Frequently Asked Questions
How often should Naperville homes be inspected for termites?
Annually for all homes. More frequently (2-4 times per year) if: you’ve had termites before, neighbors have termite problems, your home has moisture issues, or you have favorable conditions (wood mulch, wood-to-soil contact).
Does homeowners insurance cover termite damage?
Generally no. Termite damage is considered preventable maintenance. A few specialty policies offer termite coverage as an add-on. Prevention and treatment are much less expensive than repairs.
How long does termite treatment last?
Liquid treatments: 5-10 years with annual inspections. Baiting systems: Ongoing protection with regular monitoring. Warranties: Typically 1-5 years with renewal options.
Can I prevent termites myself?
You can reduce risk through moisture control, removing wood-to-soil contact, proper landscaping. However, professional prevention treatment is much more effective and includes warranty protection.
Are termite treatments safe for my family and pets?
Yes. We use EPA-registered products applied by licensed technicians. Products have low toxicity to mammals. Interior access restrictions are minimal (usually 4-6 hours).
What time of year is best for termite treatment in Naperville?
Spring (March-May) is ideal before swarming season, but treatment is effective year-round. Winter can actually be advantageous as termites are more concentrated in colonies.
