Treatment of<unk>  bites requires keeping the person from being repeatedly bitten, and possible symptomatic use of antihistamines and corticosteroids (either topically or systemically). There however is no evidence that medications improve outcomes, and symptoms usually resolve without treatment in 1–2 weeks. Avoiding repeated bites can be difficult since it usually requires eradicating<unk> s from a home or workplace; eradication is most effective using non-chemical control methods. Non-chemical control methods include vacuuming carpet and furniture (often with scraping) into a disposable bag which is then sealed into a plastic bag to prevent re-infestation. Other methods include removing textile materials from an area and washing them in hot water (at least 60 degrees Celsius) or freezing them at . Most consumer grade freezers are inadequate to kill<unk> s due to not having low enough temperatures. Unremovable textiles such as mattresses can be steamed at least and this method can penetrate deep into the textile to effectively kill<unk> s quickly (under 1 minute). Heating tents or chambers can be used for infested materials or entire rooms can be heated to at least to effectively eradicate infestation. There is no evidence to indicate that a combination of non-chemical methods plus insecticides is more effective than non-chemical methods alone with regards to eradication of<unk>  infestations. Insecticides are mostly ineffective for the eradication of<unk>  infestations as most<unk> s are resistant to insecticides, including pyrethroids which are found in approximately 90% of commercial grade insecticides. Furthermore, insect foggers (known as "bug bombs") are ineffective in the eradication of<unk>  infestation as they are unable to penetrate<unk>  harborages. Resistance to pesticides has increased significantly over time, and there are concerns about harm to health from their use. Once established,<unk> s are extremely difficult to get rid of.<unk> s are particularly difficult to eradicate in apartment complexes as harbors can exist in other areas of the building when single units are treated. Mechanical approaches, such as vacuuming up the insects and heat-treating or wrapping mattresses, are effective. An hour at a temperature of or over, or two hours at less than kills them. This may include a domestic clothes drier for fabric or a commercial steamer.<unk> s and their eggs will die on contact when exposed to surface temperatures above and a steamer can reach well above . A study found 100% mortality rates for<unk> s exposed to temperatures greater than for more than 2 minutes. The study recommended maintaining temperatures of above for more than 20 min to effectively kill all life stages of<unk> s, and because in practice treatment times of 6 to 8 hours are used to account for cracks and indoor clutter. This method is expensive and has caused fires. Starving<unk> s is not effective, as they can survive without eating for 100 to 300 days, depending on temperature. that no truly effective insecticides were available. Insecticides that have historically been found effective include pyrethroids, dichlorvos, and malathion. Resistance to pesticides has increased significantly in recent decades. The carbamate insecticide propoxur is highly toxic to<unk> s, but it has potential toxicity to children exposed to it, and the US Environmental Protection Agency has been reluctant to approve it for indoor use. Boric acid, occasionally applied as a safe indoor insecticide, is not effective against<unk> s because they do not groom.
