## Description

desertcart.com : BioLogic's Scanmask Beneficial Nematodes, Steinernema feltiae Sf Nematodes for Natural Insect Pest Control (50 Million) : Patio, Lawn & Garden

Review: Ver Effective for fleas & beetles when applied properly - Been using this for a few years now for backyard fleas; very effective- and it’s annihilated the Japanese beetles too. IMPORTANT- I found I must make sure to order it in the spring when temperatures are under 80 F, and apply immediately to soil that’s already a little wet.
Review: A Great Product for Organic Gardeners - I have had very good results using this product to control rootworms in my organic garden. BioLogic does a great job of packaging the product carefully with long-lasting cold packs and insulation to keep the nematodes viable. The instructions for use are important, but no more difficult than for chemical treatments, and this product has the great advantage of being non-toxic to humans and pets. Take care that the product is used in a way that keeps the nematodes alive - keep them refrigerated prior to application, apply in the evening or on a cloudy day, and water the soil before and after applying. It is certainly not difficult, and well worth taking the time to do correctly. I have had far fewer problems with rootworms in years when I've used this product. And when I've had questions, I have received quick and knowledgeable responses from the folks at BioLogic. Highly recommended.

## Questions & Answers

**Q: Does this kill deer ticks?**
A: Unfortunately, there are no nematodes that effectively kill ticks in field conditions.  They have been shown to kill them in the laboratory, but never a successful field trial.

**Q: Looking to kill fleas. we live on the gulf coast of fl - can we apply these to our yard during mid-summer, when it's hot, muggy and rainy?**
A: You can apply when hot.  But you need to water down good.  We use the ones on a sponge

**Q: Is it safe for indoor potted plants in order to kill gnats, and is it safe for any plants (I'm concerned nematodes might hurt the roots)?**
A: Yes totally safe.  The nematodes that harm roots are a different species.

**Q: Will this brand of nematodes hurt bees?**
A: Nematodes live in the soil, they are microscopic worms that eat the larvae of insects. To my knowledge Bees do not live or bread in the soil

I used this product due to the problem we have with the pine beetles in Colorado. I think it has really helped. I will try this process again this coming summer just to make sure.
