For rats: Apply 2 to 8 packs (1 to 2oz) of First Strike Bait per placement. Rat baiting placement varies by location. Generally placements are 15 to 20 feet apart as rats will travel quite some distance in search of food. You must maintain a constant supply of bait for 10 days for best results.

Replace consumed bait immediately to keep a constant supply.

To prevent re-infestation you must limit alternate food sources and seal entry points.

Time to Kill

First Strike Soft Bait takes 4 to 5 days to kill rats and mice after they eat it. Bromadiolone is a slow acting poison that prevents and overcomes bait shyness.

When using a bait box, should I empty the packet contents into the box or leave it in the pouch? If the pouch is untouched should it be replaced after some amount of time, and what is that amount of time?

Thanks for your help.
j on Feb 1, 2017
BEST ANSWER: You can leave it in the pouch or empty some in the trays, either way the rodents will get access to the bait. Small amount in trays, with stations staked well, will reduce lost bait and the chances of accidental poisoning. Replace after you start seeing mold, or insect activity. Not set time, depends on area, moisture, etc.

Will it harm my cat if he finds a mouse with the poison residue on the mouse's mouth/fur? How long is the poison effective? I'm wondering how long I need to worry about my cat finding dead mice (6 months, 3 years,??). Thanks
Jeff on May 13, 2016
BEST ANSWER: Firststrike does have a risk of secondary poison, you would need to try and locate any of the dead mice in the area, and dispose of them. The good thing is that cats do not usually like to eat dead mice.

But there still needs to be a certain amount of precaution.

This stuff just works
We live outside of Phoenix on 10 acres and have more than our share of critters, mostly pack rats. First strike is the way to go. As long as you keep the bait stations baited for a couple of weeks the problem is gone.

This is the best product that I have ever used and it works immediately! You have to make sure you check the stations and add fresh bait. No mice! I will forever be a customer. I have told everyone about this product.

This rodenticide was recommended by the Washington DC office of rodent control. It works perfectly in burrows and traps.
