According to the U.S. Environmental Protection Agency, pyrethrins and pyrethroids are the most common chemical compounds used to get rid of bed bugs. These chemicals force bed bugs out of their hiding spots and kill them on the spot so they are eliminated for good. Only professional exterminators can apply these treatments, and they are reserved for severe infestations.

You will need to discuss with your pest control expert to know when and what to clean after the treatment. Sometimes, you may have to wait a couple of weeks for deep cleaning to avoid wiping up the treatment they applied.

However, you’ll want to wipe down any surfaces you use for food prep and eating. Before the treatment, you’ll also want to make sure that items such as pet dishes and children's toys won’t be exposed to the chemicals.

No, phorid flies do not bite humans or animals. However, they can still be harmful to humans. Since phorid flies feed on decaying organic matter and are found in unsanitary conditions, they can transmit disease organisms onto foods and food preparation surfaces. If you suspect that your home has a phorid fly infestation, protect your health by taking immediate action to eliminate it.

Some animals, such as bats or birds, will be able to get out of chimneys on their own since they can fly. Other animals, however, may have a harder time and will require the help of a professional to escape. Squirrels and raccoons in particular may become stuck inside a chimney, especially if you have a buildup of soot or creosote inside. This can prevent them from being able to climb out, in which case you’ll need to call an animal control expert to help remove them.
