How to control cockroaches

Determine which cockroach species you have

Cockroaches are difficult to control, mainly due to their habit of laying egg pouches,containing numerous eggs, in inaccessible areas.

There are two main species, Oriental (blatta orientalis) and German (Blattella germanica). Both these types of roaches have different habitats and habits and also look rather different from each other, so it should be fairly easy to identify which species of cockroach you are dealing with.

Oriental Cockroachs are generally found at floor level, are large (20-24mm), broad and reddish brown in colour. Reasonable climbers so check higher levels for activity too..

German Cockroaches are more often found off floor level and these are small (10-15mm) slim sandy coloured insects with clearly visible wing structures which are not developed sufficiently for them to fly. Excellent climbers, hence the higher levels at which you will find these cockroaches, they can even walk on ceilings and undersides of cupboards!Shop for Professional Insecticides-Rodenticides Products

German Cockroach Control Treatment

This sand coloured roach will generally be found at higher levels and, as with other cockroaches, is generally nocturnal in habit.

1. You will require to be rather investigative to find the hiding places of the German Cockroach. This species tends to live at higher levels than the Oriental Cockroach and treatment can be more difficult.

Essentially you need to carry out the same treatment as is outlined above but with more concentration on the higher levels.

2. You will need to apply insecticide to the backs of work surfaces, taking care to wipe off the front parts of treated work surfaces with damp paper kitchen towel, which can then be disposed in your rubbish bin.

Cockroach killer powder (Rentokil Ant & Crawling Insect Killer) may need to be applied inside electrical equipment such as coffee maker because the German Cockroaches like to live inside equipment, which does tend to make treatment much more difficult.

Lo-Line Cockroach Traps or Crawling Insect Monitors should be placed on work surfaces, in cupboards, on top of cupboards and a few at floor level in order to trap the German Cockroach.

Latest trends in cockroach control involve the use of food baits to poison cockroaches from within. Sadly, these baits are not available for non-professional use however, you can view these products on our Professional Insecticides page.

Oriental Cockroach Control Treatment

This reddish brown roach generally will be found at lower levels but can climb fairly well so will also turn up at elevated levels, and, as with other cockroaches, is generally nocturnal in habit.

1. Spray apply an insecticidal liquid around the total perimeter wall floor junctions of each affected room. Where roaches have been found at higher levels, then carefully apply product to those areas too. Products that are suitable for this purpose are, Pro-Active C water based low odour insecticide and Rentokil Insectrol Aerosol. The latter will not give such long term protection from cockroaches but may penetrate better under skirtings and into small voids.

Spray applied insecticides will require re-application after 15 days, then every 30 days after that until the infestation is clear.

2. Once the surfaces are dry you can apply an insecticidal dust such as Rentokil Insectrol Dust 150g to places where spraying can be difficult. Particular attention should be given to applying insecticidal powder into voids, under appliances ie: ovens, into pipe ducting, under raised base cupboards and behind fixed units. Cockroaches like all these areas.

3. Set up some cockroach traps. These come in two sizes, Crawling Insect Monitor is a small sticky trap that could catch maybe half a dozen cockroaches, it is, as the name indicates, a tool for monitoring cockroach activity and if you have a significant problem, then the Lo-Line Cockroach Trap would be a better investment. The majority of Traps should be placed at floor level with just a couple at higher levels, let’s say on kitchen work surfaces, where cockroaches like to forage for food.

How to control Carpet Moths

What do the Case Making Carpet Moth look like ?

Case Making Carpet Moth (Tinea pellionella)

The adult case-making carpet moth has a wing span of 15 – 17 mm.The head is covered in spiky scales. The forewings are pale brownish-grey with vague dark spots. The forewing may have 3 or more dark spots. The hind wings are pale fringed with long hairs. Both wings are narrow. The adult does not feed on the carpet. The adult can fly. They are short-lived.

Treatment Method for Case Making Carpet Moth

This moth is highly destructive and often astounds the homeowner with the extent of damage caused.

The Case Bearing Carpet Moth will normally attack high wool content carpets although will not restrict itself to this food source, it can also feed on clothing and cereal products.

Generally, this moth can be found around the edges of the carpet and more particularly under furniture, even furniture that is directly onto the floor ie: with no legs

February 2018 : We are now pleased to offer the new Acana Carpet Moth Trap and Refills

The most effective method of treatment is to spray the affected carpeting with a water based insecticide such as Pro- Active C comes in a 1 litre ready to use trigger spray to kill moths or a Pro-Active C 5 litre container of moth killer. For a belt and braces job, you may widh to also lift the edges of affected carpet and spray the back of the carpet, as the casemaking clothes moth may chew the knots holding the pile onto the backing material or even feed on the backing material if it comprises of a natural fibre. You can also use a moth killer dust under the carpet and furniture such as, Pro-Active Dust (diatomaceaous earth). Pro-Active Dust is very long lasting if kept dry, up to ten years moth killing ability can be expected This dust is a natural product and therefore is very safe, although we suggest a mask when using, as it will dry the nasal passages rapidly if inhaled.

There are differing views as to what area you need to apply insecticide when dealing with Case Making Carpet Moth, generally, treatment around the edges of a room and under any furniture will suffice. By “edges of the room” we mean to treat a band approximately 500mm wide out from the skirtings. This treatment will last around 3 months, re-apply if necessary.

External walls are the most high risk area as the carpet abutting external walls is generally of a higher moisture content, which the moth prefer over a totally dry carpet!

Ant Control (indoor and garden)

Shop for Ant Killer Products

For much of the year, Ants can be a serious problem, although they are considerably less active in the winter months.

You can choose which products suits your particular problem or call us for advice.

Here is some information and advice about dealing with an ant infestation.

In this article

Ant Basics – About Ants

There is one main Ant species that causes the most infestation issues in the UK, the Black Garden Ant (Lasius niger).

The Red Ant (Myrmica rubra) a problematic Ant that has the ability to sting humans and therefore cause irritation. Watch out for a new product coming to combat these in late March 2020.

There are many other types of ants and it is fairly important to identify the type of ant you are dealing with in order to be able to resolve the problem.

Most people recognise the Common Black Garden Ant, but ants such as the Pharoah’s Ant will be much harder to identify and you may need to seek our help for anything other than the Black Garden Ant.

Incidentally, this ant does not restrict itself to the garden and is a major indoor pest, seeking food from your home, often, high sugar or protein content foods but any human food may attract an army of these little pests. It is very rare for this ant to nest indoors!

Most ant colonies have a queen, the queen stays in the nest, which in the case of the Black Garden Ant is generally located underground. You need to kill the queen in order to achieve total eradication of an ant problem and please consider that there could be more than one nest!

The queen ant lays many thousands of eggs during her extensive lifetime (up to 30years!)

Flying ants are mainly fertile female ants, bred in the nest in early spring, that leave the nests in May or June and fly high and spread to form new nests. Further information in the next section below.Shop for Ant Killer Products

Evaluation and preparation for treatment

Before commencing the treatment is is important to find where the Ant nest is located, if that is possible, as the closer to an ants nest the treatment is targeted the more successful it will be.

If the ants are inside the house and they are the black ant, follow their route source until it enters the structure of the building, ie: under the kitchen sink, then look outside the house in that immediate area to check if they are visibly evident outside, if so, keep following the route until it enters the ground. The nest should be near this point.

If there is no evidence of an ant run outdoors then your ant control treatment will need to be carried out mainly indoors.

If your treatment is going to be an indoor one using an ant killer spray, Pro-Active C for Ants remove any uncovered foods and unprotected eating/cooking utensils from the treatment area.

If your treatment involves outdoor spraying, then move any pots or loose garden ornaments to 2 metres away from your treatment area to enable complete ant killer insecticide application.

Most ants nest outdoors. To keep them from migrating indoors, a little preventative maintenance is necessary. If your home is prone to ant infestation, spray an insecticide formulated specifically for outdoor ant removal around the outside perimeter of your house and include to spray any wall air vents and around window and door frames.


Flying ants are usually a problem on hot days in May or June. Outdoors they are not something you can treat but indoors you may want to use a normal fly killer aerosol spray or insecticidal smoke generator.

Opening windows can resolve the problem as the flying ants actually desire to get into the air at high levels, so if they accidentally get into your home, releasing them is the easiest and greenest solution.

Try to find the access point and seal.

Effecting the Ant Control treatment

Having searched carefully you are now ready to tackle the ant problem. We strongly recommend the use of Maxforce Ant Bait Stations, which are small plastic receptacles containing a gel which will be eaten by some ants and carried to feed the larvae and queen by other ants.

This bait can take one or two days to work as it is purposefully slow acting to allow the ants to carry it back to the nest and feed the ant larvae and hopefully the queen too. These can be used indoors and outdoors and we suggest two bait stations per nest of ants.

If you prefer a more rapid result, then we suggest our Pro-Active C Ant Killer spray, which is applied to all the areas where the ants are know to be moving.

This product, once applied and dry, will kill within hours of contact with the ants. It can be used inside the house and is safe to children and animals once dry.

When treating near or alont the back of kitchen worktops, wipe down food prep areas with a damp disposable cloth/paper towel after the treatment and perhaps leave a small band of insecticide along the back of the work top.

Remove any live fish, or animals from the room being treated and return them after 4 hours.

We also suggest keeping children out of the treatment area for the same period of time.
