Terad3 Blox by Bell Labs features the newest formulation in the fight against rodent infestations, using a whole new active ingredient: Vitamin D3. This new Vitamin D3 bait kills anticoagulant-resistant rats and mice (those resistant to other baits such as Contrac) and substantially reduces the risk of secondary poisoning. Terad 3 also poses a low toxicity to birds. The bait features a dense, tightly compacted 1 oz. bait block with superb durability, mold and moisture resistance and the ability to remain stable in temperatures as high as 200F. Best of all, with Terad3 you get a highly palatable and attractive rodent bait that rats and mice just can't resist. Available in 4 lb. and 18lb. pails of 1 oz. blox.

    1 of 5 stars  Stop-Feeding Action
    By in Northridge, CA on 07/31/2013

    This is not a rating but rather an information bump for those gave this a 1 star rating. The reason the bait is not eaten as much as the other baits you used is because Terad is a stop-feeding bait. After a lethal dose the rodents "stop feeding" , they do not eat anything, and die in about 1-3 days. You will not use as much of this bait or any "stop-feeding" baits as opposed other baits that are anticoagulants. That's all =)

    Goodbye Mr. mouse and Mr. rat. The are dying quickly. We have dogs that catch them and think they are tasty treats so its WONDERFUL to finally find a product that won't kill my animals when they get a hold of a poisoned rat or mouse. I also got the bait stations to keep the bait out of reach, they are well worth it. Also the blocks are a much better idea as the pack rats carry off the small stuff to who knows were for your kids or dogs to find it later.

    5 of 5 stars  Works for me
    By Dino in Californis on 07/29/2012

    I have been using Terad3 Blox for about 6 months. I leaned about it from my exterminator who was charging me 40 bucks a month for bait boxes. I bought a 4 pound pail of the bait and 4 metal bait boxes for about 100 bucks. Should last me a year. We have a problem with roof rats and they seem to love it! I have to replace the bait every two months. Haven't seen any dead ones around. But I have not seen any running the fence like I used to. Tip: roof rats are very smart and they don't like new things. Set your boxes and leave them alone for a couple of months. They will find it.

    These blocks work wonders!! I do rat and mouse jobs all the time and never use the poisonous garbage blue blocks. I have heard how it kills non target species like birds of prey, dogs, and even cats. Whatever will eat a sick mouse or rat dies from using poison. I love this product and on my 4th 5 gallon bucket.

  • 2 of 5 stars  Mice Prefer Rice
    By Julie in Pearland on 05/18/2017

    I have filled and placed four bait boxes. Three outside in the back yard where we can hear the mice and rats chirping and one in the kitchen pantry after noticing that they had chewed through a bag of rice located there. The next day, a mouse ran out of the pantry when I opened the door! I was hoping that it ate the bait and would die soon. NOT! The day after that, there was rice all over the items in the pantry all the way to the floor. I had to throw the rice away. The new bag had feces and urine on it. Yuck! Now that the rice is gone, hopefully, they will eat the bait. May have to switch to traps or sticky pads.

    Expert Response   Expert response:
    We are sorry to hear that the Blox is not performing up to your expectations. Rat baits are terrific tools to use in a rat treatment program. Unfortunately, competing food sources will always be an issue with rats choosing the bait over the new food source. It is important to know that some species of rats can take several weeks to eliminate them with baits. During this time all competing food sources should be kept in sealed containers. We do hope this information helps and you continue to use the Blox until all of the rats are gone. Please let us know if you have any questions. We are always happy to help!

  • 5 of 5 stars  Follow Up of earlier reivew.
    By Kyron in Enterprise, AL on 02/06/2017

    i submitted a review a few days ago and this is a follow up: today was day 5 after 4 nights of having the Terad3 Blox and bait stations in my chicken breeding barn, today while feeding i found half dozen or so rats and mice laying dead around the inside of the barn so not only do these blocks get ate if you place your bait stations strategically along the walls but they'll also be dead within a few days. i've still got 3 of 4 stations set out that have 100% of the blox consumed nightly and about 40-50% in the last one. i'm just about out of the 4lb bucket, as soon as the 18lb one arrives i'll fill the other two stations and place them in storage buildings i've got on the property that i'm seeing some signs of rodent problems in with this cooler weather we recently had.

    5 of 5 stars  Only time will tell but.........
    By Kyron in Enterprise, AL on 02/04/2017
    Verified Purchase

    I'll start my review by saying, I've read the reviews here and on other sites and all the negative ratings are based on the product not being eaten at all it seems. I have a 30x72 chicken breeding barn (not a poultry house, an in demand breeds setup) with about 400 birds in it. i never had any significant rat/mouse issues till they came in at the end of summer and clear cut the 106 acres directly behind my barn, then when the weather turned cold i got flooded with them, they were everywhere. the intended use of the Terad3 Blox included 'Agricultural and animal production facilities' so i hesitantly placed an order for a 4lb tub along with a 6 pack of the B&G Rodent Bait Station Cafe on a Saturday afternoon. the bait stations came UPS on the following Tuesday and the Blox by USPS on Wednesday. I took them Thursday morning and installed 4 of the bait blocks into each of 4 stations spaced out along the pen walls inside the barn, i didn't bother to check them till Saturday morning, the first station i checked was near my feed barrels (sealed plastic drums), it had over 50% of all 4 blocks eaten and a good bit of rat droppings inside the station. the other 3 stations had 100% of all 4 blocks eaten and lots of rat droppings inside the stations. i cleaned them all out, refilled and ordered the 18lb tub!!! as much feed as the chickens scratch on the floor and make a mess out of there's plenty of stuff for rats to eat and i was skeptical they'd eat these blocks but i was presently surprised. IF you're not getting your blocks eaten by mice, i'd venture to say you don't have your stations strategically placed along walls (the natural path of rodents).

  • 5 of 5 stars  Great Rat War of 2016
    By Mike in Lawton, Ok on 01/28/2017

    I've always had a minor mouse problem, but one night I heard a loud hissing noise that had me out of bed in a flash! It seems rats found a way into the house and one got smacked by an old school mouse trap. He was so large the trap just hurt him and made him angry as he forced his way from the trap, hissing. I gave him a hammer so he could commit suicide rather than live a life in pain. Fast forward to my delivered package of Terad3 blox and Protecta Rat Bait Station.... I filled one station with blox and put it outside in the barn. The other was (hopefully) temporarily put near the area where the rats were getting in the house. 24 hours later the barn station was empty and the station at the house was about half eaten! I kept the stations filled for three days, each time about the same amount eaten. I was afraid it wasn't working, and I was leaving the house for three weeks. When I returned home, the barn station was empty (again) but the house station was the same as I left it. I'll be filling the barn station again, but I think the war is over! No more signs of rats in either location.....it seems it worked on the mice as well, Terad3 blox works!

QIs Terad 3 safe to use with pets, specifically from secondary poisoning?

ATerad 3 is very popular because of the reduced risk of secondary poisoning.  A pet would have to eat a large amount of the actual bait to become very ill.  In turn, a pet would have to eat a huge number of rodents that ate a small amount of bait to become ill.  Most pets don't eat dead rodents....they may bring them to your doorstep but most do not consume the carcass.  Of course you must do your part and use discretion on where you place the bait for the rodents so it is out of reach of children and pets.

QWhat happens to the mouse after it eats Terad 3?

ATerad3 causes hypervitaminosis (vitamin poisoning) which in turn causes calcification of the rodents heart, lungs and other important organs which of course leads to death.

QDo you carry a mouse bait that wouldn't be harmful to my dogs if they ate a poisoned mouse?
We are trying to take care of a mouse problem in our attic. What is your suggestion on eliminating these pests without harming my dogs if they were to eat a poisoned mouse?

AWe would recommend our new rodent bait from Bell Products called Terad3 Blox.  It is a new organic rodent bait that significantly reduces the risk of secondary poisoning.  Also, a dog or cat would have to get a hold of numerous dead rodents to feel the effects of a rodent bait, usually more than 10, and the pet would have to actually consume the entire rodent.  Most pets might play around with a dead rodent, but not consume it.

QCan the Terad3 Blox be used in the Protecta Evo bait station (with key)?
or do I need Fastrac? I haven't seen mice yet this year, but closed off two holes to garage where I found dead mice a few months ago. Since Fastrac is more expensive, if Terad3 is as effective, I would order that. However, I want to do it right the first time so if I need Fastrac please let me know. Please advise as to the effectiveness of Terad3 versus Fastrac. Thank you!

AFastrac and Terad3 Blox are both very effective rodenticides. However, there are pros and cons for each of them. The Pro of Fastrac is that it does provide you with the fastest kill of rodents (normally within 12-48 hours after feeding) but because Fastrac is a faster kill it does not have an antidote available to stop an untargeted poisoning. Terad3 Blox has shown great bait acceptance and has low toxicity to untargeted animals or birds and a great price point.

QWhat type of poison will just cause rats to bleed & not kill owls if they eat a dead rat?
My bait station is a 4 inch tube with a tee and bait can be poured in top to settle in the middle of tube. I don't want an owl or hawk to die if they eat a dying rat?

QIs Terad3 Blox safer for large dogs who eat very large field rats?
I own imported Large boned Dobermans for show. The bad thing is they constantly "hunt" rats and willfully consume the whole thing. I currently have an infestation of very large field rats in the crawlspace. Any suggestions for how to to get rid of the large rats, yet keep my dogs safe?

A

Terad3 Blox is an excellent bait choice if you are concerned about secondary poisoning, such as your dogs eating rodents that have consumed the bait, since it is designed with this type of situation in mind. Of course, you should always use baits in tamper-resistant stations and store baits out of reach of children and non-target animals. For indoor areas such as a crawl space, we would recommend using traps such as the Catchmaster Easy Set Rat Snap Trap so that you can easily locate and remove dead rodents. Please see our Rat Treatment Guide for additional tips and information.

QDoes Terad3 Blox cause dying rats to search for a water source like previous poison?
I have a koi pond and am concerned that will go to it for water and die there.

AThere are no products on the market like what you speak of.  It has been a myth for years that a product like this exists, but it does not.  Terad 3 causes death by an accumulation of calcium in the internal organs and would be safe around a pond as long as the product is not able to get into the water itself.

QOutdoor voles and field mice.
Does this product work in outdoor settings with tunneling rodents. If so, which form would be better (~ 100 tunnels of voles and field mice) the pellets or the blocks?

ATerad3 Blox are not specifically labeled for voles. We would recommend using Kaput Rat and Mouse Bait. They come in place packs that are in pelleted form. This is best for voles in particular. It will also work very well for mice. For voles, open a pack and load one ounce (half of a pack) of bait into each bait station. Situate bait stations near runways, burrow openings or plants that voles have been damaging. Maintain a fresh supply of bait for 15 days. Use a tamper-resistant bait station when children, pets, or non-target wildlife are present. For mice, open a pack and apply 1/4 to 1/2 ounce of bait per placement at intervals of 8 to 12 feet. Maintain a fresh supply of bait for 15 days. First dead rats, mice and voles will appear 4 to 5 days after feeding begins. Always follow label directions.

QIs cholecalciferol really safe?
I started using rat baits with vitamin D3 years ago because I have cats and dogs and was worried about their safety. I used the Rampage packets with good results killing rats and even had a dog eat one of the packets with no ill effects. I was just about to reorder for the first time in several years and read on a pet poison web site that calls it one of the most dangerous poisons of the market as there is no remedy for the kidney failure it causes if symptoms go unnoticed for a few days. If pets (8-75 lbs.) cannot access the poison, is there really a risk they could die from eating dying rats? (My dogs will happily eat rats if they can catch them.) Thanks!

ABait should always be kept out of reach of children, pets and non target animals and has low toxicity to predatory birds. Animals normally have to eat their body weight or more in order to become poisoned. If you do suspect your pet has been poisoned by Terad3, you will need to contact your vet as soon as possible.

Do rats have to ingest more Terad3 to kill than Fastrac or Contrac blox?

QWhat impact does Terad3 have on children if accidententally ingested? Contrac indicates there is a remedy.

AIf Terad3 Blox were ingested we recommend to contact poison control 1-800-222-1222 immediately. Although, it is lower risk product it is still not recommended for ingestion. This is why you always want to place bait blocks in tamper resistant bait stations.

QWill Terad3 kill squirrels that ingest the bait? Also, can squirrels enter the Protecta Rat Station?
We have squirrels on our property and do not want to harm them. Are there any rat bait stations that do not allow squirrel entry?

AYes, it is possible that a smaller squirrel can fit in the Protecta Rat Bait Stations. Since squirrels and rats are similar sized, there are not really any options that will target only rats and not squirrels other than a live catch trap. If you happen to catch the squirrel, you can let it go. It is possible that if they consume the Terad3 bait that it will affect them.
