Why you need to control rats and mice
The commensal rodents, those usually found associated with people, are the brown rat (Rattus norvegicus), the black rat (Rattus rattus) and the house mouse (Mus musculus musculus and Mus musculus domesticus). (It should be noted, however, that the black rat is no longer a significant pest in the UK, being confined to probably one dockside area only). Commensal rodents have been pests since time immemorial and have resisted all attempts to eradicate them. This is hardly surprising, given that they are highly adaptable, omnivorous creatures with tremendous reproductive potential, acute senses and a high degree of athleticism. Moreover, as recent studies such as the National Rodent Survey in the UK demonstrate, their numbers are not diminishing. The costs attributable to rodents in both financial terms and in human suffering are enormous and commensal rodent control is rightly given a high priority by local authorities, businesses and householders.
Rats and mice are found wherever there is food and shelter. The availability of such resources dictates population density. In ideal conditions, a pair of mice can produce more than 2000 offspring per year and a pair of rats 200 per year. Their gestation period is only 21 days and therefore population explosions can occur when effective control is not implemented.
INTEGRATED PEST MANAGEMENT - Effective rodent control requires a combination of measures including surveys, proofing, habitat manipulation, sanitation and control techniques. Proofing, habitat manipulation and sanitation should all be carried out after control techniques in order to avoid creating neophobic conditions, delaying bait takes.
A survey is necessary to identify the type and extent of the infestation in order to allow informed decisions to be made with regard to the proofing and hygiene measures required and the type of control techniques to be employed. Visible signs include droppings, smear marks, tracks and urine pillars.
Eliminating rodents from the inside of a building will only be a short-term solution if there are others outside that can then get in. Black rats and brown rats can climb drainpipes or trees and enter through high apertures. Brown rats can burrow in or enter via drains and sewers and a young mouse can get in through any hole with a diameter greater than 6mm. As many of the potential entry routes as possible should be blocked using rodent-resistant filling materials and nylon bristlestrip.
Eliminating rodent harbourages will also help reduce populations. Rodents need somewhere to hide and breed and any such areas should be identified and eliminated or made inaccessible.
Good sanitation is essential both inside and outside buildings. All rubbish and food spillage should be removed immediately as should any old tins or tyres capable of collecting rainwater. Refuse bins and skips should be kept covered and water leaks repaired. Sanitation in terms of disinfection is also important, in order to protect human health by controlling rodent-borne diseases. Apply a specialist disinfectant with proven efficacy against rodent-borne diseases, such as Leptospriosis, Hantavirus, E. coli and Salmonella spp.
PHYSICAL ABILITIES AND SENSES OF RODENTS
A thorough understanding of the physical abilities of rodents is very useful when designing a control programme. For instance, rats are excellent swimmers. They can swim up to half a mile in open water, travel through sewer lines against substantial currents and tread water for up to three days. Climbing is also easy for them. Roof rats and house mice are excellent climbers. Norway rats, although somewhat less agile, can climb effectively. If they can't climb, they just jump. From a standing position rats can jump vertically up to three feet - and getting down is easy. If necessary, rodents can drop from heights of 50 feet without injury. If rodents can't get around an object, they go through it. Rodents are capable of gnawing through a variety of materials including lead sheathing, cinderblock, aluminium siding, glass and improperly cured concrete. Rodents can also squeeze through very small openings - 15mm for rats and 6mm for mice. All of these physical abilities have allowed rats and mice to survive hundreds of years in man's environment. The following are some of the other sensory abilities that make rodents so remarkably adaptable.
Rodents use hearing to locate objects to within a few inches. Rats and mice have a frequency range of 50 kilohertz or more, which is much higher than humans who have a range of about 20 kilohertz. Rodents make high frequency noises in various situations such as in mating but the function of these sounds is poorly understood.
Rats and mice have poor vision beyond three or four feet but they are very sensitive to motion up to 30-50 feet away. For the most part, rodents are colour blind but very light-coloured or reflective objects may stand out in their environment and cause initial avoidance among sensitive rodents
Rodents have a highly developed sense of taste, which allows them to detect some chemicals at parts-per-million concentrations. This taste sensitivity may lead to bait rejection if the baits are contaminated with insecticide odours or other chemicals. Use of fresh, food-quality grain ingredients is the best guarantee of good bait attractability and acceptance.
Odour is one of a rodent's most important senses. Rodents mark objects and pathways to and from food sources, members of the opposite sex, who are ready to mate differentiate between members of their own colonies and strangers and to tell if a stranger is a strong or weak individual.
Rodents have a highly developed sense of touch due to very sensitive body hairs and whiskers (vibrissae), which they use to explore their environment. Most of a rodent's movement in a familiar area relies heavily on the senses of touch and smell to direct it through time-tested movements learned by exploration and knowledge of its home range. Rodents prefer a stationary object on at least one side of them as they travel and thus commonly move along walls, a fact which is very useful when designing a control programme. In captivity, rodents will hide quite contentedly in a clear glass jar since it "feels" enclosed and secure to them.
