Protect your family and home from flies, spiders and other crawling and flying pests.
Did you know that you can treat the surface of an area, like walls and ceilings, and it can provide months of protection from insects like spiders, flies and cockroaches? Surprised? You’re not alone, products like these are called residual surface insecticides and they’re an easy DIY pest control solution that surprisingly few people are aware of. And it’s a great tool to have in your toolkit not only for preventative purposes, but also if you’re dealing with an infestation.
Early spring is the best time to carry out fly and spider preventative treatments around your home. Products like NO Bugs Super, NO Bugs Indoor, Ripcord Plus and NO Spider Total Protection are surface insecticides that provide long lasting protection. They should be applied on exterior and interior surfaces where insects crawl or land. should applied on exterior and interior surfaces where pests crawl or land. Places like eaves, downpipes, sunny walls, around doors and windows, the base of walls and around vents should be treated. This will get rid of unsightly cobwebs and act as a barrier to insects and other pests that might try and get into your house.
Spring treatment will greatly reduce the number of pests that would annoy you though the warmer months. Although, a second, top-up treatment, may be necessary later in summer
Residual insecticides are insecticides that remain active and lethal to insects for up to 6 months. Pyrethrum is a natural product extracted from the flowers of chrysanthemums. Synthetic versions of pyrethrum are made more stable and long lasting and are known as pyrethroids.
Surface sprays only affect insects when the insect makes contact with the treated surfaces or if the insect is sprayed directly. This is great for controlling crawling insects both adult and larval. Flies and other flying insects are also controlled because they will land on the treated surfaces. The long lasting effect of residual insecticides means that a treatment can be carried out once and may not need repeated for a whole season. Because the insecticide is limited to the treated surfaces there is no insecticide in the air for people, pets or others to inhale.
How to Use Residual Surface Insecticides
- Think about the pest/s you want to control. Where do they live and what surfaces do they contact?
- If the surfaces to be treated are dirty or greasy clean them with mild detergent and leave to dry thoroughly.
- If you are using your own sprayer make sure it is thoroughly cleaned and rinsed with clean water before use.
- When using a concentrate, measure the correct amount of product carefully, and mix with clean water to the correct dilution.
- Clear away all foods, food utensils, and cover any surfaces that food may contact.
- Remove all people and pets from the area. Remove or cover fish tanks and ponds. Remove or cover toys and bedding or any other items that are regularly contacted.
- For exterior spraying choose a still dry day when rain is not imminent.
- Exterior spraying can be useful barrier to the entry of insect pests such as ants, cockroaches, slaters, flies and spiders.
- Wear overalls, particle mask, gloves, cap and eye protection when spraying.
- For crawling insects, pull furniture away from walls so that you have access to skirting and the base of walls.
- Using a fine spray and a steady motion spray the surfaces to give an even coverage. Do not over spray; the spray should not run.
- Porous surfaces are likely to need a second coat.
- If the spray beads on the surface let it dry and then give a second spray. Two light sprays is better than one heavy spray.
- When spraying around windows avoid over spraying on the glass. It is easier to clean spray off windows before it is dried. A sponge can be a useful way to applying spray solution to window frames and sills without getting product on the glass.
- Leave the area to ventilate and let the spray dry thoroughly.
- Wipe down any food preparation surfaces that might have had spray contact it.
- Synthetic pyrethroid insecticides take minutes to hours to kill insects so don't expect insects to drop dead immediately they contact the treated surfaces.
- You should now have good long term control of many insect pests. The length of time the spray will remain active is governed by the exposure to UV light, rain, grease and dirt accumulating on the surfaces and how often the surfaces are cleaned down.
