There are several measures that you can take to help prevent termites from accessing and infesting your home. For example, you should correct moisture problems around your house and reduce wood-to-ground contact. By sealing gaps around water pipes and maintaining the integrity of exterior wood, you can help further reduce termite entry points.
There are a few chemical-free termite treatment products available but the effectiveness of these products is limited and often more appropriate to control (not prevent) infestations.
Termite Treatment Without Chemicals
If a termite inspector has identified a termite infestation in your home, there are non-chemical treatment options that may work, especially with drywood termites. These methods include heat, extreme cold and electronic methods. These methods will not work in every situation. Your termite inspector can advise which options will be effective in your home.
Unfortunately, subterranean termite infestations must be directly treated with materials. Modern termiticides are applied in targeted amounts to reduce the amount of materials necessary for control. Bait systems have a small amount of active ingredients to target and control colonies.
Non-chemical alternatives, such as introducing nematodes or ants, can be considered. However, introducing more pests is not a fast-acting or attractive control option for most homeowners. It also can be difficult to measure the success of these solutions.
Is Termite Control Without Chemicals Effective?
There are a few effective non-chemical control methods that target drywood termites. However, these methods will not work with the construction of every house, and they may not work based on the location of the termite infestation. For example, electronic methods and extreme cold only work on localized infestations where the termite control specialist can access the entire termite nest.
Effective treatment for a subterranean termite infestation likely will require some type of chemical application, albeit in limited, targeted amounts. Your pest control expert can explain the materials and methods that use the least amount of termiticide necessary to ensure control.
