As rat biology and behavior are progressively researched, the resultant investigative insights provide pest management professionals with intuitive rat pest solutions. When a PMP is between a rat and a rodent place, knowing the rats’ capabilities results in radical rat reduction as well as robust recurring revenue.
- Extend and reach approximately 13 inches above a flat surface.
- Can jump at least 36 inches above a flat surface.
- Submerge and swim for up to 30 seconds.
- Can swim up to a half-mile.
- Can swim up and through toilets.
- Roof rats can walk horizontal and vertical wires.
- Can crawl along conduits and pipes.
- Can pass through openings > Â½ inch square.
- Can climb the interiors of 1Â½ to 4 inch diameter pipes.
- Can climb the exteriors of 3-inch pipes.
- Can climb conduits and pipes within 3 inches of walls.
- Gnaw wood, glass, synthetic building products, lead pipes, cinder blocks, aluminum, and sheet metal
Possible Number of Rats
- No rats to a few rats present when no physical evidences are found after a sighting. A possible recent invasion of <5 rats.
- A moderate number of rats present if aged evidences of gnaw marks and droppings are found. If no daytime sightings, but >1 sighted at night in an area, possibly >5 rats per sighting area.
- Large numbers of rats present if fresh gnaw marks, droppings, and tracks are found. If three or more rats are seen during the day and at night, possibly >15 rats are in the area.
- For a “ball park” or approximate number of rats for a specific area, use the following math:
- Number of burrow openings counted divided by 3 openings per burrow equals approximate number of burrows.
- Number of burrows times 8 rats per burrow equals approximate number of rats.
- Example: For a specific area you count 60 burrow openings. 60 openings divided by 3 openings per burrow equals 20 burrows. 20 burrows times 8 rats per burrow equals approximately 160 rats.
Radical Rat Reduction
- Bait stations with clear labeling.
- Bait station systems for many environments (disguised as utility boxes, rocks, to go underground, or to work within most interior and exterior structural niches).
- Rodenticide baits with high quality, environmentally friendly, decidedly effective active ingredients of various formulations (liquid, meal, pellets, paste, and block).
- Non-toxic baits for detection of rat activity or census.
- Florescent bait technology assures program efficacy by tracking rat activity through urine and dropping behavior.
- Advanced design mechanical traps for challenging environments or where rodenticides cannot be used.
- High quality food attractants increase mechanical trap placement effectiveness.
- Innovative glue board systems used within sensitive areas.
Know the rats’ capabilities. Know the number of rats. Know radical rat reduction. Then know robust recurring revenue!
