spiders control in and around the home

Though some spiders are known as being quite fatal, they too have some benefits. For example, spiders help in the control of insects in our homes by feeding on them. This does not mean spiders should be wholly tolerated. Many people tend to mistake spiders with insects, which is not correct, several things distinguishes them.First,spiders have eight legs whereas insects have six,spiders also are segmented into two body parts whereas insects are segmented into three among other slight differences.

Several methods can be undertaken for control of spiders.                

                     I  through barring entry of spiders

It’s always said prevention is better than cure. Therefore prevention of spiders from getting into your home is key in control of  spiders.This can be achieved through sealing all the cracks and crevices through which the spiders can enter your house. Doors and windows should be regularly inspected so as to ensure there are no holes or openings for entry of spiders. Gaps below the doors and windows should also be checked and sealed

                    II.            Through observing sanitation

Spiders are prone of taking shelter in stuff that are rarely moved in homes. So as to get away with such haborages, one should remove any trash, unused cottons and all other unused items.Regular sweeping and dusting should also be frequently done, not forgetting removal of cob webs.                             

               III.       the use of non-chemical method

This can be done through the manual removal of spider eggs. To achieve this one should use either gloves or a piece of cloth then pick the spider web and its eggs and discard it. A vacuum cleaner can also be used to destroy the web and egg. Use of sticky insect traps  also is employed where they should be placed in corners and along baseboards so as to get hold of moving spiders                        

                 iv.            Use of chemical control

Chemical spider control can be achieved through the use of residual insecticides. The insecticides should be sprayed on corners and in places where the spiders spin their webs and lay eggs.          

              V.            Control of spiders outdoors

This is done through the removal of spiders that have their harborage on buildings by use of water under very high pressure.

Besides that, there are other general preventive techniques that can be employed:

  • Tree branches that lead into and touch your home should be trimmed. This will help in the elimination of the pathway of pests like spiders’ into your home
  • Regular inspection should be carried out on your doors and windows to check whether there is the existence of cracks or holes. If they are there they should be repaired.
  • Also, its important to keep your compound free of litter, standing water or weeds that may form harborage for pests. People should also ensure that litter bins have tight fitting lids. Regular sweeping should also be done around the dust bins and all the spills and debris removed. This will deny the spiders a source of food.
  • Fourth all the cracks and gaps inside your house should be sealed as they can form a pathway for spiders.
  • Lastly people should always keep their homestead clean, since the cleaner the home is, the lesser will the pests be attracted.

Control of bees

Classification of honey bee














Apis Mellifera

Bees are closely relatives to ants and wasp. They play a very important role in the sustenance of life on earth. However, they can also be pests.

Importance of bees

·         The most notable contribution of bees is pollination. Without bees, life would not exist as it is today. Pollination leads to seed production

  • ·         Increasing bio-diversity because of cross pollination
  • ·         As producers of honey
  • ·         As cultural, mythical examples of hard work, diligence and organization  

Bees as pests

Bees can only be considered pests when they endanger the lives of humans, livestock and wildlife. This is only relevant to stinging bees and when they swarm around humans. In general, bees will not sting until disturbed

Life threatening allergies (anaphylaxis)

To some people, bee stings can cause life threatening allergies known as anaphylaxis. This occurs in some people in a population. Again, the reaction could differ depending on the bee species. It is therefore extremely important to eliminate bees from human residences especially if there are young children. This is because the reactions to bee stings may not be known.

Treatment of bee stings

  • Remove the stinger as soon as possible
  • Apply a weak base/alkali such as tooth paste or soap. Bee sting is highly acidic containing melittin
  •   A tetanus injection may be required
  •   For serious reaction, get to a health facility as soon as possible where the doctor may prescribe epinephrine injection

Control of bees

  • Fumigation or spraying with an appropriate insecticide will often control bees. Pest control professionals will prescribe control and preventive measures to discourage re-colonization.
  •   Prevent entry and colonization by entry proofing. Bees will mostly be found in ceilings, chimneys and between panels in a building
  •   Where, pesticides are used, all the honey and honey combs must be disposed of well by the pest control professionals. No trace should be left at the sit
  • Usually, the control of bees is done in the evening and uses smokers. Appropriate PPE must be worn during the activity.


Cockroach control

Controlling cockroaches in kitchens, homes, restaurants, hotels, offices and other business premises

Cockroaches inhabit the human habitat for survival and nourishment. The most common cockroaches are the German cockroach, the American cockroach, the oriental cockroach and the Australian cockroach. In general, the approaches for control are similar for all the species


Where cockroaches hide

  • Under the refrigerator
  • Under the microwave
  • Under the TV and the entertainment system
  • Under mattresses and
  • Under seat cushions

These are also the preferred egg laying areas. Other areas where you are likely to find cockroach eggs are

  • At the rubber around the refrigerator doors (i.e door gasket) and
  • On shelves that are difficult to reach (usually the high ones).


Check all the areas above and pay special emphasis to the refrigerator rubber and the higher shelves and surfaces


Cockroach Pest species

There are many species of cockroaches. The common species that are pests include

·         American cockroach (Periplaneta Americana)

·         German cockroach (Blattella germanica)

·         Asian cockroach (Blattella asahinai)

·         Oriental cockroach (Blatta orientalis)

In Kenya, the common ones are the American Cockroach and the German cockroach with the American cockroach being the larger one (about 30mm long) and the German cockroach being the commonly seen small ones (about 15mm long) as adults.

Control of cockroaches


Hygiene is the best method. However, this is the most difficult to achieve as a result of the influence of the external environment. Whilst your place could be clean, your surroundings and neighbors may not be as clean as you are. Again, sewerage lines and plumbing lines are usually interconnected. This provides a route though which the cockroaches move from one place to the other, regardless of the hygiene standards of the place in question. Hygiene is still very important in discouraging the cockroaches from foraging in your kitchen, house, restaurant, office or business premises

Other methods of control include

Where infestation is heavy other control methods must be considered, these usually involve the application of insecticides in form of

·         Spraying or fumigation

  • Contact spraying
  • Indoor Residual spraying

·         Application of baits in form of gels, powders, or pastes

·         Use of insecticidal chalks

Do it yourself (DIY) techniques

One can purchase a suitable insecticide and apply using any of the above methods. However, the impact may be unsatisfactory because of the following.

·         Choice of the product to use. Cockroaches have become resistant to the most commonly used pesticides. As such, the “do it yourself” approach can in some instances lead to unsatisfactory results

·         Targeting the pests effectively. Effective targeting of the pests means targeting them where they are, when they are most vulnerable and targeting the right stage in the life cycle

·         Equipment: The application equipment should be able to provide sufficient coverage for the intended purpose. In general, small hand pumps are not suitable for heavy infestation

·         The need to guarantee health, safety and environmental concerns.  When fumigating or carrying out pest control at home, ensure that the safety of people, pets and the environment is not compromised.

·         Lack of time. For busy persons, own pest control can be difficult.

Should you decide to do it yourself

·         Keep pesticide containers and pesticides away from people especially children
·         Keep pesticide and pesticide containers away from food and water
·         Triple rinse all empty pesticide containers and dispose of in a licensed facility
·         Follow the label instructions

Is Pest Control the same as Fumigation

Pest control and fumigation in Kenya

In Kenya, pest control and fumigation as terms are used interchangeably. Pest control is a general term which involves many techniques that are used to control pests. This include fumigation, spraying, drenching, entry proofing, trapping and many other pest control methods.

Fumigation is therefore a subset of pest control. Fumigation is the use of fumes often for pest control purposes. For fumigation to be effective, the chemical or pesticide fumes are enclosed for a certain duration of time. This is to give the pesticide and the target pest(s) enough exposure time.

Common fumigants include insecticides and nematicides (with nematicides being products that kill nematodes). Nematicides in general kill nematodes, insects, weeds and many other life forms in soil and in growing media.

Strictly speaking, fumigation is rarely done in homes because for home services, safety is important and the re-entry time is much shorter.Therefore, a professional pest control technician should spray a house, office or work place while the windows are open. The doors can be closed to restrict entry by other people not involved in pest control.


Fumigation is usually done to control insects on grains, timber/wood and other stored materials. This is to protect them against insects like weevils, beetles and termites. The process involves covering the materials to be fumigated using airtight plastic or tarpaulin sheets. Fumigants are then injected or placed in the enclosure in such a way that no fumes or gas escapes. After several hours or days, the covering sheet is opened to release gases while ensuring that people, livestock or pets are not exposed to any harm.

Examples of fumigants include methyl bromide (which is banned in many countries for its adverse effects on the ozone layer), metham sodium (or metam sodium) and basamid (dazomet). These are mainly used in soil and growing media fumigation. For grains, celphos (phosphine) and Actellic (Pirimiphos Methyl)are commonly used in Kenya. There is a form of actellic that is also used for public health and can be used in homes and offices. Actellic is very effective agains moths, weevils and other flying insects and kills on contact.

For more information on these, one can get in touch with pest control and fumigation companies in your area whether in Kenya, Nairobi or elsewhere.


How to control bedbugs infestation

How to control bedbugs


To avoid infestation

New infestation frequently comes from interacting with the infestation. These can be

·         By sleeping elsewhere apart from home

Use of public transport like taxis and buses

After a road trip by, say to Kampala or Kigali or even with the country by bus or taxi , the following actions will keep you safe from bedbugs

·         Unpack in the open or in the laundry room and not in the bedroom, sitting room and any other rooms

·         Change clothes and take them to the laundry room as soon as possible. If this is not practical for you, change clothes, bag them in a polythene bag and keep them away from other clothes

·         Wash them as soon as possible and dry them in the sun

To treat infestation

Call pest control professionals so that the safety of children and other occupants of the home or facility is assured. The pest control professionals understand bedbug behavior and life cycle and will give you appropriate advice

In general, one treatment is unlikely to eliminate an infestation and follow up treatment is required

To reduce bedbug populations

·         Keep the houses and rooms well lit

·         Air the bedding, seat covers, cushions and other laundry in the sun

·         Keep items like beds, sideboards, bookshelves and clothes away from walls and off the ground

·         Regularly clean the surfaces and laundry
