This procedure is a general treatment done with an insecticide spray. The purpose behind it is to protect the property from a potential insect infestation. For example, most tenancy agreements often include a clause regarding a mandatory property fumigation. When the time for your house fumigation arrives, a fully equipped technician will visit your address to apply the product and keep the pesky bugs at bay for weeks to come.
For your safety and for optimal results, there are a few checklist boxes that you need to tick on the morning before the specialist arrives, namely Remove any pets from your property, fish included; Hoover all areas that are about to be treated. When the London exterminator begins the fumigation, leave the property for about 2 hours, then air out the treated premises for 5 to 10 minutes. Avoid hoovering the treated areas for at least 4 days.
