Signs of termites that homeowners should look out for include mud tubes on walls or foundation, hollow-sounding wood, discarded wings near windows or doors, and the presence of sawdust-like droppings called frass.
It isn't likely that termites are the cause of the sawdust. It would be more likely that it is some sort of ant or beetle. If you continue to see evidence that something is going on, consult with a professional.
Termites!!! Call the exterminator - now!
Carpenter ants dig through wood leaving a sawdust residue. Wood bees or carpenter bees also leave a sawdust residue as they dig into wood to make a nest. Termites actually eat the wood so they would not leave a sawdust residue
Signs of woodworm infestation that homeowners should look out for include small round holes in wood surfaces, powdery sawdust around furniture or wooden structures, weakened or damaged wood, and the presence of adult beetles or larvae emerging from the wood. It is important to address woodworm infestations promptly to prevent further damage to the wood.
Sawdust has many uses, including as a fuel source, animal bedding, compost material, and in manufacturing products like particleboard and paper.
Sawdust is made from wood which contains cellulose- cellulose is not digestible by the human body (unless we had special microbes in our gut like termites) So I can't imagine doing this for flavor but perhaps it may have been useful for preservation of the fish?
One is able to buy bags of sawdust at several different online and retail locations including the following stores: Amazon, Alibaba, and at Butcher and Packer Company.
Sawdust has many uses, including as a fuel source, animal bedding, compost material, and in crafting projects like making wood filler or pressed wood products.
sawdust
Place the sawdust and gravel mixture in water and stir. Let it sit for a time - the gravel will fall to the bottom and the sawdust will float on the top. Density of gravel is greater than water and density of sawdust (wood) is less than water. The layer of sawdust can be carefully removed by skimming it off water's surface or by pouring gravel and sawdust through a series of mesh screens of varying size (the screens can be used with dry or wet mixture)I would use the difference in density of the two materials. A simple method would be to have a stream of the mixed materials poured from a higher elevation to a lower, with a stream of air blowing across the stream. Being less dense, the sawdust will be blown to one side, the gravel will drop straight down. Of course, you COULD just drop the mixed materials into water- sawdust floats, gravel does not. Sawdust will also burn, where gravel will not. Roasting the gravel at a heat above the combustion point of sawdust will cause it to ignite, burning the sawdust away, leaving gravel. Of course, if you have plenty of time, just turn a few termites loose on the mix- they will eat wood- but not gravel!
Yes you can use sawdust provided it is made of pure pine sawdust. It should be noted that as it says in it's name sawdust is dusty and can cause respiratory problems in horses.
Sawdust will not float in water. If you have some sawdust to dispose of, you should always place it in the proper waste containers.
