If you have crawl spaces or basements where nesting is thought to be happening, apply the Niban there as well. This can be done by simply sprinking the product from the container. This hand powered device will propel the Niban up to 30 feet and will let you treat hard to access crawl spaces that are either too small to enter or simply too dirty to crawl through. Treatments will last 1-3 months depending on the level of infestation. Severe populations will require more frequent treatments until the insects have subsided.
Finished basements are harder to treat, but can be tackled with bait as well.
Use the crusader to apply the Niban behind wall voids, inside electric outlets and into drop ceilings. These are classic problem areas. By direct baiting, you will be getting to where the crickets are living and reproducing. Try to get some treatment behind walls as well. Your efforts will pay off by allowing the bait to affect more crickets quicker.
