Terad3 is very effective for rat and rodent control. Rats will not be an overnight fix - so be prepared to be patient, as it can take a few weeks for all of the rats to die off (depending how many you have). Also, when using a bait such as Terad3, you cannot guarantee where the rodent will die. The only way to guarantee where it will die is by using traps. Consider the T-Rex Rat Traps.
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.
The Terad3 Blox should be placed in tamper resistant bait stations within 50 ft of the building. The best way to get rid of the rodents that are already in your cottage is to trap them with snap traps, glue boards and/or live catch traps. We do not recommend using poison baits indoors because after the mice/rats eat the bait they may go into an inaccessible area to die causing a terrible odor and possibly even a secondary insect infestation (it is a myth that there is a poison bait that will cause the mice/rats to dry out and not smell or to leave the house in search of water). It is important that you place the traps directly in the mice/rats travel path and bait them with an attractive bait such as nuts, dog kibble, canned tuna or peanut butter. Be patient, it could take several days or even a couple of weeks before the mice/rats are comfortable enough with the traps to approach them and be captured. After you have eliminated your current infestation, you must take the time to exclude rodents from entering your home in the future.
