A study performed in Ontario, Canada by Timothy G.
Pine bark mulch allowed the termites to survive between 10 and 14 weeks before dying off completely, though they were only considered healthy up to 10 or 11 weeks. The pine bark mulch ranked sixth. May 04, In the field, termites were detected with equal frequency beneath mulches of eucalyptus, hardwood, pine bark and pea gravel and bare, uncovered soil.
Sustained activity over time was significantly higher beneath gravel mulch. The hospitable conditions beneath mulch likely accounted for the termite foraging activity. Pine straw mulch is resistant to termites insofar as the pine needles won’t give termites the nutrition they need to grow.
That said, they will attract termites to the deep soil beneath the mulch. Take precautionary measures when gardening. Nov 15, Studies show that while termites may feed on wood mulch it is not an adequate source of nutrition. Therefore, it is unlikely that termites would seek it out as a food source.
Cedar mulch lasts for years.
However, subterranean termites favor the cool, moist soil conditions created by mulches, especially inorganic ones such as gravel, which retains more stumpclear.barted Reading Time: 1 min. Termites do avoid pine straw mulch. But pine straw mulch traps the moisture in the soil making the soil more moist. And what does a moist soil do? A damp soil, with pine straw mulch covering it, is a perfect place for the termites to establish their colonies.
It causes the termites to take shelter underneath the mulch’s layer.
