Will I get your pre-payment discount if I buy online?

How can I tell the difference between Winter Moth and Gypsy Moth caterpillars?

Though both pests are common in Massachusetts, your trees are more likely to have a larger infestation of Winter Moth caterpillars. Winter Moth caterpillars are smooth and green, where as Gypsy Moth caterpillars are brown with long hairs. Both caterpillars can cause extensive damage to your trees and should be treated immediately. Learn more about our treatment options here.

Are your products certified Organic?

The health of our environment is of our utmost concern, therefor all of our products are OMRI-listed (Organic Materials Research Institute) and NOFA (Northeast Organic Farming Association) allowed. Many of our products are made in-house from organic materials. We take care to spray our products before blooms as to not disturb the bees and other pollinators. None of our products are harmful to humans, pets or wildlife, so you can feel good about protecting your trees without the use of harsh chemicals. 

Does Organic really work?

Yes! We have spent the past 40 years developing sustainable proactive and reactive plant health care solutions that have revolutionized the tree care industry. Boston Tree Preservation’s aggressive approach to tree care and soil health actively encourages their wellbeing with organic programs specifically designed to promote and ensure tree, shrub and lawn good health. Healthy trees and landscape are more likely to resist diseases and insect pests.

As with human health, preventative measures are always better. Using time proven techniques that include expert analysis and the appropriate combination of professional skills, services and environmentally friendly products, the health of your entire landscape can be improved and prolonged.  Protecting your landscape with organic, proactive programs are more cost effective too than 911 reactive services administered after the damage has started. 

An organic, proactive approach benefits you, the trees, and the earth.

I heard Spinosad kills bees, is that true?

It's all about timing. Though Spinosad has zero mammalian toxicity, if it is sprayed while the tree's flowers are in full bloom it can decrease the bee population. This is why we carefully time our applications and spray only while flowers are in their budding stage. This is effective for minimizing the population of unwanted pests before bees start their pollination process.
