Rats are some of the most difficult creatures to exterminate and nearly impossible to control unless you are a trained and experienced technician or licensed exterminator. Rats are the cause of billions of dollars in damage globally and billions in lost food stores that get infested with rats. The UN considers rats a primary threat to human life and the New York City government funds and regulates a Rat Task Force that can be called out when rats cause severe issues. They will travel around the city baiting sewers and public buildings with powerful poisons in the hopes of stemming the tide. Rats are considered a pandemic in the western world and dealing with them safely and humanely may have the reverse effect you anticipate.
If you are dealing with a cockroach infestation or have suspicions thereof, contact Rat Pest Control for a fast and effective complete eradication.
Commercial processes for rats are not humane and can be dangerous when improperly placed. A technician who is hired to deal with your rat issue will come to your property and perform an exterior inspection of the house as his first step in his pest control plan. He will be looking for entryways rats could use to get inside. If the technician thinks you have a lot of rats in the house he may leave one entrance open and attach to it a one-way door that allows the rats to safely vacate the house only to find they have been locked out. This process is the safest and will be very effective in getting rats out of your home, it is completely safe and nothing from a pet to a child could be harmed by exclusion.
That being said, the rest of the treatment, the internal treatment if you have ratted on the inside of your home and the general exterior treatment. It is important to know that if you have rats on the inside of your house you will also have them on the outside, this is how rats function when invading a house. They live outside and hunt in the house. So the One-way door can be very effective in getting them out without killing them but they will still be living in your yard. To resolve this a bait station must be placed with powerful, commercial-grade bait called rodenticide. This chemical is a poison that limits vitamin k production, which is an important vitamin for life. This causes internal bleeding and dehydration and kills the rat over a period of two to seven days. This is highly affected but the rats tend to leave crumbs of the poison coated crackers around the bait station and if your dog eats enough bait, which would be a lot, likely more than you would have on your property the dog would experience the symptoms of rodenticide poisoning, which is sluggishness and dehydration. To resolve it you would take the animal or child that ate the bate to the doctor or vet and they would get a large direct injection of vitamin k which entirely reverses the effect. This was an intentional choice in the design of the poison to make it safe for home use.
