Some oils like tea tree and neem oil can't kill bedbugs, but they work well to repel them. Tea tree oil is an extract from the Melaleuca alternifolia plant—it can cause various health problems with pet birds, cats, and small dogs. If there are pets in the house, look for other safer choices. If you use the oil, apply it in small quantities to the skin to repel bed bugs. Since bed bugs are active at night, apply it before bedtime.
It is also recommended to put infested items, such as a mattress, in a sauna that reaches temperatures of upwards of 170° Fahrenheit. Similarly, they also perish in extremely cold temperatures so mattresses and other items can be cleansed of these bugs with the use of plastic wrap and dry ice. Cover the items with large plastic tarps and carefully insert dry ice, and then secure. The extreme temperature will naturally fumigate the pests.
Kept replacing the sticky traps just in case but never caught anything other than the occasional spider. Always cycled the sheets and such using the car+sun. They were still getting to us. Bed bugs cannot fly or jump. They had to be in the bed frame. I check it over and notice rusty spotting, which is apparently bed bug fecal matter. Luckily ours was from IKEA so it was easy to take apart – and sure enough – there they were. The way my bed works is a metal frame with holes, rubber end caps fit into those holes, and wooden slats run across the frame in the end caps. So every few days I’d mix up a 50/50 mix of bleach and water in a bucket and soak the wooden slats and end caps for ten minutes. The bed bugs were gone a couple of weeks and came back. I started soaking the things longer and scraping them with a disposable spoon, which was hard to do on the end caps. It warped the wood a little but nothing too bad. After a couple of weeks or so, I stopped finding bed bugs in the frame. I was worried they were in the metal too, but I completely stopped getting bites. I think the added time and scraping got rid of eggs. Not a lot can survive a 30 minute bleach bath.
Heat Treatment – this method kills bed bugs with heat. This could be implemented on clothes by putting them in a drier at a high temperature for 30 minutes. In a room, the use of heating devices could kill even the eggs and the nymphs of bed bugs at certain levels temperature at different durations of time. Ideally, to kill bed bugs in all stages, the temperature must be 115 degrees F or 46 degrees C.
Bedbug infestations seem to be increasing around the world at an alarming rate, possibly due to insecticide resistance. [1] Resistance to pyrethroid insecticides is already widespread in the United States. The bedbug occurs in aggregations when conditions are favorable, but the arthropods disperse when conditions are unfavorable. [2] Active female dispersal can potentially lead to treatment failures and should be taken into account when using control methods.

Bedbugs often invade new areas after being carried there by clothing, luggage, furniture or bedding. The creatures don't discriminate between dirty and clean homes, which means even luxury hotels can be susceptible to bedbugs. The most at-risk places tend to be crowded lodgings with high occupant turnover, such as dormitories, apartment complexes, hotels and homeless shelters.

First up are the contact sprays, like STERI-FAB and JT Eaton Kills Bed Bugs. These will kill quickly, but evaporate shortly after, leaving no long-lasting protection. Spray along baseboards, below drawers and on drawer slides, behind cabinets, and behind night stands. Follow up with a residual spray, such as Bedlam Plus and JT Eaton Kills Bed Bugs Plus. Residual sprays will offer long-lasting protection against bed bugs and hatchlings. Bedlam Plus is ideal for cracks and crevices throughout the room, while JT Eaton Plus can be used below the cushions and bases of sofas, chairs, edges of carpets and other fabric items.
Bed bugs could be hiding in all sorts of tight spaces in your room, like wood cracks, inside books and furniture, and along the baseboards and the edges of the carpet. In this step, we’re going to clean, vacuum, and steam those areas that bed bugs are likely to be. This will cut down on the bed bug population while making it harder for survivors to hide.

Bedbugs may enter your home undetected through luggage, clothing, used beds and couches, and other items. Their flattened bodies make it possible for them to fit into tiny spaces, about the width of a credit card. Bedbugs do not have nests like ants or bees, but tend to live in groups in hiding places. Their initial hiding places are typically in mattresses, box springs, bed frames, and headboards where they have easy access to people to bite in the night.

Cracks and crevices of bed frames should also be examined, especially if the frame is wood. (Bed bugs have an affinity for wood and fabric more so than metal or plastic.) Wooden support slats, if present, should be removed and examined since bed bugs often congregate where the ends rest on the frame. Screw holes, knots and other recesses are also common hiding places. Headboards secured to walls should be removed and inspected. In hotels, the area behind the headboard is often the first place that bed bugs become established. Bed bugs also frequently hide within items stored under beds. 
^{We are often asked, "How do you kill bed bugs?" While we would love to give a simple answer, this is actually a loaded question. There are many ways to kill a bed bug but, if you want to kill all of the bed bugs in your home or business, it is important to pay attention to the details. Here are some ways you can kill bed bugs, and what you should know about each.}
With the bed now fully isolated and elevated, bed bugs hiding elsewhere in the room won’t be able to feed on you or hide in your bed. You can also use the ClimbUps to monitor the changing population of bed bugs in your home. Hopefully, you will see less and less bugs appear in the traps as you go through the next steps. Now that you have created a safe haven in your bed, you can move on to treating the rest of the room.
