What it is
What is the 4D Barrier Pest Defense System?
The 4D Barrier system creates four treated barriers between the desert and your living space — the fence line, the yard, the home perimeter, and the interior. Our specially trained technicians use the latest IPM devices, products and techniques to establish protective barriers that exterminate and repel pests before they reach your home.
The 4D Barrier Pest Defense System is safe and effective, and specially designed to help you and your family feel secure and comfortable in your home again as soon as possible.
Most pest control treats the house. This treats everything between the pest and the house — which is why the interior needs treating only semi-annually or annually after the initial visit.
How it works
Four barriers, worked from the outside in
- 1
The Fence Line
The first barrier against unwanted pests is the fence line. We spray the wall and landscape along the fence line, and dust inside the wall voids of the fence to get the bugs where they live. As new pests cross over this barrier coming from your neighbour’s yard, they are repelled by it, or cross over and come into contact with the pesticide and begin to die.
- 2
The Yard
The second barrier is the entire area between the fence line and the home perimeter. We apply time-release granules to the lawn and/or landscape rock, and bait around shrubs and tree beds. We also spray curbing, rock rivers and rock borders that insects use as natural foraging trails, and dust valve boxes and other common moist harbourage areas.
- 3
The Home Perimeter
Third is the actual home perimeter, where we spray the entire perimeter including the stem wall and landscape. We also spray and dust at all doors into the home including garage doors. When possible we spray around windows, vent frames, lower eaves, and any other access point that pests might use.
- 4
The Home Interior
The home interior is the last line of defence and, after our initial treatment, needs only be treated semi-annually or annually. When we treat your home interior we spray all entry points and nearly all of the interior perimeter, and we spray and dust the garage. Sticky monitors and traps are also used as needed to stop any stray pests from getting into your home.
