Japanese beetle & Bagworm prevention in Omaha

Japanese Beetles can fly up to 5 miles per day. Even if grub control prevents beetles from emerging from YOUR lawn, beetles are still flying in from:

Neighboring properties without grub control

Ditches, parks, and farm fields

Golf courses and other unmaintained grassy areas

Grub control protects your lawn from grub damage but cannot prevent adult beetles from flying onto your property. That's why foliar (tree) spray is necessary—you must kill the beetles ON your trees to prevent damage.

Yes, it is almost certain. If you have them attacking your landscape one year, they will return every year. However, the severity varies year to year based primarily on weather conditions:

Wet spring: More grubs survive = more adult beetles emerge

Dry spring: Some grubs die from drought = fewer beetles

Temperature: Warm early summer accelerates emergence; cool weather delays it

The beetles will keep coming back because they're constantly being produced in untreated areas within flying distance. Annual preventative treatment is the only way to protect vulnerable trees.

We take precautions to minimize impact on beneficial insects:

Targeted application:  We spray only affected trees, not entire landscapes

Timing:  Applications during June-July target specific pests during their vulnerable stages

Quick dry time: Once dry (1-2 hours), residual impact on pollinators is minimal

Best practice:  we will not spray flowering trees or shrubs.  Pollinators are affected by pest control products that live in the vascular system of trees and plants that they come into contact with while pollinating the flowers.

June and July are the ONLY effective treatment window. Here's why:

Japanese Beetles: Adults emerge in June and feed through August. Treatment must occur while they're actively feeding.

Bagworms: Eggs hatch in late May/early June. Young caterpillars are vulnerable June-July. By August, they're too large and protected by their bags.

Too early (May): Pests haven't emerged yet; insecticide will be gone before they arrive

Too late (August+): Japanese Beetles are finishing their cycle; Bagworms are too mature to kill effectively

Our 2-application program (one in June, one in July) provides optimal protection during the vulnerable window.

Results depend on the pest and infestation level:

Japanese Beetles: Existing beetles on treated foliage die within 24-48 hours. However, new beetles may fly in daily, so some beetles may still be visible (but damage is greatly reduced).

Bagworms: Young bagworms die within 24-72 hours of contact/ingestion. Older bagworms (late July+) may take longer or require multiple treatments.

Damage prevention: New leaf/needle damage should stop or dramatically decrease within 3-5 days after treatment

Hand-picking is an option for VERY small infestations (5-10 bags on accessible branches). However:

Labor-intensive: Must find and remove every single bag

Miss one = hundreds more: Each bag contains 500-1,000 eggs. Miss one bag, and next year's infestation will be worse

Accessibility: Many bags are 20-60 feet up in tree canopy—impossible to reach

Timing-critical: Must remove bags before August when eggs are laid

Not preventative: Only removes visible bags; doesn't protect against new arrivals

For any significant infestation or trees over 15 feet tall, professional spray treatment is the only practical solution.

Absolutely! Many customers choose selective treatment based on:

Tree value: Treat expensive specimen trees or those with sentimental value

Visibility: Treat highly visible trees (front yard, near patio) but not hidden ones

Past damage: Treat trees that showed damage in previous years

Species vulnerability: Prioritize Lindens (Japanese Beetle favorites) spruce, and Junipers (Bagworm favorites)

During the on-site estimate, we'll help you identify which trees are most vulnerable and prioritize treatment based on your budget and concerns.
