The importance of clean and hygienic surroundings we live in is of prime importance to stay healthy. The presence of flies, roaches, bugs, ants, insects, and mice can pose a great threat to our health. They multiply rapidly, causing infections and diseases. We just cannot ignore the nuisance these pests can cause to our overall well-being and livelihood. It is why Pest Inspection and management are seeking to either eliminate or regulate the control of pests that are harmful not only to humans but also to the animals and the environment.
Similarly, farmers who grow grains and store them need to ensure that their grain stored on the farm after the harvest is properly fumigated to protect it from insects and pests. It is critically important that growers implement grain fumigation techniques when storing their grains.
There is another terminology that is used to address the issue of harmful insects and pests destroying the stored grains by growers - silo fumigation. Silo Fumigation is a technique that is used to treat a large quantity of grain produced in a storage place or area (also called a silo).
This type of pest control company is usually done to save money and time. All this is because such a treatment process is being able to be carried out in a large area with huge quantities of products in a specific season. It makes the overall cost of treating grains very nominal. Also, such a fumigation process must be carried out after meeting strict protocols laid down for a specific product.
A Complete Guide to Grain Fumigation
To destroy grain pests like the rust-red flour beetle and the lesser grain borer at all their stages (egg, then larva, the pupa, and an adult) phosphine –gas is required to reach and be maintained and that too is only possible in gas-tight storage space.
As mentioned earlier, sealed silos (storage place or storage area), also known as gas-tight silos are always preferred for the storage of grains in the long term. These sealed silos maintain a controlled atmosphere, which also acts as a fumigation chamber for the effective management of pests at all their life stages.
While the process of fumigation of grains is carried out, there are certain key considerations and practices that need to be followed, such as:
For effective grain fumigation to be carried out, a minimum of 10 to 17 days are required.
For affluent results, it is necessary to treat the entire silo, and the amount of phosphine depends upon the size and volume. It is irrespective of how much grain is stored inside – whether full or half.
The phosphine tablets best work when they are placed on surface areas exposed to air. This aids the gas to evenly and thoroughly in the grain stack. In a gas-tight and sealed silo, the tablets are evenly placed in trays before hanging in the headspace.
Either bag chains are hung in the headspace or are rolled flat on top of the grains so that as the gas dissipates from the tablets, it evenly passes around the grains.
At the bottom facilities for passive or active air circulation are provided, so that the gas evenly spreads to even the confined areas in the storage chamber. Improper or no air circulation can lead to phosphine reaching explosive levels.
The concentration of the phosphine gas needs to be at 300 parts per million for the first seven days or 200 ppm for a continuous ten days to control pests and overcome resistance. Affordable Pest Control companies provide best methods of pest control.
On completion of the fumigation process, the silo needs to be opened and ventilated for at least a day. After the ventilation period is over, the withholding period for another two days, thereby, making the entire process to be complete in a total of ten days.
Phosphine is highly toxic and special and careful application is always advised for handling it, or else it could prove fatal. It is why the fumigation should always be handled by expert and trained professionals in the service like Adelaide (A Division of NBHC).
The precinct is known for its use of leading age technology in pest management for all its customers. It is also the first Pest Control Perth to bring in use a web-based technology for affluent and sure shot pest control and management.
Termatrac (unique sensory handheld equipment that helps its operator to locate, ensure and track the presence of termite and activities of any other pest by using sensory radars, thermal imaging, and moisture), PestWatcher (another new age technology software that helps in the monitoring and control of pests) and Glue Board Scanner (a mobile-based application that helps in counting the number of flying insects on a glue board).
Pest Control today has been serving clients in various segments – healthcare, food facilities, the storage industry, and all types of institutions. Their leading age technology implications in the sector of Pest Control Services in Perth have made them an effective solution provider for all kinds of pests and pest-related issues.
