Honestly — not reliably. For an active termite infestation, DIY products usually make things worse. Sprays and foams kill only the termites you can see and cause the rest of the colony to relocate elsewhere in your home, while the nest survives. Eliminating a subterranean colony needs professional treatment.
Surface insecticides are contact killers. You kill the foragers you can see, the colony senses the disturbance and reroutes, you lose track of where it's gone, and the feeding continues out of sight. People often believe they've solved it — then discover far worse damage months later.
The useful DIY is reducing the conditions termites love: fix leaks and drainage, keep firewood, timber and mulch away from the house, improve subfloor ventilation, clear garden beds piled against brickwork, and don't store cardboard or timber against walls. This lowers your risk — but it won't clear a colony that's already established.
Any sign of active termites — mud tubes, hollow timber, or swarming winged termites — means it's time for a professional. A technician finds the colony and treats it at the source with a barrier or baiting system, then monitors to make sure it's gone.
An inspection costs a few hundred dollars. Undetected termite damage runs into the thousands or tens of thousands. Getting it checked early is the cheap option, even when nothing turns out to be wrong.
They kill the termites they touch but don't eliminate the colony, and they often drive it to relocate within your home. They aren't a reliable fix for an active infestation.
No. The visible termites are a small fraction of the colony, which usually nests elsewhere — often underground. Spot-treating misses the nest entirely.
Yes — prevention. Controlling moisture and keeping timber and mulch away from the house genuinely lowers your risk. Actual colony treatment is a job for a professional.
