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
How Do Rats Use Pheromones To Communicate?
Releaser Pheromones:
Rats communicate using releaser pheromones to send information to other rats that they are in their own territory. Rats often urinate in areas to send information that they are ready to nurse or that a specific area where their nest is located is their own. Rats use these releaser pheromones to claim territory and to make sure that other rats will stay away.
Primer Pheromones:
Primer pheromones are designed to be excreted during the peak of fertility and this is the type of pheromone that sends sexual signals to males in the area. These scents are released in order to attract males and to make sure that the female is going to mate during a time where she is more than likely to conceive.
Primer pheromones are some of the main types of communication tools used by rats and it's one of the most powerful ones that can be sensed in the area. These responses are triggered by the area of the brain called the Vomeronasal and this refers to the overall sense that an adult male gets of the pheromone.
Information Pheromones:
These types of pheromones are designed to be useful for identifying something about the animals or about the area. Rats often use these to convey fear or to share information about an area. Certain species of rats can share information about a food source, safe space, and more with these types of pheromones. Most of the time informational pheromones are designed to identify the smell of other species and to warn other rats of dangers in the area.
Scientists are continuing to study rats to determine the total number of ways that they are able to communicate by pheromones alone.
