece of cheese rind and pushed it down, then used the PB as 'paste' to keep the rind in place. Unfortunately, I didn't have recording/motion detection enabled on my IP cam as I only have it going through the night hours. And I totally forgot to snap a few 'memorial' pics before bagging the sucker. The only reason I found out about this was because I went outside to bait the areas surrounding the traps and saw the Tomcat was out of place and the twine I used to attach it to a 1x6 board was taught - shined my flashlight under the garden cart and sure enough a big ole rat. Not sure how long it was struggling as I had no idea it went off. I know there's at least one more, so hopefully I can get that one too. I reset the Tomcat so hopefully there will be another kill soon. I'm not sure how many more uses I'll be able to get out of that thing before it busts...

More activity tonight - two more showed up. One actually got caught in a Victor trap within the past 15 mins but was able to free itself and run off.... smh. This was one of the traps I setup 'out of box' without any mods other than shimming the spring for more power too. Guess it didn't get a clean hit on the head and probably trapped it on the neck/stomach or something. Had I used screws it would have pinned it down. Now all the others are probably freaked out and aren't coming back. We'll see though. I just screwed 5 screws into that trap and reset it. Gonna get to bed and hopefully wake up to some dead rats...not counting on it though.

I know you have some bad-ass rats, but I'm 100% positive one screw will hold. 


Glad to hear that the hunting is going well.  You should think about getting a camo cap and a Mossy Oak decal.  ;)

What's crazy is *another* rat came and set off the trap that had screws in it (5 of them) AND was secured down yet it got away! From the video it looks like it 'bounced' the rat off but the rat was on it. Maybe the rat was too big for the trap? I have no idea but I was perplexed (and still am just rewatching the video over and over)... I should have had two more last night but Victor has failed me, even modified. At this point I've probably screwed my chances of eradicating at least these two nuisances long-term. Not sure if more will come back or if the rest have been "warned" to avoid.

Interesting story in the Wall Street Journal today. The rats in Paris are being protected. The people there love their rats and are taking steps to keep people from killing them. I just... SMH.

Seriously... is it just me or is anyone else finding it unbelievable that the rat managed to avoid getting caught, pinned and skewered (yum) in the screw/nail-modded snap-trap like that?! It was *all over* the trap too... I'm still confused and am in disbelief.

UPDATE: another rat came by this morning but was investigating the Tomcat and avoiding the others. I don't know if it's one of the two that got snapped but I'd be in the next county over if I were them! If I had space and a pellet gun those two would be in rat hell by now.

I noticed outside our yard walls the pest control company placed two bait stations within 5 feet of each other right where the rats are running. I'm not sure if those bait stations are intended to trap rats or just provide poison so that the rats bring it back to their nest and die off. I'm not sure what kind of poison they're using if the latter too... at least here in CA

I use rat poison in home made bait stations by my firewood shelter. It (they?) eat the bait but cant remove it. I keep refilling until it isnt being eaten anymore. Repeat at intervals through autumn and winter.
Usually find a nest and dehydrated rat mummy at some stage as the wood heap gets used up.
Cant say I like having to do it, but its better than finding a live one, or hearing them partying in the roof.

Doesnít surprise me at all, unless the trap snaps their neck, the way their bodies are built, they can withstand some pretty crazy forces. Their bodies are designed to be extremely resistant to squishing, their bones are highly flexible, and their skin and fur are tough to puncture. Oh, and they donít get infected very easily so they can get pretty hurt and still recover while being protected by their friends.

They donít seem too bothered by injuries either. Iíve woken them up from majorly invasive surgery that would require a human to stay in the hospital for a week and rats just wake up and immediately get back to being their normal, perky little selves with no signs of distress or pain with just a bit of Advil gel. They showed more distress to a bad smell than they did to having their skulls cut open.

Crazy shit.

I cleaned off the Tomcat, reset it with fresh PB & cheese rind stuck in it, and then repositioned it closer to the side of the shed where the main wall is. I also removed the garden cart that was sitting there and took down the Victor trap because I don't want to mess around with resetting those and possibly snapping my fingers off... hate those things now that I've had to reset them multiple times already. I also caved and ordered a Victor electronic rat trap, now that I know there are at least two if not more of these things around. That should be coming on Tuesday but in the meantime hopefully the Tomcat will catch at least one more.

What kind of rat poison are you using? Ramik? I was reading up on that stuff and have read mixed reviews that it doesn't work or it takes forever.

"No Rats and Mice".  The active ingredient is brodifacoum which I think is an anticoagulant. Im in NZ so our regulations may be different, this is purchased from a farm supply shop.
My bait station is a 2L plastic milk bottle with the end cut off, and a hole pierced in each side. A wooden skewer goes through the holes with the bait blocks threaded on (the bait has a hole in the middle) inside the bottle.
Once the bait is being eaten I need to refill it for 2-3 days. Then it stops being eaten, I guess because they are dead!

I've been maintaining a large bucket trap filled partway with water to get rid of a family of ground squirrels that have burrowed under the foundation of the rental we are in (thankfully we don't own the place!). We caught (drowned) four so far. I think there are four more to get.

We are trying to avoid poison pellets as there are roaming cats in the neighborhood.

"No Rats and Mice".  The active ingredient is brodifacoum which I think is an anticoagulant. Im in NZ so our regulations may be different, this is purchased from a farm supply shop.
My bait station is a 2L plastic milk bottle with the end cut off, and a hole pierced in each side. A wooden skewer goes through the holes with the bait blocks threaded on (the bait has a hole in the middle) inside the bottle.
Once the bait is being eaten I need to refill it for 2-3 days. Then it stops being eaten, I guess because they are dead!

I'm pretty sure that's banned here in CA. I searched for "brodifacoum" on Amazon, added to cart, and went to checkout and it says it can't be delivered here haha. Also, I think what I'm dealing with are Norway (brown) rats which I briefly read somewhere can be resistant to anticoagulants.

EDIT: I've been reading that Vitamin D3/D is effective for killing these guys. What I'm not quite sure about is, if that's true, how much I should be using - I'm thinking to try mixing some up in PB and placing it out around the yard. I have some 5000IU softgels and also 2000IU softgels. Not sure how many of these I would need to use... has anyone tried this out before?
