You want to keep pests out of your home. You know you should spray regularly. But where do you start? What products do you buy? How do you apply them safely? How often should you do it?
This quick start guide answers all those questions. It is designed for busy homeowners who want a simple, effective system without the confusion. No jargon. No fluff. Just clear, actionable steps to get you started today.
Whether you live in Lagos, Abuja, Port Harcourt, or anywhere else in the world, this guide gives you a framework that works. Let us get started.
What You Will Need
Before you begin, gather these items. Most are available at your local hardware store or supermarket.
Essential Equipment
| Item | Purpose |
|---|---|
| Insecticide spray (ready-to-use or concentrate) | Kills and repels pests |
| Spray bottle or pressure sprayer | Applies the insecticide |
| Nitrile or rubber gloves | Protects your hands |
| Safety goggles | Protects your eyes |
| Face mask | Prevents inhalation of fumes |
| Long-sleeved shirt and trousers | Covers your skin |
| Old newspapers or drop cloths | Protects furniture and floors |
| Measuring cup (for concentrates) | Ensures correct dilution |
| Notebook or phone | Records spray dates |
Optional but Helpful
- Extension wand for hard-to-reach areas
- Door sweep or caulk for sealing entry points
- Yellow sticky traps for monitoring
Your 10-Step Quick Start Plan
Follow these steps in order. The entire process should take about 1–2 hours for a typical home.
Step 1: Set Your Spray Day
Choose one day each month and stick to it. The first Saturday of every month works well for most people.
- Mark it on your calendar.
- Set a phone reminder one day before.
- Treat it like any other important home maintenance task.
For Lagos and other tropical areas: During the rainy season (March to October), consider spraying every three weeks instead of monthly.
Step 2: Choose Your Product
Walk into any store, and you will see dozens of pest control products. Here is how to choose the right one:
For indoor use:
- Look for "indoor use" on the label.
- Choose low-odour, low-toxicity products.
- For kitchens, select products safe for food-contact surfaces.
For outdoor use:
- Look for weather-resistant products.
- Choose products with "residual effect" (lasts for weeks).
Ready-to-use vs. Concentrate:
- Ready-to-use: Already mixed. Just spray and go. More expensive but convenient.
- Concentrate: You mix with water. Cheaper but requires measuring.
For beginners, start with ready-to-use. Once you are comfortable, switch to concentrate to save money.
Popular brands available in Nigeria include Sniper, Kilit, and Raid. Always read the label to confirm effectiveness against your specific pests.
Step 3: Read the Label
This is the most important step. The label contains:
- Active ingredients
- Dilution ratio (if concentrate)
- Application instructions
- Safety warnings
- First aid information
Read it completely before you open the product. Keep it nearby during spraying.
Step 4: Prepare the Area (Spray Day)
Before you spray, prepare your home:
1. Evacuate children, pets, and other family members to a safe area outside or in an untreated room.
2. Remove or cover all food, dishes, cups, and utensils. This is especially important in the kitchen.
3. Cover furniture with old newspapers or drop cloths. Focus on sofas, beds, and tables.
4. Turn off air conditioners, fans, and other devices that circulate air.
5. Open windows to ensure proper ventilation.
Step 5: Put On Your PPE
Never spray without proper protection.
Put on your gear in this order:
1. Long-sleeved shirt and full-length trousers
2. Safety goggles
3. Face mask
4. Gloves (pull them over your shirt cuffs)
Check that no skin is exposed. It may feel uncomfortable, especially in Lagos's warm climate, but safety comes first.
Step 6: Prepare the Spray
If using ready-to-use spray:
- Shake the bottle well.
- Test the spray on a small area to check the pattern.
- You are ready to go.
If using concentrate:
- Read the label for the correct dilution ratio.
- Fill the sprayer halfway with water.
- Add the recommended amount of concentrate.
- Secure the lid and shake well.
- Add the remaining water and shake again.
Important: Never guess the dilution. Too much concentrate is dangerous. Too little is ineffective.
Step 7: Spray Indoors (From the Inside Out)
Start in the furthest room from the exit and work your way toward the door. This prevents you from walking through freshly sprayed areas.
Spraying technique:
- Hold the nozzle about 30 centimetres from the surface.
- Use a sweeping motion for even coverage.
- The surface should be damp—not dripping.
Priority indoor areas:
| Area | What to Spray |
|---|---|
| Kitchen | Under the sink, cupboard cracks, around the bin, behind the refrigerator |
| Bathroom | Around pipes, corners, behind the toilet |
| Bedrooms | Baseboards, window sills, door frames |
| Living Room | Behind furniture, near curtains, entry points |
| Storage areas | Corners, shelf gaps, around boxes |
Do not spray:
- Food preparation areas
- Dish storage
- Children's toys
- Pet bowls
Step 8: Spray Outdoors (From the Outside In)
After completing indoor spraying, move outside. Start from the outer perimeter and work toward the house.
Choose the right weather:
- Spray on a day with little or no wind.
- Avoid spraying if rain is expected within 24 hours.
- Early morning or late evening is best—avoid midday heat.
Priority outdoor areas:
| Area | What to Spray |
|---|---|
| House perimeter | A 30–60 centimetre band along the foundation |
| Doors and windows | Frames, sills, and surrounding cracks |
| Garden areas | Stagnant water, around vegetation, near trash storage |
| Boundary walls | Base of walls, gate posts, entry points |
Step 9: Wait and Ventilate
After indoor spraying:
1. Leave the treated area immediately.
2. Close the doors and windows (if the product label requires it).
3. Wait for the time recommended on the label.
4. Return and open all windows and doors for thorough ventilation.
5. Wait until all surfaces are completely dry before allowing children and pets to re-enter.
After outdoor spraying:
- Allow the product to dry for at least 1–2 hours.
- Keep children and pets away from treated areas during this time.
Step 10: Clean Up and Record
Remove PPE:
1. Remove gloves first (peel them off carefully).
2. Remove the rest of your gear.
3. Place used gloves and masks in a sealed bag for disposal.
Clean up:
- Wash your hands and any exposed skin with soap and water.
- Change clothes immediately and wash them separately.
- Clean spray equipment (if using reusable devices).
Record:
- Write down the date of the spray.
- Note the product used.
- Record any observations (e.g., "saw fewer mosquitoes this week").
This record helps you track progress and plan future sprays.

- Frequently Asked Questions
Q1: How long does a monthly spray routine take?
For a typical home, the entire process takes about 1–2 hours, depending on the size of your home and the number of rooms.
Q2: How soon can I see results?
You will see immediate knockdown of visible pests within minutes. For full control, allow 2–3 monthly cycles for complete population reduction.
Q3: What if it rains after I spray outdoors?
Rain can wash away outdoor sprays. If it rains within 24 hours of spraying, reapply the outdoor perimeter spray.
Q4: Can I spray if I am pregnant?
Consult your doctor before handling any pesticides. Consider hiring a professional or using non-chemical methods during pregnancy.
Q5: What if I have pets?
Remove pets from the area before spraying. Keep them away until surfaces are completely dry. Store all products in a locked cabinet.
Q6: How do I know if I am using too much product?
If surfaces are dripping wet, you are using too much. The surface should be damp, not saturated. Always follow label instructions.
Q7: Can I spray in the same room where I sleep?
Yes, but take extra precautions. Remove bedding and pillows, cover the mattress, and wait until surfaces are dry and well-ventilated before sleeping in the room.
Q8: What is the cost of a monthly spray routine?
In Nigeria, a monthly routine can cost between ₦5,000–₦15,000, depending on the products used and the size of your home. Concentrates are more economical long-term.
Q9: Should I spray if I don't see any pests?
Yes. Preventive spraying is more effective than reactive spraying. It stops pests before they establish populations.
Q10: Can I use the same product indoors and outdoors?
Check the label. Some products are for indoor use only, others for outdoor use only. Using an outdoor product indoors can expose you to toxic fumes.
