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
Dealing With A Rat Infestation In Your Attic
Black Rats are small rodents that are common in almost all areas across the United States, and because of their smaller size they are considered to be less of a threat and a pest than Norway rats, their larger cousins. However, rats also carry a range of different diseases and can also pose a health risk to you and your family, so if you do find an infestation, it is worth dealing with is promptly. Rats are also good climbers, so finding them nesting in your attic is not uncommon.
Identifying That You Are Dealing With Rats Rather Than Other Pest Animal Species
The first step to dealing with an infestation is to ensure you are dealing with rats, as the sounds of scratching from the attic can sometimes be other animals such as rats, squirrels or even raccoons. The best way of identifying that it is rats you are dealing with is to check on any rat feces that you can find. These small pellets of poop should be significantly smaller than rat droppings, and will be around the size of a small grain of rice, and is black when fresh, turning brown and then grey after some time.
Precautions Before Carrying Out Rat Control Work
Going into a confined space where pest animals are present can be dangerous as there are often diseases that can be transmitted by rats. Wearing long sleeved clothing and gloves will help protect you from any nips from animals and also prevent direct contact with feces of urine. Another smart precaution is also to wear goggles and a breathing mask, as some diseases transmitted by rats can become airborne, and can then prove to be a dangerous problem if those airborne particles are then inhaled.
Laying Traps To Catch Rats
By far the most common and affordable way of dealing with a rat infestation in the attic is to lay traps to catch the little animals. The standard snap traps on a wooden base are cheap to buy and just as effective as more expensive options, and can be re-used, which is particularly useful if you have a larger rat infestation to deal with. When laying traps in the attic, make sure to lay them near the areas where you see the greatest buildup of rat feces, and also near any entry points they may be using to get in and out.
Removing Carcasses And Monitoring The Rat Problem
Once you have laid the traps, the next step is to monitor all of the traps over the next few days, to see how effective the traps are at dealing with the problem. With any rat carcass, you can simply bag it and place it in the garbage, or it can also be incinerated as well if you have the facility. Keep re-setting the traps and continue to monitor until you are no longer seeing any signs of rat activity and you are no longer catching any rats in your traps.
Repairs Required After A Rat Infestation
The key step to take after catching and dealing with all of the rats is to seal the attic, as they will often have several entry points to help them get in and out of the area. These should all be sealed using metal flashing or a suitable filler to prevent other rats from being able to get back into the area again. You should also try to remove any feces that you can, and if insulation is heavily soiled then that should also be replaced. One wise precaution is also to fumigate the attic after your repairs, to kill off any remaining bacteria or other particles that could be harmful to anyone going into the attic in the future.
