I need to know what kind because of the research I have done. I was hoping for a wood rat because they usually only have 3-4 litters per year and breed when it is warm out. Also the wood rat, from what I am told, infests in 2's or 4's. The Norway rat is an exceptionally hard one to get rid of because they breed every 1-2 months and can have as many as 14 in a litter averaging 8. Also, the Norway rat borrows in the ground under foundations and such so they are hard to find because they are mainly nocturnal. The research and the pest control people I have talked to also say the Norway rat is one of the hardest to try and trap because they seem to be the smartest and shy of new things.
So far 3 days of game cam and traps and nothing within the house. Now I will have to worry about my out buildings. I have 5. 1 is a newer pole barn with a dirt floor, 1 is a grain storing quanset that locks up tight, and the others are just old chicken coop looking buildings. Since they are Norway rats they have a den somewhere that I need to find and get rid of.
The cat idea is going to be a reality because I have 2 spoiled piggy cats in the house that won't even kill mice anymore, used to have outside cats but had to get rid of them...since then bammm there comes a rat. Gonna pick up a couple barn cats this weekend.
Rats suck!
