Rat Exterminator - Apex Pest Control

HISTORY

Originated from Asia and China. First recorded in Europe at the beginning of the 18th Century. They were referred to as Norway Rats because they were thought to have travelled from the East on Norwegian timber ships.

HABITS

R. norvegicus must drink water daily unless the food is extremely moist

  • Colour: This can vary but usually brown to grey-black with lighter underside.
  • Ears: Small
  • Eyes: Small
  • Tail: Slightly shorter than head and body. The tail is dark above and lighter below.
  • Weight (adult): 400-500g
  • Litters per year: 3-6
  • Litter Size: 7-9
  • Maturity: 2-3 months
  • Average life span: 12 months

They are considered omnivorous but if available, cereals seem preferred.

They eat on average 10% of their body weight each day.

R. norvegicus explores locations quite freely and are “creatures of habit” in that they prefer to feed at certain locations.

However, it does have a fear of new objects. This is known as neophobia and this should be taken into account when baits are checked after an initial treatment.

RAT CONTROL METHODS

Our rat control is always tailored to each individual site of situation, as no two jobs are the same.

DOMESTIC PROPERTIES

Prior to carrying out any rat control treatment, a survey of the premises should be carried out to gain as much information of areas where rats are seen or heard, possible access points. This may require gaining access to sub floor areas, roof space, under kitchen units, airing cupboards, garages and outside areas. The more areas investigated, a better picture of the rats activity can be gained. At the time of the survey at least a mental risk assessment or a tick box risk assessment should be carried out.

Armed with the correct information gathered from the survey and a knowledge of rat biology and behaviour some of the signs we are looking for are:

  • Holes
  • Droppings
  • Runs
  • Smear mark
  • Smell
  • Damage
  • Gnawing
  • Dead or alive rats
  • Tracks
  • Nests

DOMESTIC TREATMENTS

Our treatment will require our initial visit and follow up visits, which will be determined, by our survey. Baits will be placed down in all areas where rats are going to come in contact with the rodenticide, but is safe to humans or non-target species. We use a 2nd generation rodenticide in formulations suitable for each individual job. The first follow-up visit will be carried out between 5 – 7 days later to check our baits and remove any dead rodents found. The second visit will give us further information, such as possible numbers of rats being dealt with, most frequented area visited etc. If necessary, more appointments for follow-up visits will be made until we are sure all rats have been dealt with. From the time of our last visit we give a 30-day guarantee that any further sighting we will re-treat free of charge. After this time, we class any signs as a fresh infestation.

FARMS

Farms come in many different shapes and sizes; living accommodation will be an integral part of the site so that children and domestic animals must also be considered. Stored animal feed and crops, bedding, even animal waste will be present an ideal environment to support a rodent infestation. Rodents living and feeding outside will enter buildings with the onset of the winter months.

Rats living indoors should be treated using bait stations placed in safe locations if accessible, and if contamination from spillage is a risk, blocks within tamper-resistant bait stations should be used.

Rats need ready access to a water supply, as they must drink daily. Runs to the water source may be evident and give an indication of harbourages. These may be evident as holes and if holes can themselves be baited safely, this should be done. To reduce the risk to non-targets, cover the holes with materials found in the location; stones, wood etc. Covering holes will also have the advantage of keeping the baits dry, keeping them palatable for longer. Ideally, the bait points should be at least 60cm down the hole to prevent children reaching the bait. To protect farm buildings from current rat activity, external bait points may be established, subject to justification and an environmental risk assessment. Fixed tamper-resistant bait stations for these locations would give the highest level of protection.

FOOD PREMISES

Concern in these locations is the risk of spillage and the resultant risk of contamination from the spilled rodenticide. This risk will be overcome by the use of block formulations. In very sensitive areas indicator blocks non-toxic blocks) can be used contained within tamper-resistant bait stations (both for rats and mice).

Internal bait points should be kept to a minimum and reduced once an infestation has been cleared. Fixings to walls and floors is desirable and far safer in production areas. Away from production areas, boiler rooms, false roofs, etc., are high risk and should be baited. Perimeter baits, if appropriate for the location, should be established, subject to justification and an environmental risk assessment. These should be of a fixed tamper-resistant type to give the highest level of protection to the bait. Internal locations of bait points in restaurants, kitchens etc., should be as for domestic premises.

In many premises, baiting of production areas is not permitted.

FOLLOW-UP VISITS

The usual follow-up time after the initial baiting programme has been established is seven days, although some situations may require daily visits. The commencement and frequency of follow-up visits to bait laid outdoors will be determined by factors such as size and extent of the infestation, risk to non-target species through exposure to bait or secondary poisoning and label requirements of the chosen rodenticide.

If bait stations are to be left in position outdoors as part of a pest control contract, they must be emptied of all bait at the end of a treatment.

Some locations will merit a more detailed reporting system to include bait plans, COSHH assessments, monitoring reports, and hygiene, housekeeping and proofing recommendations.
