wasps in wood burning fireplace

0

    I have a house built in 1985 with a wood Burning fireplace. I have not had a fire in it in 20 years. Last summer (2014) I saw many wasps enter through a wide variety of holes. I sprayed about 6 cans of wasp killer spray into the holes where they entered. I then caulked as many of the holes as I could reach. This spring more wasps are around the brick fireplace and entering more holes. I need help because different professionals give different advice – “start a large fire in fireplace”,  “keep spraying”, “get a pro”, etc., etc. What would you recommend?

    Fireplaces are a direct route into any home. And if not in use, they will most certainly become a nest site for a wide range of insect pests. In general, many will nest and never be noticed because they’ll use the spaces for resting and nesting yet still feed outside. But some pests, like wasps, will readily fly around and this flying will many times cause some to end up inside the home.

    Controlling the problem can be accomplished a few ways depending on what you’re comfortable doing, not doing, etc. But two things you don’t want to do is spray wasp freeze and second, use caulking. Wasp freeze has no residual and though it might kill some wasps, you can never kill enough to get rid of them. And since its highly invasive, it actually creates better cracks and crevices for wasps to use for new nest sites.

    As for caulking; there is no way you can seal every entrance into your home. In fact the more areas you seal the more nest sites you create because wasps will learn to get in behind the caulking because it will be forming nice little pockets ideal for this use. And since most siding has these gaps as part of the homes natural design, sealing them up will generally only make matters worse.

    So what can you do? Fortunately there are some options.

    Clearly hiring a service company to thoroughly treat the exterior and inside the flue would be the easy way out. But chances are high they’ll only offer a short term “guarantee” and within a year, their treatments will wear away thus needing to be renewed. That means you will have to keep forking over a service fee if you want to keep living areas wasp free. But no doubt, this is an option. And if they treat right, they will accomplish said goal.

    Another option would be to start burning wood in the stove. Unfortunately a “big” fire alone won’t do it. In fact, it tends to make matters worse because the odor left behind when you cease burning will naturally attract wasps. So unless you want to burn every day for an hour or two, the space will simply get infested within a short time once you stop.

    So if you don’t want to keep burning, consider treating yourself. Using the right products will yield the right results and that’s where we can help.

    The first step in treating the problem yourself would be to thoroughly dust the homes exterior siding with DRIONE DUST. This will stop them from entering and since Drione will last 6-12 months, you only need to treat once a year. Now if  you can’t reach all areas, use a DUSTICK.

    The last bit of “treating” needed will be to set up an AEROSOL MACHINE just above the flues damper. These machines are small and will fit up inside any flue. Fill the machine with a METERED INSECTICIDE  and turn it on. Refills last 30-40 days and they’ll release a small blast of pyrethrin based aerosol every 15 minutes that will kill insect pests as they enter the flue. In fact it will work as a repellent for all pests keeping moths, flies, bees, wasps and more from coming inside. Keep the machine running from spring through fall and combined with the Drione treatments, you’ll be able to keep out any pest including wasps.
