Termites In Sheds, Fences And Decks

Termites in a shed can reach a home when the shed sits close to the house, when a fence or deck connects the two, or when the same soil colony feeds on both structures. Distance helps, but it does not guarantee separation, because subterranean colonies forage through soil over a wide area. A pro checks the home as well as the shed whenever an outbuilding colony is found, rather than treating the shed alone.

A termite-damaged fence post should be assessed before replacement, because the colony behind the damage needs treatment first, or new timber will be fed on in turn. Once a pro confirms activity has ended, a contractor or homeowner can replace the post, ideally with treated timber set clear of soil build-up. Replacing a post while a colony is active only gives the colony fresh wood.

Decks need termite inspection like homes, especially low decks, decks with timber near soil, and decks attached to a house. Deck timber is exposed to weather, soil, and debris, and damage can hide under boards and in joists. Include decks in each termite inspection, clear debris from beneath them, and report mud tubes, frass, or hollow boards promptly, rather than waiting for the deck to sag.

Mulch around a shed can raise termite risk when it is piled against shed walls or posts, holding moisture and hiding mud tubes, just as it does against a home. Keep mulch clear of shed walls, keep soil levels below timber, and check the shed base during inspection. Mulch is useful in gardens, but against timber structures it creates the damp, hidden conditions termites favour.

Metal or composite decking resists termite feeding better than timber, but a deck is not termite-proof when its supports, joists, or ledger board are timber, or when it connects to a timber-framed home. Termites can feed on the timber parts and use the deck as a bridge to the house. Inspect the timber elements of any deck, whatever the decking surface, and keep supports clear of soil.

Infested firewood near a shed should be moved away from buildings, kept off the ground, and dealt with as a local pro advises, rather than stacked against a shed or home. Do not bring infested wood indoors, and do not burn it indoors without advice, because handling can scatter insects. Note where the wood came from and what signs you saw, and let the pro check whether a colony reaches nearby structures.

Subterranean termites need soil contact or a moisture source, so a fence colony usually connects to soil through posts or mud tubes, even when damage appears high on a rail. Drywood termites, by contrast, can live in dry fence timber with no soil contact. A pro identifies the species from the signs, because the treatment plan differs: soil routes need colony treatment, while drywood timber needs timber treatment.

Outbuildings should be checked during each termite inspection of the home, and by the homeowner between visits, especially after storms, flooding, or landscaping changes. Sheds, fences, and decks change with weather and soil, and a gap that was clear last year can close with mulch or soil build-up. A quick seasonal check for tubes, frass, and hollow timber catches most problems early.

Whether a termite bond covers sheds and fences depends on the document, which usually names the covered structures. Some bonds cover the main home only, while others list outbuildings for an added fee. Check the named structures before assuming a shed, fence, or deck is covered, and ask what added cover costs if those structures matter to you, so there is no surprise at claim time.
