The answer to 'fumigation bites' is that they are typically caused by exposure to the chemicals used during the fumigation process. Symptoms can include itchy, red, or swollen skin, and in some cases, blisters or rashes. The best solution is to avoid direct contact with the fumigated area until it has been properly ventilated and deemed safe by a professional pest control technician.
If you suspect you've been exposed to fumigation chemicals and are experiencing any symptoms, it's important to seek medical attention right away. While some mild reactions can be treated with over-the-counter medications, more severe cases may require prescription treatments or even hospitalization. It's always better to err on the side of caution when it comes to chemical exposures.
