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.
DIY approaches come with risk. It's not uncommon for someone to use a pest-control bomb or fogger that is available over the counter. These don't work well against bed bugs, according to research from Ohio State University. They can also expose people to toxic chemicals. Neither are over-the-counter aerosol insecticides effective against bed bugs. Most of these products have either pyrethrin or a pyrethroid as a main ingredient and those compounds have the same mode of action as DDT, which bed bugs have become resistant to. If you spray the bug directly you might kill it, but that is not going to get rid of the infestation. The problem is finding all the bed bugs. Some just can't be reached with insecticide. It's difficult for nonprofessionals to do anything more than kill what they can see, but that's just the tip of the iceberg in terms of what's there.
If you suspect an infestation, experts recommend finding a professional exterminator who has experience dealing with bedbugs. Sprayed insecticides are commonly used to treat infestations, and exterminators may also use nonchemical methods, such as devices to heat a room above 122 degrees Fahrenheit (50 degrees Celsius), a lethal temperature for bedbugs, according to the Mayo Clinic. Freezing infested items for a few days at temperatures below 0 F (-18 C) may also put bedbugs to permanent rest, according to the University of Minnesota. But you may have to throw out heavily infested mattresses and other items of furniture.
Some preparation is still required (e.g. removal of heat-sensitive items such as aerosol cans, indoor plants and medications), but it is seldom necessary to bag, launder and/or hot dry bedding and clothing since these items will be heated along with other furnishings. Another advantage of heat treatment is that infestations can often be eliminated in one day, rather than over multiple days or weeks. Conversely, heat treatment alone has no lasting (residual) effect should bed bugs be reintroduced into the dwelling. Consequently, some companies recommend concurrently applying residual insecticides. To further minimize reintroduction, occupants are advised to take as few belongings as possible with them while the heat treatment is in progress.
Three days after the initial “feeding” the sores hurt really bad. They itch like no other. By the way, none of my roommates have experienced this. I started panicking and washed all my clothes and sheets. I checked every corner of my room. Nothing. I couldn’t find anything, so them things must be hiding pretty well. Unless it isn’t bedbugs. Today I woke up and realized I had three more bites on my arm just above my elbow in the “breakfast, lunch, and dinner” pattern this site talks about.
Bites on dogs and cats will look much like bites on people, and the pet owner may actually suspect a mosquito or flea bit the pet. As with people, bed bugs do not stay on pets, but return to a protected harborage site after feeding. In addition to bites, the presence of the bug’s feces, cast skins and the animal’s irritation at night are also indicators of bed bugs biting pets. Therefore, one of the best things to do is inspect the pet’s bedding and frequently groom the animal while being vigilant for the telltale signs of bed bug presence.
