Inspection

Inspecting your house or area where you think you might have an infestation is the first and most crucial step. The inspection will help you to find both, the places where rats might be hiding and the places through which rats might be entering your home. During the process, you might come across areas which need your immediate attention or places that need a quick fix. You might find some unsealed cracks and holes or any area that must not be left unattended.

Play a little game of hiding and seek and find out where the population is hiding. Think about all the possible areas where rats could be housing. Lofts and attics, walls, kitchen, basement, cellar, sheds, garage or maybe backyard, make sure to go through these areas. Attics are dark places which are commonly empty and turn out to be an ideal place for nocturnal rats to reside. Attics contain cables, cardboard boxes, insulation, which are the best places for rats to build nests in. moving up and down the building is made easy for rats, by pipes along walls. They get access through small gaps and scamper through pipes. Basement, where you usually store food, drink, and other important stuff is not safe from rats either. These dark dank areas often become nest to many rats providing them with easily accessible food, warm well protected shelter and easy entry points to move in and out. Kitchen and laundries have electrical appliances like washer machine, dishwasher, microwaves which provide warm places to hide. Outside your house, in garage and sheds, rats like to build nests there because they are well protected and full of equipment. In the garden, there are large shrubs, woodpile, trash cans and birdfeeder which basically have all the supplies including shelter, food, and water that rats need to live, thrive and start a family and soon a colony.

Rat-Proof Your House

Next step is to rat-proof your house. Before getting rid of rats once and for all, it is imperative to not leave your home vulnerable to rats again. Taking steps to make your home rat proof will prevent re-infestation. Without getting rid of factors that allow easy entry of rats, all your hard work will go to waste. There is no point in buying expensive poisons and traps, and putting so much efforts to place them around home only get re-infested later by rats again.

First and foremost, close all holes and seal all gaps bigger than a ¼ inch. All vents and gaps in attics should be sealed at once, also attend to gaps under window sills to make no entry points are left open. All the pipes which provide outside water supplies should be sealed. Don’t leave your woodpile anywhere around your house and cover your chimney to stop rats climbing up and down. Don’t leave your lawns unkempt, maintain your garden by cutting grass time to time so you can see rats lurking around. Get rid of any long shrubs or that might bridge to your house, any shrub or plant too close to your house will allow rats to dig under the foundations. Use natural repellents like garlic, bay leaves peppermint oil and onions to deter rats from entering your property and getting rid of the smell from the previous infestation.

Using Humane Traps to Get Rid of Rats

Traps work best when you know the location where the population of rats is hiding. You can set traps around rat infested areas and lure them out using bait. Traps are useful in a way that you don’t end up with stinking dead bodies of rats lying around your house. humane live traps allow you to capture living rat whom you can transport to a different place far away from your home. It is a good method to get rid of rats without actually killing them, but if you have a serious infestation, this method will cost you a great deal of time and effort.

Using Killer Traps to Get Rid of Rats

Traps are great alternatives to poison as they are not toxic and safe to work with. For decades they are being used as an effective form of rat control. Like humane traps, snap traps to require a great deal of patience and efforts, but the hard work certainly pays off.  These traps are not for the weak heart, if you cannot stand the sight of dead rats with their skull snapped in a trap, then this is surely not your cup of tea. Be careful when disposing of those dead bodies though.

There are different types of traps out there in a market. we will talk about a few of those, including snap traps, glue traps, electronic traps and gas traps. Which trap to use depends on how severe the infestation is and what type of rat is infesting your house.

Snap Traps

snap traps are very popular because they offer quick result in cheap price and can be used multiple times. When you think about snap traps, the trap which probably comes to mind is the one we see on television and cartoons, a wooden block with metal trigger and piece of cheese attached as a bait. The real-life snap traps work in a similar way, by luring a rat to wood or plastic surface by a bait which is attached to a trigger. Rat is killed instantly, the moment it charges forward to take a bite of that bait. All this might sound easy, but it is tedious and creates a hell of a mess. The trick is, to set up the trap in the right place under constant supervision. Snap traps are not suitable for households where there are children or pets.

I say it in every article…we use Victor snap traps 97% of the time.

Electronic Traps

Electronic traps resemble cages without a door to capture rats. These traps instantly kill rats in a more humane way than a snap trap. Once the animal gets inside the trap, it delivers a powerful electric shock to the rat which results in killing rats at the spot, instantly. Before you buy any electronic trap, make sure you buy a good quality trap, some traps deliver weaker electric shock than it is advertised which doesn’t kill bigger and stronger rats. This will result in a slow and agonizing death of rats. Disposing of the dead bodies is also less messy and less troublesome.

You have many to choose from; “The Rat Zapper” is the originator and is the choice for this professional.

Glue Traps

Glue traps are cruelest of all traps as they make sure that the rat dies a slow, agonizingly painful death. They are basically just a leather strap, wood or plastic surface covered with a thick layer of glue. Since rats have poor eyesight, they can’t really differentiate and think of the adhesive coat as an extension of the floor. Bait is placed in the middle of the adhesive when rat treads carefully on it to get the bait, its paws will get stuck to the glue. The strong adhesive will hold on to the rat for as long as you either show up to dispose of the rat, or it dies from dehydration if left there for a long time. In some cases, rats will rip their flesh or limbs off to get free or, suffocate themselves by getting their nose stuck into the glue. In either case, it is not a pleasant sight to see, so we suggest that you use the trap which you find convenient and effective.

Regardless, there are occasions when glue boards are of best use. A pro tip is that oil breaks down the glue so if have an animal on a trap…or a child steps in it simply put some vegetable or olive oil on the glue board and the glue will dissolve.

Setting Up A Rat Trap

First, use Victor rat traps. Some of the most common mistakes people make when setting up rat traps are, placing the traps at wrong places, leaving the traps unmonitored and not placing enough traps. Using Rat traps is all about finding the right location. Before setting up a trap, it’s wise to carefully look for areas where rat activity has been observed, locate their nests and feeding location. Place your baited traps on the travel routes of rats or else you will not be able to catch any rat at all. You can easily determine their location by inspecting every area and look for any rat droppings, claw marks or grease marks. If you find any of those, this is where you need to set up a rat trap.  If you don’t want to go through all the trouble of locating rat spaces, buy many traps and just place them everywhere. Rats are clever, they don’t wander around carelessly. They will go out of their way to avoid a dangerous situation. First, gain their trust by letting them feed off the bait in a trap, this will instill courage in them and guarantee a second visit. Next time the rat will let its guard down and approach the bait confidently.

With so many rat eradicating solutions out there such as trapping, poisoning, baiting, and shooting – trapping stands alone as one of the safest, cheapest and quickest method of all. We shall talk about some pros and cons of using rat traps that might need your consideration.

pros: Trapping is a safer way to get rid of rats as compared to poisoning which might be risky for children and pats. Rats traps are more effective and give quick results for smaller rat infestations. It is easy to locate and dispose of off dead rats before it gets too stinky and smelly.

Cons: Unfortunately, for large and severe infestations, rat traps may not be very effective. It can be extremely tedious, laborious and time-consuming.  While traps may be safer than poison, they are not much safe for children – especially snap traps. These types of traps close shut with serious force, that’s great when killing a rat but not so great if a child or pet happens upon a trap. It is encouraged to use rat traps inside secure bait stations, to safely trap and easily dispose of the dead body. Some glue traps are not considered humane because of their ineffectiveness which can result in the slow and painful death of a rat. Moving a dead rat with glue trap attached is a sight not suitable for faint hearted people.

Tips for Trapping Rats

Number one rule of rat trapping is to place traps in the right places. For more effective results, place the traps hidden along paths where rats are most likely to travel. Place traps in closet, under furniture – such as sofa, tables, chairs or even cabinets and under floorboards.

If you are using rat traps to get rid of rats, you might need plenty of traps to place everywhere. The top principle of utilizing any rat trap is to use many traps. You may require more traps than the size of the population infesting your house. Usually, people underestimate their number and end up buying fewer traps which are insufficient for trapping the whole population.

Know the difference between rat traps and mouse traps, and make sure you always buy rat traps because n average mouse trap is never enough to catch a notorious rat.

Inspect the area before placing a trap. Set up traps in areas where you have observed rat signs such as droppings, grease marks or scratch marks. These signs will confirm rat activity in the area.

Place traps 15 – 20 feet apart since rats like to touch surfaces as they move, place the traps accordingly.  It would be a good idea to place traps touching a wall.

Use the best bait in your traps according to the diet of the rat. Keep in mind the species you are dealing with, because different species of rats eat different food. Black rats are herbivorous while brown rats are omnivorous in nature. Regardless of whatever species of rats, use bait with a strong smell to lure rats into traps.

Set snap traps in such a way that their trigger end is almost touching the wall by setting them extended at a right angle from a wall. You can set traps in pairs as well in such a way that triggers situated on either side to intercept rats.

Don’t set up all traps in one day and expect to see the results the next day. Rats very clever and cautious creatures, some rats are shy to explore new places or objects. Place unset traps in new and different locations for week or two will increase the chances of catching rats.

Allow rats to feed off the unset trap for a day or two. The critters will get accustomed to this safe trap and accept it as part of their regular turf. Bait the trap next time and set it up to snap a rat.

Some rats are trap shy, no matter what you do they will not get in the trap. You can trap these rats all in one night by simply selecting an area where you will be putting your bait such as a pile of grains, bark, sawdust or any other natural area where rats assemble.  Bait large number of unset traps with nuts or peanut butter. You can either hide the traps in a cardboard or pie pan – or you can just leave the traps in the area. Rats will soon start discovering the traps and feeding off the bait, they will start to get used to of the traps and baits. Set up a large number of traps enough to kill a large population of rats before they become shy of traps. This method is called “mass trapping” and it will kill rats en masse and seriously get rid of the population before they even repopulate. You might have to repeat the process again depending upon the infestation.

Different places require a different number of traps. Place the traps according to the need of each area, for instance, trash room may require as many as 1 – 2 dozen traps while the living room may require as few as 3 – 4 traps.

If you still have infestation left even after mass trapping, it means you are dealing with the wisest and cleverest of rats. They have alpha rats and beta rats in their population. Beta rats get caught in snap traps easily, but alpha rats are not an easy catch.  They are very cautious around traps and know very well how to avoid them. to get rid of alpha rats you can either use live traps or rodenticides. Poisonous rat baits are also very effective as they kill rats instantly.

Stop the rats outside your house before they even get inside. Placing snap traps outside along the fences and trellises will prevent rats from getting into your property any further.

Do not ever touch rat traps with bare hands. Always wear gloves when handling traps and baits. Rats can detect the human smell, if you touch the trap with your bare hands, rats will know the human involvement, and will stay away from the trap.

To catch a rat in trap successfully, place a small bait in the center of the trap. Always use a moist bait which won’t dry up and fall off easily. If you place a dangling piece of meat, a rat could easily pry away the bait, set off the trap and enjoy its treat somewhere far away from the trap.

Wash your hands before handling the traps, make sure you haven’t touched any animal before touching the trap with bare hands.

Always use gloves when dealing with rat traps and rat corpse, to reduce the chances of contacting ectoparasites or diseases causing organisms.
