Soak in saltwater to kill beetles and larvae
Oyster mushrooms are a delicious treat, but they can be subject to insects, organic matter, and other things that you typically won't find on food in the produce aisle of your local grocery store. One way to clean them is by soaking them in saltwater to kill beetles and larvae.
First, trim any obviously bitten or discoloured areas of the mushroom and slice across the base of the stem to check for bug holes. These small, circular holes indicate that larvae have hatched and are crawling inside your mushroom. If you see a large number of holes, trim the stem until you don't see any more.
Next, prepare a saltwater solution by adding a couple of tablespoons of salt to a few cups of water. You don't want the mushrooms to become too salty, so don't add too much salt. Place the mushrooms in the saltwater solution, gill-side up, and soak for no more than 5-10 minutes. Soaking for too long will cause the texture of the mushrooms to degrade.
During the soak, the saltwater will draw out and kill any bugs and larvae inside the mushrooms. It's important to note that this method may not remove every single larvae, but it will remove 99% or more. If you spot some larvae during the cooking process, simply pick them out.
After soaking, remove the mushrooms from the saltwater and gently rinse them with fresh water. Then, place the mushrooms gill-side down on a paper towel or kitchen towel and gently press down to soak up any excess water. Leave them to air dry until they are fairly dry and then proceed to cook them as desired.
While this method is effective for killing beetles and larvae, it is important to note that it may not be suitable for all types of mushrooms. For example, fragile mushrooms such as Shaggy Manes should not be soaked in saltwater. Additionally, some people believe that soaking mushrooms can negatively impact their flavour and texture and change the cooking process. However, if you are concerned about insects and larvae, this method can be a safe and effective way to clean your oyster mushrooms.

Rinse with clean water
Rinsing oyster mushrooms with clean water is an effective way to clean beetles from them. Before rinsing, trim any areas of the mushroom that are obviously bitten or discoloured. Also, slice across the base of the stem to check for bug holes. These small, circular holes indicate the presence of fungus gnat larvae or similar bugs crawling inside the mushroom. Continue trimming up the stem until no more holes are visible.
If no bug holes are found, proceed to lightly rinse the mushroom with clean water. After rinsing, place the mushrooms gill-side down on a paper towel or paper bag. Use another paper towel to gently press down on the mushrooms and soak up excess water. Repeat this process until the mushrooms are fairly dry.
It is worth noting that rinsing with clean water is not the only method to clean beetles from oyster mushrooms. Some people suggest soaking the mushrooms in saltwater for a few minutes before rinsing them with clean water. This method is said to quickly draw out and kill bugs and larvae that may be inside the mushrooms. However, it is important not to soak the mushrooms for too long, as this can affect their texture.
Additionally, when dealing with oyster mushrooms, it is important to be aware that beetles often get deep down into the gills. Therefore, it is recommended to run your finger across the gills during or after rinsing to do a quick check for any remaining beetles or other bugs.

Dry with a paper towel
Oyster mushrooms are commonly home to beetles and other bugs, so they need to be cleaned thoroughly before cooking. Firstly, trim any areas of the mushroom that are discoloured or show signs of bite marks. Slice across the base of the stem to check for bug holes, which indicate the presence of larvae. If you find any bug holes, continue trimming up the stem until they are no longer visible.
After trimming, give the mushrooms a gentle rinse with cold water. Then, place them gill-side down on a paper towel and gently press down to soak up excess water. You can also use a dry towel if you prefer, or if you plan to make a slurry with the mushroom liquid. Repeat this process until the mushrooms are fairly dry.
Alternatively, you can soak the mushrooms in saltwater for a few minutes to kill any bugs or larvae. Use only a couple of tablespoons of salt per few cups of water, and do not soak for more than 5-10 minutes to avoid damaging the texture of the mushrooms. After soaking, rinse the mushrooms with cool water and place them on a paper towel to dry.

Trim discoloured areas and check for bug holes
Oyster mushrooms are often infiltrated with bugs, such as beetles, which can get deep down into the gills. A quick way to check for bugs is to run your finger across the gills. If you see holes in the cap of the mushroom, this is a sign of bug damage. If you see a number of holes running down the stem, it is likely too bug-infested to eat.
To clean oyster mushrooms, trim any discoloured or obviously bitten areas of the mushroom. Slice across the base of the stem to check for bug holes. These small, circular holes indicate the presence of fungus gnat larvae or similar pests crawling inside the mushroom. The eggs are usually laid in the base of the stipe, and the larvae travel upward, so you can keep trimming the stem until you no longer see holes at the bottom. If you don't see any bug holes, give the mushroom a light rinse, then leave it on a towel to dry before using it.
If you want to kill any bugs or larvae inside the mushroom, you can soak it in saltwater for 5-10 minutes. Use only a couple of tablespoons of salt per few cups of water, as the mushrooms may become too salty otherwise. After soaking, leave the mushrooms gill-side down to dry before using or storing them.

Check gills for beetle eggs
Oyster mushrooms are a delicious treat, but they are often infested with beetles. These beetles like to get deep down into the gills of the mushroom, where they lay their eggs. To check for beetle eggs, carefully inspect the gills for tiny 2-3 mm black dots, which could be beetle eggs or larvae. These dots may be difficult to see with the naked eye, so it may be helpful to use a magnifying glass or microscope. Another way to check for beetle eggs is to slice across the base of the stem to look for bug holes. The eggs are often laid in the base of the stem, and the larvae travel upward, so trimming the stem until no more holes are visible can help remove the beetle eggs.
If you plan to consume the oyster mushrooms, it is important to remove any beetle eggs or larvae. While some beetles may not cause visible damage to the mushrooms, others can tunnel into the mushroom flesh and contaminate it. In addition to inspecting the gills, you can also soak the mushrooms in saltwater for a few minutes to draw out or kill any bugs or larvae. However, do not soak the mushrooms for too long, as this can affect their texture. After soaking, place the mushrooms gill-side down on a paper towel or paper bag to dry.
To further prevent beetle infestation, it is important to store oyster mushrooms properly. Make sure to keep them in a cool, dry place and to use them within a few days of harvesting. You can also try to grow oyster mushrooms in a controlled environment, such as an indoor mushroom farm, to reduce the risk of beetle infestation.
Checking the gills of oyster mushrooms for beetle eggs is an important step in ensuring their safety for consumption. By carefully inspecting the gills and removing any visible eggs or larvae, you can reduce the risk of consuming contaminated mushrooms. Proper storage and preparation techniques can also help to reduce the presence of beetles and their eggs in oyster mushrooms.
