Q&A Home

Thomas from Houston, Tx writes,

How do I use the insecticide ports outside my house?

I just moved to Texas and the house I purchased has several ports around the perimeter that I am told are for insectide to be applied to the house through tubes in the walls. We've just encountered our first roach after having received a clean pest inspection during the purchase. Can I use these ports myself? What kind of product do I apply? What is the method of application?


We only carry one product labeled specifically for use in the wall delivery systems which would be the Optigard Flex. That being said, we have always been told that a homeowner would not have the proper equipment to utilize the in wall system and it requires a specific high pressure applicator for the ports. However, you can do a general spray like most companies would do with a product like Suspend Polyzone which can be mixed with water and sprayed indoors and outdoors for pest control. Suspend works extremely well on roaches as well as a multitude of other pests like ants, spiders, millipedes, mosquitoes, etc. It dries clear, has no odor, doesn't stain, and can be used inside along baseboards and cracks and crevices, and outdoors around the foundation, window and door frames and bushes and shrubs where pests will harbor. Suspend Polyzone will last up to 90 days outdoors and at least 90 indoors as well.
