Chin up, you can do it! It's gonna take a while though, you can't give up.
FIRST THING: Eco-Raider or Eco-venger are non-toxic sprays that are going to be your best friend. Don't wait for the landlord or exterminator, get on it and buy it. Sounds like you need at least a gallon or 3. You don't want to run out, this is a long road. You need to spray it every day around where ever you or other people in the house are, including your bed, furniture and shoes that you wear. You need to seal off your body with clothes when you are at home, no bare feet. You can spray it in the corners if you want, but the advantage of that product is that it's non-toxic. It says there's a 10-day residual effect, but I spray it almost every day. You need to completely stop them from feeding on you so they die off before they can get to the next life cycle and breed. A lot of times you can't see the bites or feel them if they are from baby bedbugs which is a problem because they are advancing to the next stages of life without you knowing. Just assume they are there even if you don't get bites for awhile. Seeing adult bedbugs? Musky smell in bed? All a sign of a bigger infestation. Don't worry about coordinating with your landlord, just get on it. DO NOT WAIT A WEEK TO DO ANYTHING. More hardcore chemical poison like Harris Bedbug Killer (least poisonous of the poisons) are better for the corners, and edges of your home, you need to vacate your house until that stuff dries, read the label. If you sit on furniture, like recliners or couches for a long time, put interceptor cups on them too and keep your feet off the ground or spray all around your floor and feet with Eco-raider.
Cimexa or DE in interceptors? Yes.Encasement ripping? Yes, it will. You can buy or rent a steamer and steam the crap out of your bed and furniture. Links below. Bed should be about a foot and a half away from the wall. Don't let blankets or pillows touch the floor.
Encasements aren't good when your infestation is bad, because it will trap them in there for a while until it rips, and then they are more hungry from starving inside.Pets: They do bite pets. My idea would be to saturate a small rag to make a repelling fumigant with Eco Raider and tie it to their collar or feet. I don't know if this is safe, you should call a vet and check or the call the Eco-raider phone number. Cats are more delicate.
Skip the Heat treatment of all types, a waste of money, very expensive, landlords probably won't pay for that anyway. I didn't get one because I have too many musical instruments, it melts everything like pictures. They tell you to get everything like that out of the house, what's the point of that, if there are bedbugs in there?
Get exterminators to use your products? No.
FUMIGANTS: You can also saturate a washrag or piece of fabric with Eco-Raider and use it as a FUMIGANT (Repelling agent) by putting it in with things you bag up that you can’t or don’t want to wash. Stuff needs to stay bagged up about two weeks. Use heavy duty contractor bags and keep duct tape or painters tape around to seal up any holes.
FUMIGANT, DIY: You can make Fumigants that repel by saturating fabric or cotton balls with TeaTree Oil, Clove Oil and Oregano Oil. You can use water or alcohol to "extend" it (water it down) and put in a spray bottle. Put the soaked fabric in little pill bottles with the top open in place you want to chase or keep them out of like closets
Eco-Raider: The product you will use most. Get some smaller bottles to refill too.
Smaller Bottles:
