No. Each treatment is billed as it is completed. We can leave the invoice at your door, send it by mail or email-your choice.

A good rule of thumb is to wait two hours, no matter the weather. If it’s rainy, the treatment will absorb into the soil. If the weather is clear, the treatment needs time to dry. Exactly how long will depend on how humid and/or windy the conditions. You can check the drying status by wiping a paper towel over the grass. Once the treatment has dried, there is no risk of exposure to people, pets, or wildlife.

Unless your lawn is exceedingly overgrown (over 6”), there’s no need to mow before the treatment. After the treatment, we recommend waiting at least one day to mow. Although if the lawn is mowed before that, there’s no cause for panic. The liquid nature of our bio-fertilizer ensures that the treatment ends up in the root zone, not stuck on the blades of your mower.

Rain is beneficial to fertilizer treatment and rarely interfers with any weed control. Give us a call if the weeds still look healthy after 3-4 weeks.

Tree and shrub pest treatments will tolerate moderate rainfall. Once dried, rainfall and/or irrigation will not wash it away, thanks to a treatment component that adheres the product to the plant.

We, like you, are concerned about accidental exposure issues. Pest control products are occasionally necessary, e.g. to manage weeds and insects, but proper use will not present any unreasonable risk to humans, pets, wildlife or the environment.

Most of the control products we use are in the same class as Lysol Disinfectant Spray- bearing a “caution” label. Just like you do with your household cleaning products and medicines, we have taken steps to minimize exposure to the control products.

Our lawn application equipment is designed to allow spot treatment of weeds and insects while fertilizer is being applied, minimizing the risk of off-target contamination and run-off. We always choose the least toxic control products and never use poisons in any landscape treatment.
