To reduce the effects of swelling and rashes, you could take an over-the-counter antihistamine, which is usually in the form of an oral pill. Be sure to check the product label for possible side effects, though: some may cause drowsiness, dizziness, irritability, and vision changes, ringing in the ears, and other disrupting symptoms. You’ll want to be careful about taking these pills if you’re going to be driving or operating heavy machinery, and you definitely want to talk to your doctor first if you’re pregnant or have high blood pressure.
In the case of beds, a more economical option is to encase both the mattress and box spring in a protective cover like those used for allergy relief. Encasements specifically designed to help protect against bed bugs are available through retail or pest control firms. Higher quality ones tend to be more durable and comfortable to sleep on. Once the encasement is installed and zipped shut, any bugs which happen to be inside are entombed and eventually will die. Encasements also help protect newly purchased beds, and make it easier to spot and destroy any bugs residing on the outer surface during subsequent examination. Encasements will not, however, keep bed bugs from crawling onto a bed and biting a sleeping person.
I have been divorced from my ex for 4 yrs now but remain friends with him and see him often. I recently learned that my ex in laws have a heavy bed bug infestation. My ex lives 3 houses away but is at his mothers every day as they are elderly. He has been dealing with the bugs and my ex’s petulance about the bugs. They have doctors appointments coming up and I wonder if they should tell the doctor about this. My ex has tried to get them to bathe more, treat the bites, wash the clothes but they act as if it is a big imposition to them. I have not asked him over since I found out about them and am reluctant to do so. Am I wrong in thinking that the ex in laws can spread them to others at the doctors office and is it possible for my ex to bring them here?
If you know that you have the bugs. Get sealing covers the kind that encloses completely, one for the mattress and one for the box spring. That will trap those critters inside and they will eventually die in there. Next you will need to decide of what combination of treatments you wish to use. Its a job that you will have to keep up with for some time. Do your research online first.

 Adult bed bugs are about 3/16” long and reddish-brown, with oval-shaped, flattened bodies. They are sometimes mistaken for ticks, cockroaches, carpet beetles or other household insects. The immature bed bugs (nymphs) resemble the adults, but are smaller and lighter in color. Bed bugs do not fly, and they don’t jump like fleas do ― but they can crawl rapidly over floors, walls, ceilings and other surfaces. Adult females lay their eggs in secluded places, depositing 1, 2 or more eggs per day, potentially hundreds during their lifetime. The eggs are tiny (about the size of a dust spec), whitish and hard to see without magnification, especially on light-colored surfaces. When first laid, the eggs are sticky, causing them to adhere to surfaces. At room temperatures, bed bug eggs hatch in about a week. Newly emerged nymphs are straw-colored and no bigger than a pinhead.

While cleaning up infested areas will be helpful in controlling bedbugs, getting rid of them usually requires chemical treatments. Because treating your bed and bedroom with insecticides can be harmful, it is important to use products that can be used safely in bedrooms. Do not treat mattresses and bedding unless the label specifically says you can use them on bedding.
