Buying Guide
Type of Treatment
Start by deciding whether you need a spray, foam, granules, stakes, or a concentrate. Each format serves a different purpose, and the best choice depends on whether you’re treating a spot, a perimeter, or looking for detection.
Indoor vs. Outdoor Use
Some termite products are made for indoor use, while others are specifically for outdoor barriers or perimeter treatment. Always match the product type to the area you want to treat.
Coverage Area
If you’re protecting a large space, look closely at coverage claims. Products that cover more linear feet or square footage may be more efficient for perimeter control.
Application Style
Ready-to-use sprays are convenient, while concentrates may offer more flexibility but require mixing. Foams can be especially useful for targeted areas, and stakes offer a monitoring-based approach.
Prevention vs. Active Control
Some products focus on immediate control, while others are better for ongoing prevention or detection. Knowing your goal will help you narrow down the best termite killer for your situation.
