Hard shell Pests represent an interesting issue related to pesticide and the proper selection of a long lasting residual is required. Hard shell Pests tend to harbor outside the home and can be found easily under patio stones, around fire pits, the foundation of your home and in trees. Both predatory and prey these pests have a formidable defence mechanism in a solid exoskeleton that protects their nerve endings from pesticide applications. Applications should be completed on the exterior using a product with a 6-8 week residual to ensure plenty of contact and cleaning. Applications should be focused on the cracks and crevice areas around foundation areas, doors, windows, lights, signage and ventilation. Treating the sunny side of the house with a heavier application will have very effective results.
Roof Rats are less common and typically like to remain in an exterior environment. Roof Rats are slender, agile, quick and just as clever as the Norway rat. Harborage points on exterior can usually be found in trees, or close to an entry point along the exterior of homes and business. Much like the Norway rat these intruders tend to leave similar evidence making improper identification common. Roof Rats prefer to make their harborage outside. However, rafters in warehouse facilities, attics, large vaulted ceilings and troughs where access can be gained by a nearby tree also provide potential harborage points. Control measures are similar for the Roof Rat,. However, taking into account the difference in behaviours placement of traps and monitoring techniques should be tweaked to ensure no improper control measures.
