What Are Rat Baits

Rat baits are necessary to deal with existing rat infestations as well as to prevent such a situation from happening in the first place. These baits typically consist of ingredients that mimic the scents and flavors of real human food. They also contain lethal poisons of various sorts.

Some rat baits require bait stations, while others can simply be scattered or placed in hard to reach places and highly frequented areas by rats. It is also common to use rat bait products in combination with rodent traps as well.

At any rate, each type of rat bait works in a similar way but takes varying amounts of time to affect the rodents after ingestions. Many baits kill rodents in as little as one day, whereas most baits typically take anywhere from two or three days to as much as a week.

What to Consider Before Buying Rat Baits

Before any significant purchase, it’s crucial to first gather enough essential information to make a well-informed buying decision. That said, we’ve gathered a few of the most important factors to consider before selecting the best rat bait products for you.

Compatibility With Other Bait Stations

Some rat baits are designed with bait station compatibility in mind, others… not so much. Many baits come in chunks that can be broken-down and shaped to fit bait stations regardless if they’re manufactured for compatibility with bait stations or not. That said, a large number of baits are made with circles or indents in them that help lock them in place in certain bait stations (usually of the same brand).

Lifespan of Bait

Another significant aspect that’s easy to overlook is the lifespan of the bait. Not necessarily the lifespan of the poison (which probably lasts for a very long time) but more so of the other ingredients. The length of time which the scent and flavor last are crucial, as they are two of the most important features of the best rat baits. 

Type of Poison Used in Bait

There are several types of poison used in the best rat baits. However, for the most part, there are three types of poison which are used more often than others; anticoagulants, calcium releasers, and acute toxins. 

Each poison works in a similar fashion: the rat ingests bait, the poison takes effect, and then the rat dies from internal bleeding or another lethal effect from the poison. It is also important to mention that acute toxins are considered the least safe of the three main types of poison found in the best rat baits.

Price of Bait

As with most purchases, the price is just as important of a factor as any. Once you’ve narrowed down the selection of rat baits that best suit your needs, compare prices to the benefits and drawbacks of each product before making a final purchasing decision.
