Outdoors, it can be applied around foundations, patios, decks, and garages to deter recurring pest activity. This versatility makes it a practical choice for establishing both interior and exterior defenses against pests.
Ortho Home Defense Max Indoor Insect Barrier

Ortho Home Defense Max Indoor Insect Barrier is designed to kill ants, roaches, spiders, fleas and ticks while offering a full year of continued protection on nonporous interior surfaces. It is well-suited for use in kitchens, bathrooms, basements, and around doors and windows. The product also provides outdoor perimeters to create a continuous barrier around the foundation, helping reduce pest ingress. Its extended-reach wand broadens spraying options for convenient application.
Ortho Home Defense Insect Killer Refill2

This refill option continues Ortho’s indoor perimeter protection, delivering a long-lasting barrier against ants, roaches, spiders, fleas, and more for up to 12 months on non-porous surfaces. It mirrors the core benefits of the original formula, making it a convenient option for households already using Ortho products. It is ideal for recharging existing application systems when you want consistent, recurring pest control around the home.
Upgraded Ultrasonic Pest Control Repeller

The ultrasonic repeller uses multiple sound frequencies to deter fleas, roaches, rodents, ants, mosquitoes, and other pests without chemicals. It is designed for whole-house coverage and features low power consumption. This option appeals to households seeking a non-toxic, maintenance-free approach, especially where chemical presence is a concern for children and pets.

Buying Guide
When selecting a spray for pest control, consider the following factors to align with your home’s needs:
- Scope of coverage: Indoor-only, perimeter-only, or combined indoor and outdoor use. Decide based on where pests are most active.
- Duration of protection: Some formulas offer up to 12 months of surface protection on non-porous materials; others emphasize continuous barriers. Verify applicable surfaces.
- Target pests: Different products target specific pests (ants, roaches, spiders, fleas, ticks, rodents). Choose according to the most prevalent invaders in your area.
- Application approach: Sprays with long-reach wands are helpful for hard-to-reach spots; pump sprayers provide versatile usage for plants and outdoor areas.
- Safety and usage: Indoor products may require ventilation and surface compatibility checks. Ultrasonic repellents provide chemical-free options but may vary in effectiveness for larger spaces.
- Environmental considerations: For households with kids or pets, weigh chemical-based products against non-chemical methods like repellents and barrier formulations.
- Maintenance and refills: Some systems require periodic refills or recharging; plan for ongoing pest management rather than a one-off solution.
Overall, combining an indoor-perimeter spray with a perimeter-focused barrier and a non-chemical option like an ultrasonic repeller can create a layered defense. Consider your home layout, entry points, and the pests most commonly reported in your region to tailor a defense strategy that minimizes repeated infestations over time.
