Article by Dana Richardson, Back to Eden Film producer & gardener.
Hello gardeners worldwide! Today we will answer some of the myths and facts about mulch and termite problems. Our goal is toteach you how to avoid termites in mulch. Let me start this article by saying that Paul Gautschi has never had an issue with termites nor have we heard testimonies of any gardeners having termite problems due to wood chip mulch. Nevertheless, one of the common concerns we receive from gardeners is, "does wood chip mulch attract termite infestations?"
What is the best mulch to use to avoid termites?
Did you know that some types of wood chips deter termites and are even toxic to termites!? Cedar, cypress heartwood, melaleuca, southern tidewater red cypress and California redwood are not edible to termites and decrease a termites chance of survival. Research has proven thatCypress heartwood extracts actually are one of the most effective natural repellents of termites. If you are concerned about termites or already have a termite infestation, ask for one of these types of trees mulch when you sign up for a wood chip delivery. The Chip Drop Appis free to sign up for and allows you to make special requests such as this.

Does mulch attract termites?
Although termites like feeding high cellulose organic matter, wood-based mulches aren't going to provide termites with a source for heavy feeding.
Drywood termites are the most common termites to infest your home. This is because drywood termitesfeed on dry wood, obviously! They will usually feed on your home's framing, structural timbers, hardwood floors and furniture. However, drywood do not make contact with the soil. They are able to survive with the little bit of water they find in the dry wood they inhabit. Because drywood termites don’t make contact with the soil, putting mulch in your garden shouldn’t affect their population or provide an attractive food source for them. Furthermore since their colonies infrastructuresare made up of long tunnels that enable them to work together their ability build this infrastructurein wood chips is not possible. The second most common termites species are dampwood termites like the Subterranean Termite.
Dampwood termites do like moist wood and often can be found eating dead or decaying tree stumps and logs. Again, they work in colonies so wood chips don't provide an ideal structure to build tunnels in like they can in a decaying log for example. Although dampwood would find a layer of mulch an attractive habitat to nest underneath, they rarely are less likely to infest buildings do to their affinityto feeding on wet organic matter, not dry structures. In the case they do try to infest a building they would enter at ground level or have to build mud tunnels to enter through an existing opening into in a house. This enables them to travel without contacting sunlight since sunlight kills termites. Bottom line, although an existing dampwood termite colony may enjoy a moist garden mulch habitat they are not likely to infest your home unless your home has an already existingrotting wood problem. Keep mulch away from your foundation to prevent problems.
Will Wood Chip Piles Have Termites In Them?
A termite would not normally live through the chipping process that is used to create wood chipmulch. Even if a few termites were to survive the wood chipper, they wouldn’t survive long after being separated from their colony.Additionally, termites that feed on mulch have a lower rate of survival when compared to a termite that feeds on solid wood.In conclusion, chances of having an infestation of termites brought to your home from a wood chip load is very slim and unlikely. Furthermore have you seen the heat that comes off a turned wood chip pile?! This is a naturally purifying factor in the composting process of wood chip piles that makes them an unlikely habitat for most bug infestations.
How to Avoid Termites in Your Home
Even though wood chips are not an attractive food source for termites, they do like moist soil. So, if you already have a termite infestation in your soil the moisture from the mulch could be an attractive area for them continue to survive. To avoid problems, reduce excess moisture around the siding of your home. If your wood chip mulch is laid down right up to the side of your home, rake it back 12-24 inches to give some space where the dirt lays bare. This will prevent excess moisture around your home that will prevent not only termites but also rotting. Also, make sure your sprinklers aren’t spraying the side of your house to avoid too much moisture at your foundation.
Natural Remedies for Termites
Remember, termites are a natural part of the ecosystem. They are actually one of many insects that help break down wood into compost. So once you've removed the threat from them damaging your home you need not attack them for harmlessly doing their job outdoors. When the termites population has not gotten out of control it is probably due to another disruption in the local ecosystem, solve that first. Are you watering too much near your foundation? Is mulch too close to your home causing overly wet soil? Are decaying logs or dead plants touching your house? If so, fix this and the nature will rebalance on its own.
IF you have wood chips in your garden or in a pile that DO have termites in them do NOT spray it with insecticide! Not only will you create a toxic growing material you will also kill all of the beneficial organismsthat are vital to process of decomposition of wood chips into compost.Even using organic sprays is against the principles of growing with sustainable permaculture methods since it can kill beneficialorganisms.

Although they are non-toxic I'm not sure how your vegetables or beneficial organisms will respond to large amounts of them.If you have a termite problem inside your home, don’t panic and grab toxic pesticides either!
