IPE wood is resistant to termite infestations. These tiny insects eat through wood to live on the nutrients it provides. On the other hand, since IPE wood is so dense, termites have a difficult time eating through the material. A study from the US Naval laboratory showed that IPE wood resisted termite infestations for 15 years in ground. Other types of wood have not been able to withstand termite infestations in that number of years in-ground, but IPE can. Termites prefer wood that’s easier to eat through such as dry or damp wood. That’s why it’s important to select the proper wood products for your deck, such as Brazilian walnut, to prevent structural damage from termites.
