Top 5 Best Mouse Poisons To Buy (**2020 Review**)

Of all the mouse poisons we researched and reviewed, our top pick goes to Contrac Blox.

Why?

In large part because of personal experience we've had using it ourselves.  Also, it has an industry proven track record of success.  The active ingredient, bromadiolone at 0.005%, delivers a lethal dose in only a single feeding.

It can be used inside and outside, has a long lifespan, and has good weather resistance.

The active ingredient in Contrac, from Bell Labs, is bromadiolone at 0.005%, making it a single feed rodenticide.  It kills Warfarin resistant mice and rats.  It is weather resistant so it can be used inside and out.

The blocks are created with a hold in the middle so they can be mounted on slender rods inside bait boxes.  This will keep rats and mice from trying to drag the bait back to their lair.

Change the bait every 40-60 days in the winter if it hasn't been eaten. During the hot summer months, you'll need to change it more often.  It comes in an 18-lb bucket, so don't be hesitate to use it.

​

Also from Bell Labs, the active ingredient in Final Blox is brodifacoum at 0.005% so it's a single feeding rodenticide that will kill mice after only one little nibble.  It's slightly less expensive than our top pick, but a little bit slower too.

Always use it in conjunction with bait boxes to keep children and pets from eating it.  It can be used inside or outside.

This bait is weather resistant.  You only need to change it every 40-60 days or so.  During hot weather, or in the summer, you will need to change it more often.

Neogen created this pelletized rodenticide for multi purpose indoor and outdoor use. Their all weather composition makes them a versatile option for your rodent problem.

Many customer reported the mice loving taking these pellets and storing for later. So it may take a while before the mice ingest these pellets, meaning results may not occur for a week or more.

These are extremely easy to use; just toss them into an attic, closet, tool shed, or any other enclosed area where children and pets can't get to them and your job is done. 

These paper encased place packs, from Farnan, come 5 to a package for those times when you only need a small amount of rodenticide and don't want to spend $80-$90 on a bucket of bait.  

The active ingredient is bromadiolone at 0.005%, so it's a strong, single feeding bait.  It can easily be used in attics, basements, crawl spaces, tool sheds, well houses, and other enclosed areas where children and pets can reach the packets.

It has good weather resistance and will last for a good couple of months before you need to replace it.

These peanut butter flavored bait blocks, from J.T. Eaton, use diphacinone at 5% as the active ingredient.  This is a multiple feed bait so it will take longer to eliminate mice and rats, but it is significantly less expensive, so it's a good trade-off.  

The peanut butter flavor is a nice touch since that's a food mice and rats have a known fondness for.

It has good weather resistance, and like all bait blocks, should be used with a bait box to prevent children and pets from gaining access to it.

(If we sound like a broken record on the pets and children issue, it's because it's so important.)

In cool dry weather, the bait will last for up to 60 days.  In hot or wet weather, it will have to be changed more often.
