Thanks for the invitation to bring my family to your place for Independence Day weekend. It's not every brother-in-law who is so generous to his extended family, and I would like to offer some small token of my gratitude.
It is a modest gift of something I think your otherwise lovely home is in sore need of. I've observed that because of its proximity to the water your property tends to be infested by hordes of insects during this time of year. I've discovered a product that can remedy this. It comes in cylinders of leaves rolled around each other. It comes in various lengths and widths, according to your needs. Don't worry, the composition is purely organic. I'm told the product is made from specially raised tobacco leaves that have been carefully aged and cured. When slowly burned they create an exhaust that repels insects quite effectively.
Some user-participation is required, however, as the product tends to burn out when left alone. Happily, this problem can be easily avoided by occasionally drawing air through the unit's unlit end to keep it smoking. I suppose that you could use some kind of bellows contraption for this purpose, but I find it easiest to resuscitate the unit orally.
From my own observations with this outstanding product, I can conclude that if we were to dutifully keep two of them operating on your outdoor deck from sundown into the evening we would be able to lay down a smoke screen that would effectively protect your house and its inhabitants from harassment by insects.
The repellent works best when used in conjunction with a dedicated glass vessel that is held in the unused hand and filled with alcohol (and ice if the weather suggests). The liquid I use has been carefully treated through years of containment in wood casks. As fumes are released from the wide mouth of the vessel, they combine with the smoke and, for reasons that science does not yet fully understand, further ameliorate the repellent function of the first devise.
The cylindrical repellents I am bringing were manufactured in Nicaragua. Would you prefer the liquid component come from Scotland or Kentucky?
