Beneficial Flea Exterminator nematodes, a type of microscopic worm, can be used in your lawn and other grassy areas to prevent fleas. They can also be used when there is evidence of pests or plant damage; also they can be used as a preventative to help control damaging pests in organic gardens, on your lawn, or in your home. Use beneficial nematodes anywhere you want to limit the exposure of people, pets, or edible plants to potentially harmful chemicals in conventional pesticides. Beneficial nematodes can be applied anytime the soil is not frozen, and is compatible with all other organic products. Once applied, the beneficial nematodes will begin hunting down the pests in your soil, at soil temperatures at or above 55°F. Larval and adult insects are most susceptible to beneficial nematodes. Beneficial nematodes hunt down insects like no chemical can!
• Our Flea Exterminator nematodes search, find, and kill flea larva
• Apply most heavily in the shady areas of our yard, this is where the highest concentration of fleas live and reproduce
• Easy to use: mix contents with water and spray
• Eliminating outdoor fleas is critical to your success in keeping your pets flea free
Flea Exterminator nematodes Do Not harm other beneficial insects; such as ladybugs, honey bees, praying mantis, and earthworms.
For best results apply full recommended dose once per year. One full dose application will help protect your pets, homes and kids better than multiple smaller doses.
All beneficial insects are shipped on Mondays, Tuesdays, and Wednesdays each week (unless it is a UPS shipping holiday delay).
