Per the First Strike Soft Bait Rodenticide label, for humans or animals ingesting bait and/or showing obvious poisoning symptoms (bleeding or prolonged prothrombin times), give Vitamin K1 intramuscularly or orally.
We are unaware of any changes in the label for the First Strike Soft Bait Rodenticide. Our records show that the last updated information for the label and SDS was July 2016.
The active ingredient Difethialone in First Strike Soft Bait Rodenticide is classified as highly toxic by oral consumption. It is a single feed anticoagulant that stops blood clotting, and one day’s feeding can deliver a lethal and toxic dose. You can view more details on the SDS here.
As far as kill time, the manufacturer reminds us that First Strike is an anticoagulant, so it is designed for continuous feeding. A rodent will get a lethal dose (approximately 4 grams is a lethal dose) on Day 1 but anticoagulants are designed for a rodent to feed day 1, day 2, and day 3 before mortality. If the rodent only eats First Strike on day 1 and no other day, then 50% of the product is out of its system on day 2. There are variables that would play a role in this situation.
If your question is in reference to secondary poisoning, please remember that the probability of it with an anticoagulant is extremely unlikely. A rat can consume 20-25 grams of bait in a day, a mouse 5-10 grams. The rat or mouse will die in approximately 3-5 days, during which time it will have excreted up to 50% of the active ingredient. Keep in mind as well that most pets will play with the dead rodent rather than eat it, but if they do, it will take a large quantity of dead rodents to be lethal, depending on the animal's weight. Please remember that the dead rodents should be picked up and disposed of, preferably daily. The probability of getting a disease from a dead or dying rodents probably exceeds the likelihood of getting sick from any residual active ingredient in the baits.

While First Strike Soft Bait Rodenticide could potentially kill pack rats (woodrats) if they ingested it, this bait is only labeled for use against Norway Rats, Roof Rats, and house mice. A great bait for woodrats which can also be used for burrow baiting is Contrac Bulk Pellets. Be sure to follow the label directions for safe and effective use.
If First Strike Soft Bait Rodenticide or any other rodenticide is used improperly, then it can be hazardous to both humans and animals.

TREATMENT FOR PET POISONING: If animal eats bait, call veterinarian at once.
NOTE TO PHYSICIAN OR VETERINARIAN: Contains the anticoagulant difethialone. If swallowed, this material may reduce the clotting ability of blood and cause bleeding. For humans or animals ingesting bait and/or showing obvious poisoning symptoms (bleeding or prolonged prothrombin times), give Vitamin K1 intramuscularly or orally. Also for pets, if needed, check prothrombin time every 3 days until values return to normal (up to 30 days). In severe cases, blood transfusions may be needed.
First Strike Soft Bait Rodenticide is a highly palatable bait second generation anit-coagulant, and will be preferred even when other food sources are available. You should use 1-4 pouches per placement usually spaced 8-12 feet apart. You should start to notice results in about 4-5 days. It can take multiple feedings over that time period for the bait to take effect.
First Strike Soft Bait Rodenticide is a second generation anticoagulant bait. So it works on the clotting agents in their blood and causes them to internally bleed to death after ingestion. It can take 3 - 5 days for it to completely take effect.
The SDS for First Strike Soft Bait Rodenticide states the LD50 (oral-rat): >2000 mg per kg. Time kill depends on how big the rat is and how much they ate but can range from 1- 5 days after consuming a lethal dose.
In most cases, secondary poisoning is not going to be a problem unless the predatory animal eats many rodents that have succumbed to the effects of the First Strike Soft Bait Rodenticide. The exact amount of mice that must be eaten for the predatory animal to become sick will depend on the size and the health of the animal but usually they would need to consume near their own body weight of bait to get sick. We do recommend that you contact your vet if your dog is sick or shows signs that are abnormal. Please provide the vet with the MSDS for more information.
First Strike Soft Bait Rodenticide is a 2nd generation anticoagulant rodenticide meaning that rodents are affected or killed after a single feeding of bait.
For mice: Apply 1 pack per placement, usually 8 to 12 feet apart. Up to four packs may be needed at points of very high mouse activity. Maintain a constant supply of fresh bait for 15 days or until signs of mouse activity decrease.
For rats: Apply 12 to 48 packs per placement, usually spaced 15 to 30 feet apart. Maintain a constant supply of fresh bait for 10 days or until signs of rat activity decrease.
Each soft pack placement of First Stike Soft Bait Rodenticide is 10g, so there are approximately 726 pouches per 16 lb pail.
