Is there any natural or other way of getting rid of bedbugs? Is there any kind of chemical with another purpose that also works to kick out the bedbugs that is available in the market?
I know that there are pest control services available, but they are costly and we have to totally pack the room for at least 12 hours.
Get an exterminator/pest control expert, especially if you are living close to other people. It is not just your problem if your natural remedy doesn't work, it is their problem too. The only effective way to stop an infestation is to attack it as strongly as possible as quickly as possible. This is not something you should try to lifehack your way out of.
I bought a house for a needy family member and it came with free bedbugs. Did a lot of research and ended up using cold and diatomaceous earth. Here is what I found from doing this and reading a ton about it:
Heat, cold, and diatomaceous earth all kill bedbugs.
Cold -- I've successfully rid a home of bedbugs by turning off the water, blowing out the pipes, pouring antifreeze in toilets, tanks, and u-traps, then opening the windows in January to let the house freeze (this in a northern climate). Temperatures in the house hovered between -20F and 40F for two months. Not extremely practical, but nobody was living in the house. And it worked. The infestation was crazy (millions) and this apparently killed the bugs and the eggs. I think the important thing here might be (and this is conjecture) that eggs likely hatched on warmer days, then it would freeze again and kill the starving critters.
Heat -- Close your windows, remove any aerosol cans, gas cans, hydrocarbons, clean out and turn off your fridge, get your food out. Common sense things. Take off your baseboards to allow air to circulate better there. Then heat your house to 60C for a few days, using fans to blow the air around. I've never tried this, but logic says it would work. Problem, there may be leaks to the outside, e.g. in a wall, that keep a space cool and the bugs don't all die. Probably best to get an infrared camera and use that to make sure everything is heated enough. Or, get a pro to do this.
Diatomaceous Earth (DE) -- First, see warnings in comments below. DE is like micro glass shards, and totally natural (shells and remains from dead ocean diatoms - but 'natural' doesn't mean it is safe to breathe). Take off baseboards and remove outlet covers. Sprinkle DE behind baseboards and inside outlets, cracks in floors and walls, and blow under drywall. Use other methods for your bedding because you probably don't want to breathe DE. It kills by bleeding out the poor bastards, poking them so they loose all their moisture. You need to have it around for each hatch, and gotta get enough of it so it kills them before they lay eggs. Hence several weeks.
As you can see, anything other than concentrated chemicals is a PITA.
Tough thing, you probably want to swing the chemical mace. There are mainly two natural ways of getting rid of bed bugs that actually work, but neither one is really easy or straightforward.
So, all in all, chemicals aren't the worst option, really.
Safe fungus wipes out bedbugs from little exposure.
The researchers discovered that they only needed to expose a small percentage of a bedbug population to their new fungal-based biopesticide to achieve nearly 100 percent infection.
Bedbugs exposed to Beauveria bassiana, a natural and indigenous fungus that causes disease in insects, is harmless to humans and doesn't damage furniture. They become infected and die within four to seven days.
The researchers made a company and sell it here.
What did I (with success):
Don't over look the simple solution. We leased an apartment here in Tulsa for almost five years and until we moved out. The cat lady upstairs had bedbugs (and fleas). The bedbugs would occasionally get through the electrical conduit holes from upstairs, arriving in our bathroom. Until then, I didn't even know what a bedbug looked like.
What kept us from getting bedbugs was that we put all our mattresses and box springs in bedbug-proof covers. Then get the bed out from touching any wall, or foreign object. Spray the legs of the bed with bedbug spray. Always make the bed up tightly, so insects have difficulty crawling into the bed clothes.
Three words. BORIC ACID POWDER. Period.
works for small roaches and other insects as well. The powder has long life and is not harmful for humans. Even children. Be sure to spread in the right areas i.e. all around, inside, under beds, electric sockets etc.
Also second natural ways by leaving house to extreme cold temperatures. Usually a warm area problem so this solution will not be applicable most of the times. In warm climates take all furniture, beds, sheets, Clothing and put under direct sunlight during daytime.
You should seek professional help as @llama suggested. However, I just wanted to add another answer with some references I found from UMN and Cornell due to the lack of references in the other answers and my rep is too low to comment.
https://www.bedbugs.umn.edu/bed-bug-control-in-residences - Suggests ways to control bedbugs
https://www.bedbugs.umn.edu/what-not-to-do AND https://nysipm.cornell.edu/whats-bugging-you/bed-bugs/bed-bug-faqs/#15 - These mention various examples of what not to do when an infestation strikes... Like throwing out the mattress since this can cause further contamination or using chemicals when not a trained professional for health reasons.
After talking to my neighbor, I got this insecticides & it's definitely going to work & it costs less than a 1 $dollar.
Name :- Thiamethoxam a.i 25% w/w
Broad Spectrum Insecticide.
Mass:- 5 or 10 gram
Odourless.
Requirement: -
0.5 to 1 L water,
Spray bottle
Close the home at least for 3 hour after spray.
After a week you will spot the difference.
I know one process to get rid of bedbugs but you need to spend some energy. It will take a week but it is very effective. I would call it a natural way.
Everyday make a strong diluted solution of detergent powder (we use surf excel or Ariel here) not detergent liquid after which you have to wash your entire floor with that solution. If not possible then sweep with that solution everyday. Also make a strong concentrated solution of detergent powder and pour it in a liquid sprayer bottle. Evenly spray it in infested area everyday.
A slight contact with this solution instantly kills the bedbug and even its eggs become sterile.
The detergent powder solution is alkaline. But I never understood why they were killed?
I covered the lot in anti bed bug powder that I found in the shop, not sure what it was made off, but I also wrapped all my mattresses and pillows in clingfilm for a couple of months, also covering them in the powder.
Also used celo gel, the stuff you find in new shoes, on the floor under the bed mixed with the powder.
And used a spray of places like keyboards etc.
All that seemed to work, but I lived in a small flat and caught infestation early.
You can kill bedbugs with heat, but using your thermostat or a space heater won't do the job. Special equipment and very high temperatures are necessary for successful heat treatment(47-50 degrees Celsius). If it's hot enough outside, belongings can be put in black plastic bags and left out in the sun for several hours.
Bed bugs can also be killed by exposing them to freezing temperatures for 12-24 hours.
If you want to keep your mattress cover it with a mattress encasement. While it could take up to a year, the bedbugs living inside of the mattress will eventually starve to death.
Funny thing no one will vote this answer up but this is the only answer that works (worked for me).
You could keep popping them spraying them even heating the whole room up will not help kill them all and a few will survive anyways.
You could try killing these bedbugs for years but every couple of days they will replenish back to numbers again.
Anyways the only way to get rid of them is to throw the mattresses out, that's like throwing out their lifesource that puts them into a depression and you have to move living in a uninhabitable room (living room) they wont walk from one room to the other because they will be in a depression and just die out from hunger after a year or so and you could move back in there.
