Saint Louis County, St. Louis Rat Control Situation:
Hi David! I have a quick question that I'm hoping you can help me with. My husband and I are hearing noises in the attic and we noticed that the outside vent to the dryer has been pulled away from the house. We have some contraction going on in two rooms and after we put Sheetrock up, the next morning a hole was chewed where the ceiling meets the crawl space between the first and second floors. There were also rat droppings on the floor. We went out and bought snap traps (6) and set 2 in the room with the hole, one in the laundry room, 2 in the main attic, and one in the smaller attic above the room. The next morning half the traps were triggered but nothing caught. We reset all the traps and the next morning all the traps were triggered and empty. The rat had also gotten into the pantry during the night and found a bag of dog treats and tried to pull them out under the door. The reset all the traps, wrapping the trigger with gauze and coating it with peanut butter to make it harder for them to just lick it off. For three weeks now the traps have been untouched. We don't have much activity in the attic either. Last night I took some of the dog treats and put it with the peanut butter as added incentive and we finally caught one... A big one. My question is, is it likely that there are more or that we only had the one? We have two dogs inside and it boggles my mind that rats would be ballsy enough to roam the house when there are dogs around! Should I keep the traps out and see what happens or do you think we got it? Only the one trap with the rat was triggered. Thanks so much for your time, Zui in St. Louis MO
My response: If the traps were triggered with no trap, you were definitely using the wrong traps for the animal you were dealing with. So if it was definitely large rat traps that you were using, then you didn't have a rat - maybe an opossum or something. And if it was rat, then you used the wrong traps - did you you mouse traps, by chance?
St. Louis Rat Control Tip of The Week
Will Rats Come Out When It's Light?
Rats are living beings with a negative phototropism. Daylight often affects them, leading them to be most active when it's dark out. Most rodents are characterized by going out during evenings when there is dim light or at night.
This habit of being active at night is very useful when combined with the instinct of going unnoticed. Rats that live in underground places like sewers can suffer retinal damage when they surface in broad daylight. The discomfort to their vision does not allow them to carry out the necessary daily survival activities.
Light is an abiotic environmental factor that can have a major impact on animal behavior and physiology. Rats adapt better to darkness because it can be very comfortable. It is believed that rats have dichromatic color vision and light is often a very important environmental signal for regulating circadian cycles and reproduction cycles.
Fear Of Light Or Fear Of Death?
Rats are one of the most successful invasive species in the world, they can adapt to almost any environment. These animals perceive light as dangerous. The light rays can make rodents feel somewhat exposed to predators or even vulnerable to people who will want to exterminate them no matter what it costs.
A Messy And Damp Place Is Ideal
Abandoned buildings, homes with cracks in the walls, or sewers, often have an abundance of dark places. A home with little light is ideal for living; it is perfect for rats to make their nests without having to expose their small offspring to being eaten by other animals.
Professional exterminators often use this information about the light phobia of rats in their preventive or extermination plans. The ultimate goal is to prevent these rodents from making their dens in or near people's homes.
